摘要
本文对超薄壁型轻钢结构多层住宅结构体系的分析研究,主要在一榀平面框架模型基础上,建立相应的质点动力计算简图和计算方法,同时着重分析了考虑蒙皮效应的超薄壁型轻钢结构在地震等动力荷载作用下的受力影响情况,包括结构振型、周期、位移、内力等动力特性及地震的时程响应行为,并与未考虑蒙皮效应的超薄壁型轻钢结构进行了对比分析研究,得出的有限元分析模型对以后的理论分析有一定的借鉴作用,并对工程实际应用提供较为可靠的理论依据。
Considering shear-resistant membrane of the very thin-walled light-gauge steel structural multiple story dwelling in the paper, mainly based on a plan frame,the calculating simple figure and method are presented. And the very thin-walled light-gauge steel structure is analyzed in the dynamic load such as earthquake etc., including its vibration mode, period, displacement, internal force and seismic time history response.These are compared with that without considering shear-resistant membrance. The finite element model found is available in the theoretical analysis in the future and can provide reliable theoretical principle in the practical engineering.
