In order to support earthquake disaster BCP, the authors proposed a simple dynamic earthquake resistance evaluation method using basic information of the building, which consists of a method of estimating the load capacity coefficient and a method of predicting the damage to the building structure from the capacity spectrum method for the one-degree-of-freedom building model. However, problems such as verification of the damage prediction accuracy of a simple dynamic seismic evaluation method remained unsolved.
In recent years, environments for verification analysis that include, for example, facility information, earthquake observation records, and damage information have been prepared by publishing various building damage reports and earthquake observation records for buildings affected by the 2011 Great East Japan Earthquake. For this reason, the accuracy of damage prediction by a simple dynamic earthquake resistance evaluation method was verified using public information on 28 buildings.
Although the simple dynamic earthquake resistance evaluation method sometimes gives a slightly higher response value, the resultant damage assessment was for the most part reasonable. It was therefore confirmed that this method is effective as a screening evaluation method in seismic resistance surveys of multiple existing buildings and at the planning stage for earthquake countermeasures.
