가새를 설치한 조립식 스틸 구조의 반응수정계수 평가

Abstract

The purpose of this study is to evaluate the performance of cold-formed steel (CFS) frames with shear panels designed under current U.S. design codes and standards of practice. The response modification factor, R, of the cold-formed steel structural system was examined using the rational approach proposed by Foutch and Wilcoski. The approach is based on the performance evaluation method developed from the SAC project. The target is to achieve a 90% confidence level in satisfying the Collapse Prevention(CP) performance level for a hazard level with 2% probability of being exceeded in 50 years. New values for various parameters were decided for CFS buildings because parameters from SAC project were for steel moment frame buildings.
