CALCULATION METHOD OF DESIGN SEISMIC LOADS FOR RC GYMNASIUMS WITH STEEL ROOFS BY RESPONSE SPECTRUM ANALYSIS USING GROUND ACCELERATION

Abstract

During major earthquakes, many damages were reported to RC gymnasiums with steel roofs. Previous studies have proposed methods to control the out-of-plane response, which is the main cause of damage. However, a method for calculating the design seismic loads that considers the vibration characteristics of the entire structure, including the out-of-plane response, has not yet been proposed. Therefore, in this paper, we propose a method to calculate the design seismic loads for RC gymnasiums with steel roofs by the response spectrum analysis using ground acceleration.
