摘要
上海仙乐斯广场３６层、高１５４ｍ，内筒高宽比为１５，是带有多种转换形式的筒体一框架结构。为了解其抗震性能，进行了整体模型（１／２２）振动台试验。试验结果表明，该结构刚度偏小、位移偏大，地震作用下有明显的扭转效应和顶部的剧烈甩动，并存在抗震薄弱楼层。
A 36 story Shanghai Ciros Plaza of 154m high is a multi transform frame shear wall structure with the high wide ratio of 15 for the inner tube In order to investigate its seismic characteristics,a shaking table test of 1/22 scale model was carried out The experimental results showed that due to its less lateral stiffness,the top displacement could not satisfy the requirement for seismic design Strong torisional and whipping effects happened,and seismic weak story was found during testing
