  In addition, in the calculation of the floor response in the target floor in the indoor damage video display system according to the present embodiment, the above method was used. However, in the indoor damage video display system according to the present invention, the floor response as described above is used. It is not limited to the calculation example. As another floor response calculation method, for example, response analysis is performed when earthquake motion is input to a plurality of buildings having different total floor numbers, and the floor responses of each floor in each building are stored in advance as a table. In addition, the floor response on the target floor may be obtained by referring to this table. Alternatively, the target building may be modeled in a relatively simple form, and the floor response of the target floor when the earthquake motion is input by this model may be calculated.

Returning to the main flowchart of FIG. 2, in step S104, the damage corresponding to the calculated floor response is selected from the damage patterns stored in the damage pattern storage unit 21 based on the floor response calculated in step S103. A process of selecting a pattern is executed. The damage pattern storage unit 21 stores a damage pattern corresponding to a predetermined maximum floor response acceleration A _f (cm / s ² ) and a maximum floor response speed V _f (cm / s). The data structure of the damage pattern storage unit 21 is as shown in FIG. 8, for example. Here, the table stored in the damage pattern storage unit 21 will be described in more detail.

  The damage pattern storage unit 21 calculates and tabulates in advance in what pattern each of the plurality of indoor installations falls and moves according to a predetermined floor response. In this specification, a combination of damage patterns of a plurality of indoor installations is referred to as a “damage pattern data set”. In order to create the damage pattern storage unit 21, it is necessary to determine what kind of damage pattern data set the floor response will have. A routine for this is damage pattern data set calculation processing. FIG. 4 is a flowchart of damage pattern data set calculation processing in the indoor damage moving image display system according to the embodiment of the present invention.

  Damage pattern data is a parameter used to indicate the level at which indoor installations such as furniture and fixtures move or fall down with floor response. In the set calculation processing subroutine, the damage pattern data of each installation in the room (in the example in this embodiment, three installations of furniture A, furniture B, and furniture C are assumed) is calculated, and all the installations are calculated. A process for obtaining a damage pattern data set including the damage pattern data is performed.

  FIG. 4 (A) shows the flow of the damage pattern data set calculation processing subroutine, and FIG. 4 (B) shows an indoor installation that stores dimension data of indoor installations such as furniture and fixtures that display motions due to earthquakes. It is a dimension table. Each data stored in the indoor installation object size table shown in FIG. 4B is referred to in step S202.

In FIG. 4A, when the damage pattern data calculation process subroutine is started in step S200, a loop process constituted by steps S201 to S208 is executed. In this loop process, a loop process for comprehensive calculation is executed while changing the values of the maximum acceleration A _f of the floor response and the maximum speed V _f of the floor response stepwise.

  In step S202 during the loop process, each dimension data in the indoor installation dimension table shown in FIG. 4B is acquired. As shown in FIG. 4B, the dimension data of the indoor installation includes the height h of the center of gravity of each indoor installation, the length b half the depth, and the coefficient of friction with the floor. .

In step S203, the fall limit acceleration A _o and the fall probability 5 based on the acquired values.
A calculation process of 0% acceleration A _r and slip acceleration A _s is performed, and an area (I) and an area as shown in FIG. 5 are based on the calculated fall limit acceleration A _o and the fall probability 50% acceleration _Ar . (II) and region (III) are set. In FIG. 5, it is possible to appropriately set which region includes the boundary of each region.

FIG. 5 is a chart for determining a damage pattern due to a fall. The boundaries of the boundaries of the respective areas are a fall limit acceleration A _o and a fall probability 50% acceleration _Ar . In the chart of FIG. 5, the horizontal axis is F _e (= A _f / (2πV _f )), and the vertical axis is the maximum acceleration A _f of the floor response. In the chart of FIG. 5, when the floor response of the target floor exists in the region (I), it can be determined that there is no damage situation due to the fall of the indoor installation and is stable, and the floor response of the target floor is When it exists in the area (II), it can be determined that there is some damage caused by the fall of the indoor installation, and when the floor response of the target floor exists in the area (III), it is caused by the fall of the indoor installation. It can be determined that the damage situation is large.

Hereinafter, mathematical formulas for calculating the fall limit acceleration A _o , the fall probability 50% acceleration A _r , and the slip acceleration A _s will be given. In step S203,

The fall probability 50% acceleration _Ar is calculated. However, F _e (variable), F _b (constant), and F _b ′ (constant) are determined by the following equations (20) to (22).

In addition, h is the height of the center of gravity of the indoor installation such as furniture (in cm), b is half the depth of the indoor installation (in cm), and _Af is the maximum acceleration of the floor response (cm / s ² ). , V _f is the maximum floor response speed (cm / s), and g is the gravitational acceleration (cm / s ² ).

  Returning to FIG. 4, in step S <b> 204, a subroutine for individual installation object determination processing is executed. With reference to FIG. 6, the subroutine for the individual installation object determination process will be described. According to this subroutine, the damage pattern due to each indoor installation is determined. FIG. 6 is a view showing a flowchart of a subroutine of the individual installation determination process in the indoor damage video display system according to the embodiment of the present invention.

