STUDY ON APPROXIMATE ESTIMATION METHODS FOR LATERAL STRENGTH OF GYMNASIUM BY GUIDELINES OF SEISMIC DIAGNOSIS

Abstract

Occasionally, in seismic retrofitting, the lateral load-carrying capacity is approximately estimated according to the guideline for the seismic diagnosis of gymnasiums. The approximate estimation method is very simple and useful for structural engineers. However, this method needs further refinement. Under the condition that large long-term primary load is applied, for example in regions with heavy snowfall, the position of plastic-hinges is different from that assumed in guideline.
The purpose of this study is to propose a new set of considerations for the approximate estimation methods that use the guideline for the seismic diagnosis of gymnasiums.
