In general, a ramen type consisting of beams and columns is widely used for building structures. Ramen forms have been widely used for some time because of their excellent structural properties.

In such a ramen form, there are various ways of designing beams or representing drawings in different countries. In particular, there is a big difference between the reinforcement method mainly used in Korea and the reinforcement method used in foreign countries. Therefore, even if the design program used in foreign countries for the design of the beam is introduced as it is, there is a limit in applying it to the actual design.

In the structural design of the beam, the method of calculating the rebar amount is simple, but the design of the beam is done by manual table work rather than relying on the program because much judgment of the designer is required.

However, when designing a beam by hand, it takes a lot of time to calculate the cross-sectional force for design, and many errors and errors occur in this process because it is necessary to find the maximum value among many data.

In addition, it takes a lot of time to create the reinforcement list, and moving the reinforcement list to the CAD drawing also requires a lot of errors because it requires manual work, and it is necessary to go through the verification process to correct the error. Effort is taking.

Therefore, the present inventors automatically perform the design of reinforced concrete beams using analysis result data obtained from a conventional structural analysis program or analysis model data therein, thereby increasing the speed and efficiency of the design and preventing errors occurring in the design process. In order to propose the present invention.

It is an object of the present invention to provide a method for automatically designing reinforced concrete beams.

Another object of the present invention is to provide a method of designing a reinforced concrete beam that can prevent errors that may occur when designing a reinforced concrete beam made by hand and increase work efficiency.

The above and other objects of the present invention can be achieved by the present invention described below.

Before and after recombining the beam element list, the beam element is designed by dividing the beam element into a start end (outer end) / end end (inner end); And automatically classifying the selected elements into inner and outer ends collectively, and in the case of automatic division, it is preferable to use the cross-sectional force of the member.

The present invention is to have a function of automatically tying the selected several beam elements into a single beam element, if the automatic bundle is to bundle only the elements that are the same angle of the beam elements and connected in a straight line The bundled beam elements are analyzed by the length and position of each beam element included in the starting point from the start point to the 1/4 position of the span, from the center of the 1/4 position to the 3/4 position of the span and the syrup. The cross-sectional force may be recombined by dividing the end from the 3/4 position to the end point.

The front end face has one input cross section per member, and the front end face has a part for inputting both cross sections and a part for inputting a central part. It is desirable to.

The member type has a function of automatically dividing, and in the case of automatic division, if the ratio of the length of the beam element and the dance of the member is small, it is a shear surface, and if the difference between the cross-sectional force and the required reinforcing amount of each position is small, the same. You can also tie it up.

In the case of automatically classifying the member type, the verification ratio by the positive moment is displayed next to the lower reinforcing bar display portion, the verification ratio by the parent moment is next to the upper reinforcing bar, and the verification ratio by the shear force is displayed next to the shear force output position. Provide convenience.

The present invention, by using the analysis result data of the conventional analysis program or this and the model data together, it is simpler and faster, and can prevent mistakes and errors in the manual design process in the manual operation, and according to the construction situation It provides the function to identify and consider the reinforcing bar connection relation with the adjacent beams and has the effect of inventing the seismic details to be reflected in the design.

Hereinafter, the contents of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall flowchart of a method for designing a reinforced concrete beam according to the present invention.

As shown in FIG. 1, the method for designing a reinforced concrete beam according to the present invention takes an analysis result data analyzed from an existing analysis program, and processes the same as in step S10. This analysis result data uses analysis result data generated from existing well-known analysis programs such as MIDAS, ETABS and neoMAX-3D.

In step S10, a layer group is designated to bundle the analysis result data for each layer group. In other words, an arbitrary layer is bundled and set as one layer group. The injection force window shown in FIG. 2 illustrates the designation of one group from the first floor to the fifth floor. In addition, the process of receiving additional data required for design. Additional input data includes, for example, the strength of reinforcing bars and concrete, the dimensions and covering thickness of reinforcing bars, and the presence or absence of seismic requirements. Data input in this process can be changed during the design process. On the other hand, if the code names of the members belonging to the same layer group are the same, they can be treated as the same member and designed.

Based on the input data, the required rebars are automatically calculated and set as initial values so that they can be used in future designs.

On the other hand, in step S10, after importing the analysis result data, the model data of the analysis program may be imported together, or the cross-sectional force obtained during the design process may be further included.

Next step S11 is a step of recombining the beam elements belonging to the sign of each member. Although it is possible to generate the code element list by code from the analysis program, the process of changing the element list by code in the analysis program is inconvenient, so that it can be directly recombined. In order to conveniently change the list of beam elements by code, it is possible to change by drag and drop on the screen display and update the floor plan by applying the changes in real time to the floor plan display window (see FIG. 4). This allows the user to visually check. At this time, when there are different members among the same element lines perpendicular to the plan view, it is preferable to distinguish them by displaying them with a specific symbol.

