摘要

方钢管混凝土异形柱结构是一种新型结构，在汶川县映秀镇渔子溪村重建项目的200余户住宅中得到应用。对此结构进行了较为全面的抗震性能分析，包括阵型分解反应谱分析、弹性时程分析和静力弹塑性分析，并将其静力弹塑性分析结果与单根方钢管混凝土柱结构的结果进行比较。分析发现，方钢管混凝土异形柱结构能够满足抗震要求，且在罕遇地震作用下的表现优于方钢管混凝土单柱结构

Abstract

Special-shaped concrete filled square steel tubular (SCFT) structure，a new type structure, was adopted in wenchuan reconstruction project which includes 200 houses. In order to study the seismic performance of SCFT, several analysis methods such as response spectrum analysis, linear time history analysis and push-over analysis are used. Concrete filled square steel tubular (CFT) structure modal is also analyzed. The analysis results indicate that the SCFT structure meet the seismic demand and the performance of it is better than CFT in rarely met earthquake.
