摘要
Websteel轻钢龙骨结构体系是一种轻质、节能、环保且施工快捷、方便的冷弯薄壁型钢结构体系,适用于低、多层建筑。为了解该结构体系的动力特性及抗震性能,对该体系两层足尺房屋模型进行振动台试验,研究结构在不同输入波、不同烈度水准下的地震响应。采用有限元方法对该结构模型进行动力计算分析,并与试验数据进行对比。有限元分析与试验结果基本一致,表明分析方法的有效性,为该结构体系的计算、设计提供了相关数据和参考。
WEB light-gauge steel system is simply called websteel, which is a new kind of cold-formed thin walled steel structures. It has many advantages, such as lightweight, energy-saving, environmental protection and convenience to construct, and suitable for low or multi-story buildings. To investigate its dynamic characteristics and seismic performances, a shaking table test for its full size 2-story house was carried out. The seismic responses of structure under different levels of earthquake are studied. The dynamic analysis is performed using FEM to verify the shaking table test results. The results obtained by finite element analysis are identical with the test results. It proves the validity of the analysis, and can be used as a reference for the structural design with this type buildings.