In this step S11, before and after the step of recombining the code element list by code, it is possible to designate the inner / outer groups for each element and to make changes possible. In this case, a display for distinguishing the inside / outside may be output together on the plan view display window (see FIG. 4) so that the user can easily recognize the same. The selected elements can be automatically and internally separated in batches, and in the case of automatic classification, they are classified using the cross-sectional force of the member.

In the analysis process, beam elements are divided and used in node units, but in the case of design, they are composed of member (sign) units so that multiple beam elements can be grouped into one beam element. At this time, only the elements having the same member angle among the selected beam elements are bundled into the same element. When bundling a plurality of beam elements into a single beam element, it is preferable to analyze the position of the beam element before bundling so that the cross-sectional force is recombined into the start (outer), center, and end (inner end).

In displaying such a process on the screen, a single injection force window (see FIG. 2), a unit beam information window (see FIG. 3), and a plan view display window (see FIG. 4) that allow input of each variable of each floor group member are provided. It is desirable to provide convenience to the user by displaying on the screen. For example, the injection force window is displayed on the left side of the screen, the unit beam information window is displayed on the upper right side, and the plan view display window is displayed on the lower right side.

This step S11 includes a process of automatically recalculating other data when each data is changed by recombination. Verification ratios of the calculated results are expressed in numbers, but when the verification ratio is less than 1.0, the verification ratio may be visually distinguished, such as blue.

In the unit beam information window (refer to FIG. 3), items such as "element number", "validation ratio", "selected element", and the like are preferably arranged so as to be displayed in alignment with the conditions of the selected item.

By displaying the rebar amount for each position in the plan view output window (see FIG. 4), it is possible to easily check the continuity of the rebar. In addition, in the case of the beam element is divided into the inner end / the center / the outer end of the member type, the inner / outer end of the beam element is displayed in the shape so that it is easy to check the designation status of the inner / outer ends.

The unit beam information window and the plan view output window may be output for each floor. It is also possible to output all selected layer groups. When outputting the entire floor belonging to the floor group from the floor plan output window, if the same beam element is composed of unequal members, it can be easily distinguished by displaying with a specific symbol.

Next step S12 is to set the member type. The member type includes a shear surface that is equally absent throughout the entire section of the member; Both end faces are equally arranged in both sides and the middle part is arranged in different positions; The inner end, center part, and outer end are divided into three types of inner end. In case of the shear surface, there is one input cross section per member (sign), and in the case of both end surfaces, there is a part for inputting both end faces and a part for inputting the central part. It is to separate the input section.

On the other hand, in the present invention, it is possible to automatically set the above three types of member types, in which the automatic setting method using the ratio of the dance of the member and the length of the member, the cross-sectional force of the member and the required reinforcement amount is calculated automatically To set the appropriate one automatically. In addition, when the verification ratio by the positive moment is displayed next to the lower reinforcing bar display portion, the verification ratio by the parent moment is next to the upper reinforcing bar, and the verification ratio by the shear force is next to the shear force output position, it may provide a user's design convenience. Can be.

In one member, the dimensions of the main bar, the size of the shear bar, and the skin bar (abdominal reinforcing bar) may be provided with only one input box. In the input part of each position, the cross section including the reinforcement situation is displayed and the maximum / minimum moment and shear force are output on the upper part.

The input range is designated in the input window, and when the value changed by the user falls within the specified range, it automatically calculates and outputs the verification ratio. Data in the input window may be automatically copied by input of a designated key and moved to the designated position.

In the next step S13, the member is selected according to the designated member type, and the design is performed by automatically calculating the reinforcement of the member selected in the next step S14.

In the next step S15, when the back muscles are designated according to the automatic design, the user can adjust the back muscles. At this time, the reinforcement is adjusted by using the verification ratio, design restriction, rebar amount, and external detailed design function export, and the design for the corresponding code (member) is completed. The process then returns to step S13 to re-design the other members. The process is repeated until the design for all members to be designed is completed.

When the design is completed, the process proceeds to the final output step in the next step S16. The output may be performed in the form of a list output S161 (see FIG. 5), a drawing output S162 (see FIG. 6), and a calculation result report output S163. For example, the output of the list outputs a list of muscles, the output of a drawing outputs a drawing in CAD format, and the calculation result report is output in the form of a summary calculation result report summarizing the final calculation result.

In this case, it is preferable to output the bar list and the drawing output by layer groups, add a prefix before the code name, and output the result list by grouping the same list when the size of the member and the bar are the same.
