JP 2003-147970 A

The seismic performance evaluation value such as Is value is a value obtained by the product of the strength and toughness of the building, and is a so-called “structural seismic index” that represents the risk of the building collapsing against earthquake vibration and impact. Become one of the standards.
According to the notification of the Ministry of Construction on December 25, 1995, the general standard for Is value is as follows: “If the Is value is less than 0.3,“ There is a high risk of “collapse”, with an Is value of 0.3 or more and less than 0.6, there is a risk of “collapse or collapse” with respect to earthquake vibration and shock. "The risk of collapsing or collapsing" is low with respect to vibration and shock.
Since these indices are obtained by the product of the strength and toughness of the building as described above, as shown in FIG. 7, the solid line L on the graph has toughness F on the horizontal axis and strength C on the vertical axis. Can show. That is, on the solid line L evaluated with the same Is value, there are various types of buildings ranging from high strength and low toughness buildings to low strength and high toughness buildings. Even in this case, the evaluation is performed with the same Is value.
According to the conventional seismic performance evaluation technology described above, the seismic retrofit cost is calculated based on the calculated seismic performance evaluation value. The same damage situation will be set for low-toughness buildings and low-strength, high-toughness buildings, and restoration costs will be calculated in the same way.
However, even if the buildings are evaluated with the same Is value, the high-strength and low-toughness buildings tend to have smaller swing angles than the low-strength and high-toughness buildings, and there is a considerable difference in the damage situation between the two buildings. There is. In particular, the damage situation of the non-structural members such as the outer wall curtain wall member, the opening sash member, the inner wall partition board, and the ceiling member is greatly different. Therefore, there is a big difference between the two buildings in terms of restoration costs. The restoration costs required by the conventional seismic performance evaluation technology are difficult to match the current situation, and there is a problem that the calculation accuracy of building assessment is low.

Accordingly, an object of the present invention is to solve the above problems, is to provide a seismic performance evaluation system capable of performing a seismic performance evaluation with higher accuracy.

According to a first characteristic configuration of the present invention, a recordable building information database is provided by inputting building information for determining an earthquake resistance evaluation value of a building to be evaluated by an input means, and the building information in the building information database is stored in the building information database. In the seismic performance evaluation system provided with the first calculation means for determining the seismic performance evaluation value of the building to be evaluated based on the damage status corresponding to the interlayer deformation angle at the time of earthquake for each non-structural member used in the building Second calculation means for calculating an interlayer deformation angle at the time of the earthquake of the evaluation target building by providing a database for predicting non-structural member damage that is set and recorded in advance and inputting the strength of the evaluation target earthquake The non-structural member is provided for each non-structural member used in the building to be evaluated based on the interlayer deformation angle determined by the second calculating means. Assign a damage situation from harm expected database, they third arithmetic means for the restoration costs for each non-structural members to aggregate and calculated separately is provided, on the respective non-structural member used in the evaluation target building There is provided a list creation means for freely creating a damage status list in which the damage status can be written freely .

According to the first characteristic configuration of the present invention, the nonstructural member damage prediction database in which the damage situation corresponding to the interlayer deformation angle at the time of the earthquake is preset and recorded for each nonstructural member used in the building is recorded. A second calculation means is provided for calculating an interlayer deformation angle at the time of the earthquake of the evaluation target building by inputting the strength of the earthquake to be evaluated, and the interlayer deformation determined by the second calculation means Based on the corners, assign damage status from the database for damage prediction of non-structural members for each non-structural member used in the building to be evaluated, and calculate and aggregate the restoration costs for each non-structural member separately. Since the 3rd calculating means to be provided is provided, it becomes possible to perform a more accurate earthquake-resistant performance evaluation.
The second calculation means can calculate the interlayer deformation angle of the building accompanying the earthquake, and the third calculation means can calculate the damage status of each non-structural member corresponding to the interlayer deformation angle for non-structural member damage prediction. It is possible to calculate the restoration cost of the non-structural member by assigning each from the database.
In other words, since the damage status setting of non-structural members when the evaluation target building is in an earthquake is performed based on the interlayer deformation angle at the time of the earthquake, evaluation in a state close to actual building deformation can be performed. It becomes possible. Therefore, as in the past, if the buildings have the same Is value, the problem that the damage situation of the non-structural members is the same regardless of the ease of shaking can be solved. It is possible to evaluate that the damage situation of the non-structural member becomes larger than that, and it is possible to perform a more realistic seismic performance evaluation.

In addition, by pre-Symbol list means it is possible to create the damage situation list. In addition to being able to use this list as a simple writing list, for example, when an earthquake actually occurs and damage is caused to the building to be evaluated, bring this damage status list to the affected area and list the damage status in each column one after another. It is possible to quickly and efficiently create a document for understanding the actual damage situation by writing.
In addition, in each non-structural member column of the damage status list, in addition to a space for writing the damage status (actual measurement column), a space (prediction column) in which the damage expected status obtained from the interlayer deformation angle is described in advance can be provided. If the current situation is the same as the print contents when writing the current damage situation (see FIG. 6), there is no need to describe it in detail, and it becomes possible to collect situation grasping materials more quickly. Therefore, it is possible to accurately and quickly record the damage status of each non-structural member even in a confused disaster-stricken environment, and it is possible to accurately determine the restoration cost based on the data.
