Description

[0001] APPARATUS AND METHOD FOR CALCULATING DESIGN LOAD [0002]

The present invention relates to a design load calculation apparatus and method.

It is necessary to design the structures to bear these loads by calculating the various loads applied to the structures during the construction of the structures. The load that is reflected in the design in anticipation of acting on the structure is called the design load. The design loads are classified into fixed, load, wind, seismic load, impact load, etc. depending on the cause.

Wind loads are caused by wind, and various parameters such as ground surface roughness, wind speed altitude distribution coefficient, and topographic coefficient are required to calculate wind load in order to calculate the wind load. In addition, under snow load, snow load is applied to the structure, and various parameters such as basic ground snow load are also used in the calculation of the load. Seismic load is a load acting on a structure due to an earthquake, and it is a parameter used in calculation of seismic load.

In general, various methods used to calculate the design load and to calculate the load are defined in the Building Structure Standard (KBC). However, the building structure standard (KBC) does not specify the parameters used for the design load, but presents only the ambiguous application criteria or estimates the parameters at individual points where the structure is manufactured through measurement.

In the case of the ground types used for earthquake load calculation, the KBC can be used to measure the ground shear wave velocity at the point where the building is constructed or to calculate the N value through the standard penetration test, To be determined. However, there is a problem in that, when the measurement or the test for determining the type of the ground is performed for each individual construction site, the increase in the production cost and the delay in the construction period are inevitable.

FIGS. 2 and 3 are exemplary diagrams for explaining a process of obtaining a parameter or an attribute value of a target point X based on sample points P1 to P12 according to an embodiment of the present invention.

In order to calculate the design load on the structure, the information collecting unit 111 may collect position information and parameter or attribute values of a plurality of sample points. According to the embodiment of the present invention, the sample point is a point at which a parameter or an attribute value used for calculating the design load for the structure is predetermined.

Here, the parameter is a numerical value or a grade used to calculate the design load. For example, in the case of wind load calculation, numerical parameters such as wind speed altitude distribution coefficient, terrain coefficient, basic wind speed are used and grade parameters such as surface roughness are used, In the case of tilting calculation, the same level parameter as the basic terrestrial snow load is used. In the case of seismic load calculation, the same grade parameter as the ground type can be used, but the type of parameter is not limited thereto.

According to an embodiment of the present invention, the target area may be a region including a location where the structure is located, and having a predetermined shape and size.

For example, as shown in FIG. 2, the object area 20 may be a circular area having a predetermined radius around a point S at which the structure is located, but the shape and size of the object area may be But is not limited thereto.

As shown in FIG. 2, one or more sample points P1 to P12 to which a parameter or an attribute value is assigned may be located around a point S at which the structure to calculate the design load is located.

According to one embodiment of the present invention, the information collecting unit 111 collects position information and parameter or attribute values of a plurality of sample points P1 to P12 located around a point S at which the structure is located And a parameter to be used for calculating the design load of the structure can be calculated based on the calculated load.

According to one embodiment, the information collecting unit 111 acquires a predetermined number of points from sample points to which the parameter or attribute value is allocated, in the order close to the point S at which the structure is located, as sample points You can choose.

For example, a plurality of points to which the parameter or the attribute value is allocated are located around a point S at which the structure is located. However, the information collecting unit 111 may calculate the point S), it is possible to collect the position information and the parameter or attribute value by selecting 12 points as the sample points P1 to P12.

According to another embodiment, the information collecting unit 111 can select, as sample points, points located in an object area having a predetermined shape and size from among the points at which the parameter or attribute value is determined.

For example, as shown in FIG. 2, the information collecting unit 111 sets a circular area 20 having a predetermined radius around a point S at which the structure is located as a target area, It is possible to collect the positional information and the parameter or attribute value by selecting the points P1 to P12 where the parameter or the attribute value is previously determined as the sample points, which are located in the object area 20.

The position information and parameters or attribute values of the sample points P1 to P12 may be stored in the storage unit 12 included in the design load calculation apparatus 100, The position information and parameter or attribute values of the sample points P1 to P12 can be retrieved from the storage unit 12. [

The design load calculation apparatus 100 may include a communication unit 10 capable of transmitting and receiving data through a network and the information collection unit 111 may receive the sample The server 200 may be provided with the location information and the parameter or attribute value by accessing the server 200 providing the location information and the parameter or attribute value of the points P1 to P12.

The design load calculation apparatus 100 may include an input unit 13 for receiving data from a user and the information collection unit 111 may receive the data from the user through the input unit 13, Positional information of the sample points P1 to P12 and parameters or attribute values may be input.

Then, the target information obtaining unit 112 may obtain parameters or attribute values of a plurality of target points using the positional information of the sample points P1 to P12 and the parameter or attribute value.

According to the embodiment of the present invention, the target information obtaining unit 112 obtains a parameter or attribute value of a plurality of target points using an interpolation method based on positional information of the sample points P1 to P12 and parameters or attribute values Can be obtained.