In FIG. 6, when the subroutine for the individual installation object determination process is started in step S300, it is subsequently determined in step S301 whether A _o > A _s . In this step, it is determined whether the installation object is easy to fall over or easy to move. When the installation object has a large tendency to fall, the determination in step S301 is YES and the process proceeds to step S302. On the other hand, when the installation object has a large movement tendency, the determination in step S301 is NO and the process proceeds to step S307.

  In step S302, it is determined whether or not the floor response exists in the region (I) in the chart of FIG. When the determination in step S302 is YES, the process proceeds to step S306, and it is assumed that the installation object is stable and the damage pattern is 1 even by a floor response. On the other hand, when the determination in step S302 is NO, the process proceeds to step S303.

  In step S303, it is determined whether or not the floor response exists in the region (II) in the chart of FIG. When the determination in step S303 is YES, the process proceeds to step S305, where there is a possibility that the installation object may fall over and the damage pattern is 4. When the determination in step S303 is NO (when the floor response is present in the region (III) in the chart of FIG. 5), the process proceeds to step S304, the fall damage caused by the installation is large, and the damage pattern is 5 Suppose that

  In step S307 which proceeds when the movement tendency of the installation object is large, the movement amount δ is calculated by the equation (24). In step S308, it is determined whether or not δ> 5 (cm). When the determination in step S308 is NO, the process proceeds to step S312, and the installation object is stable and the damage pattern is 1 by the floor response. On the other hand, when the determination in step S308 is YES, the process proceeds to step S309.

In step S309, it is determined whether or not δ> 50 (cm). When the determination in step S309 is NO, the process proceeds to step S311, and it is assumed that there is a possibility of movement damage due to the installation object, and the damage pattern is 2. When the determination in step S309 is YES, the process proceeds to step S310, and it is assumed that the movement damage due to the installation object is large and the damage pattern is 3.

  In step S313, the process returns and returns to the original routine.

Returning to the flow of FIG. 4, in step S205, the calculated damage pattern value is added to the damage pattern data set. FIG. 7 is a diagram showing a data structure example of a damage pattern data set in the indoor damage moving image display system according to the embodiment of the present invention. As shown in FIG. 7, if the calculated damage pattern value is for furniture A, it is the first one in the damage pattern data set, and if the calculated damage pattern value is for furniture B, the damage pattern is If the calculated damage pattern value is that of furniture C, it is assumed that the damage pattern data set is the third one.

In step S206, it is determined whether or not the calculation of the damage pattern has been completed for all the installed objects. When the determination in step S206 is NO, the process proceeds to step S207, loops to calculate the damage pattern of the next furniture, and when the determination is YES, the process proceeds to step S208. In step S208, the maximum acceleration A _f of all floor responses.
When the combination of the maximum floor response speed _Vf is completed, the process exits the loop, proceeds to step S209, and ends the process.

  By the damage pattern data set calculation process as described above, it is possible to determine what kind of damage pattern data set is generated at the time of floor response, and based on this, the damage pattern storage unit 21 shown in FIG. It is possible to create a table to be stored.

  Returning to the main routine shown in FIG. 2, in step S105, moving image data corresponding to the obtained damage pattern data set and earthquake type is acquired.

Here, in the indoor installation dimension data stored in the indoor installation dimension table shown in FIG. 4B, for furniture A, h _a = 97 (cm), b _a = 45 (cm), μ _a = 0.
3. For furniture B, h _b = 89 (cm), b _b = 70 (cm), μ _b = 0.1,
For furniture C, h _c = 15 (cm), b _c = 7.5 (cm), and μ _c = 0.3. In this case, the range of the maximum acceleration A _f of the floor response 0-1000, also, the maximum velocity V _f of the floor response and varied from 0 to 140, the damage pattern data set determining process described with reference to FIG. 4 Accordingly, the damage pattern data set takes values as shown in FIG. FIG. 8 is a diagram showing an example of the data structure of the damage pattern storage unit 21 in the indoor damage video display system according to the embodiment of the present invention.

According to the calculation example of the damage pattern data set as shown in FIG. 8, for example, the damage pattern data set for the floor response in which the maximum acceleration is 50 <A _f ≦ 100 and the maximum speed is 10 <V _f ≦ 20 is The damage pattern data set for a floor response with (1,1,1), maximum acceleration 100 <A _f ≦ 150, and maximum speed 130 <V _f ≦ 140 is (1,1).

  The patterns that the damage pattern data set in FIG. 8 can take are (1, 1, 1), (1, 2, 1), (1, 2, 4), (1, 2, 5), (2, 2, 2), (2,2,5), (4,1,4), (4,2,4), (4,2,5), (4,3,4), (5,2,4) , (5, 2, 5), (5, 3, 4), and (5, 3, 5).

In addition, for one damage pattern data set, there are two video data indicating the damage status in the room, one for a direct earthquake and one for a long-distance earthquake. It is sufficient to prepare 28 patterns of moving image data that is twice the 14 patterns.
