Abstract

School facilities are the center of a local community; due to its role, it is progressing most rapidly in promoting seismic reinforcement projects for public facilities. In accordance with the School Facility Seismic Performance Evaluation and Reinforcement Manual, a school facility seismic reinforcement project is primarily determined through a linear analysis evaluation method and the project is terminated if it is evaluated to have seismic performance. In the case of existing school facilities with shear walls, there were cases where it was considered to have seismic performance due to shear walls with excellent lateral resistance performance during a linear analysis evaluation. However, in some of these cases, detailed analysis of the weak shear wall had not been conducted due to the controlling strength ratio calculated by the arithmetic mean. This study analyzed the limitations of the governing strength ratio calculated by the existing arithmetic mean and proposed a method to calculate the governing strength ratio by considering the possibility of power redistribution and destruction of components to supplement for these limitations.