For example, the target information obtaining unit 112 sets the position information of the sample points P1 to P12 in the three-dimensional coordinate space as the x-axis coordinate and the y-axis coordinate, and sets the parameter or attribute value (X, y, z) of the sample points (P1 to P12) in the three-dimensional coordinate space by setting the coordinates of the sample points (P1 to P12) to the z-axis coordinate.

Then, the target information obtaining unit 112 obtains the z-axis coordinate of the target point by inputting the x-axis coordinate and the y-axis coordinate corresponding to the position of the target point to this function, Value can be calculated.

In this manner, the target information obtaining unit 112 can obtain the parameter or the attribute value of the target point where the parameter or the attribute value is not determined using the sample points P1 to P12.

Referring to FIG. 3, the plurality of target points X may be uniformly distributed around a point S at which the structure is located. According to this embodiment, the target information obtaining unit 112 uniformly distributes the target points S 1 to S 12 around the point S at which the structure is located using the sample points P 1 to P 12 that are unevenly distributed X). ≪ / RTI >

However, the plurality of target points X do not necessarily have to be uniformly distributed at regular intervals, and may be non-uniformly distributed around the point S where the structure is located according to the embodiment.

Then, the representative value calculation unit 113 statistically processes a parameter or an attribute value of a point in a target area including a point S at which the structure is located to calculate a representative parameter or a representative attribute value of the target area .

4 is an exemplary diagram for explaining a process of calculating a target area 30 and its representative parameter or representative attribute value according to an embodiment of the present invention.

According to an embodiment of the present invention, the target region 30 may include regions having the same shape and size as the parcel to which the structure belongs.

The point S at which the structure is located can be specified by a predetermined two-dimensional coordinate (x, y) on the map, but according to the embodiment, the point S at which the structure is located is determined by the address .

For example, the design load calculation device 100 may display a map of an area where the structure as shown in FIG. 4 is to be located through an output unit 14 such as a monitor. The user can designate or input the point S at which the structure is to be positioned through the input unit 13. [

According to the embodiment, the user may input the parcel address at which the structure is to be located via the input unit 13, instead of specifying the point S at which the structure is located directly on the map. In this case, the target area corresponds to a parcel to which the structure belongs. Referring to FIG. 4, the target area may be an area 30 having the same shape and size as the parcel to which the structure belongs. That is, the target area may be a region 30 having the same boundary as the parcel to which the structure belongs on a map of an area where the structure is to be located.

However, the target area need not necessarily be the same as the parcel to which the structure belongs, and may differ in shape and size from the parcel to which the structure belongs according to the embodiment.

5 is an exemplary diagram of a target region 30 'according to another embodiment of the present invention.

According to another embodiment of the present invention, the target area overlaps the parcel to which the structure belongs, and at least one of the shape and the size may be different from the parcel to which the structure belongs.

For example, as shown in FIG. 5, the target area may be formed by overlapping not only the area 30 having the same shape and size as the parcel to which the structure belongs but also the shape of the parcel 30 to which the structure belongs, Both the shape and the size may be a region 30 'that is different from the parcel 30.

For example, referring to FIG. 5, the target area 30 'may be an area partially overlapped with the parcel 30 and having the same area but a square shape. As another example, the target area 30 'partially overlaps with the parcel 30, but may differ in area and shape.

The target region 30 'may share a center with the parcel 30 when the target region 30' and the parcel 30 are overlapped. However, according to the embodiment, the target region 30 ' (S) at which the structure in the parcel 30 is located.

As described above, in the embodiment of the present invention, the target area used for calculating the design load for the structure is set to have the same boundary as the parcel to which the structure belongs, or may be set in a more simplified form to obtain the parameter or attribute value .

According to an embodiment of the present invention, the representative value calculation unit 113 statistically processes parameters or attribute values of a target point X located in the target area 30, 30 ' ') Or the representative attribute value of the representative attribute. In other words, the basic data of the statistical process used for calculating the representative parameter or the representative attribute value may be a parameter or an attribute value of the target point X located in the target area 30, 30 '.

According to another embodiment of the present invention, the representative value calculator 113 statistically processes parameter or attribute values of a sample point and a target point X located in the target area 30, 30 ' 30, 30 ') or the representative attribute value of the representative attribute. That is, this embodiment uses the parameter or attribute value of the sample point as well as the target point X located in the target area 30 or 30 'as the basis data and outputs the representative parameter or the representative property value Can be calculated.

6 is a graph in which parameters or attribute values of points in the target area 30, 30 'are arranged in the order of magnitude according to an embodiment of the present invention.

According to an embodiment of the present invention, the representative value calculation unit 113 may calculate a maximum value, a median value, an average value, or an optimal value of a parameter or an attribute value of the points in the target area 30, 30 ' 30) or a representative attribute value.

For example, referring to FIG. 6, the parameter or attribute value at the center of the points in the target area 30, 30 'is 7.5, the largest parameter or attribute value is 36, The attribute value is 15. The representative value calculation unit 113 statistically processes parameters or attribute values of the points located in the target area 30 and 30 'and calculates a mean value, a median value, a maximum value, and a median value from the parameters or attribute values of the points. And the calculated value may be determined as a representative parameter or a representative attribute value of the target area (30, 30 ').

7 is an example of a frequency distribution diagram showing a frequency distribution of parameters or attribute values of points in a target area 30, 30 'according to an embodiment of the present invention.

According to another embodiment of the present invention, the representative value calculation unit 113 calculates a frequency distribution of parameters or attribute values of points in the target area 30, 30 ' The class value of the class can be determined as the representative parameter or the representative attribute value of the target area 30, 30 '.

For example, as shown in FIG. 7, the representative value calculation unit 113 divides the parameter or attribute value of the points in the target area 30 or 30 'into a plurality of ranks, It is possible to calculate the frequency distribution of the sequence by calculating the frequency of the point.

The frequency distribution diagram shown in FIG. 7 divides the parameters or attribute values of the points in the target area 30, 30 'into four classes, but the number of classes is not limited thereto. The size of each class constituting the frequency distribution may be set in advance in the design load calculation device 100 or may be inputted from the user through the input unit 13. [

Then, the representative value calculation unit 113 can determine the rank value of the rank having the highest frequency in the frequency distribution as the representative parameter or the representative attribute value. For example, in the frequency distribution diagram shown in Fig. 7, the rank with the highest frequency is rank 3, and the rank value of rank 3 can be set to the middle value of the rank.

According to another embodiment of the present invention, the representative value calculation unit 113 calculates a frequency distribution of parameters or attribute values of points in the target area 30, 30 ' The average of the parameter or attribute value of the point belonging to the class can be determined as the representative parameter or the representative attribute value of the target area (30, 30 ').

For example, referring to the frequency distribution shown in FIG. 7, the representative value calculation unit 113 calculates an average of parameters or attribute values of the points at points belonging to the class 3 having the highest frequency, The average may be determined as a representative parameter or a representative attribute value of the target area (30, 30 ').

Then, the design load calculation unit 114 may calculate the design load on the structure based on the representative parameter or the representative attribute value of the target area 30, 30 '.

According to an embodiment of the present invention, the design load calculation unit 114 may use a representative parameter of the target area 30 or 30 'as a parameter for calculating a design load for the structure. That is, the design load calculating unit 114 may use the representative parameters of the target area 30 and 30 'as parameters as they are during the calculation of the design load for the structure.

According to the embodiment, instead of immediately applying the representative parameters of the target areas 30 and 30 'to the design load calculation, the design load calculation unit 114 compares the representative parameters with a predetermined plurality of parameter reference ranges A value corresponding to the parameter reference range to which the representative parameter belongs may be used as the parameter among the plurality of parameter reference ranges.

For example, according to the architectural structure standard (KBC), the basic wind speed used for calculating the wind load is determined to be a multiple of 5, while the basic wind speed of the target area 30, 30 ' When calculating the representative parameter, the value may not be a multiple of 5.

In this case, the design load calculation unit 114 compares the representative parameters calculated through the statistical processing with a predetermined plurality of basic wind speed reference ranges, The corresponding representative basic wind speed can be used as the basic wind speed when calculating the design load for the structure.

For example, when the representative parameter obtained by statistically processing the basic wind speeds of the points in the target area 30, 30 'is 27 m / s and the reference range for the basic wind speed is set as shown in the following table, The basic wind speed of the regions 30 and 30 'can be determined to be 30 m / s, which is the representative basic wind speed of the reference range to which 27 m / s belongs.

Representative basic wind speed (m / s) 25 30 35 Reference range 25 m / s or less Greater than 25 m / s
30 m / s or less More than 30 m / s

In this way, the design load calculation unit 114 applies the representative parameters of the target area 30, 30 'as it is as a parameter to the design load calculation for the structure or compares it with a predetermined reference range, The value assigned to the reference range to which the parameter belongs can be used as a parameter in the design load calculation.

According to another embodiment of the present invention, the design load calculation unit 114 may obtain the parameters used for the design load calculation for the structure from the representative attribute values of the target areas 30 and 30 '.

According to this embodiment, the design load calculation unit 114 compares the representative attribute value with a predetermined plurality of parameter reference ranges, and determines a parameter corresponding to the reference range to which the representative attribute value belongs Can be used as a parameter in calculating the design load for the structure.

As described above, the attribute value is a value used to calculate a parameter used in the design load calculation. The design load calculation unit 114 calculates a representative attribute value of the target area 30, 30 ' It is possible to obtain a parameter corresponding to the representative attribute value by comparing with the reference range.

For example, according to the Building Structure Standard (KBC), a parameter called a terrain factor among the parameters used in the wind load calculation can be determined based on the property value of the windward side slope. According to the above embodiment, the design load calculation unit 114 compares the representative windward-side inclination of the target area 30, 30 'calculated through the statistical processing with the topographic coefficient reference range as shown in the following table, The terrain coefficient corresponding to the reference range to which the representative windward slope belongs may be used as the terrain coefficient parameter during the design load calculation for the structure.

Topographic coefficient 1.1 1.2 1.4 1.6 Reference range 0.05 or more
Less than 0.1 0.1 or more
Less than 0.2 0.2 or more
