同济大学土木工程防灾国家重点实验室对上海某立面收进超高层建筑进行了整体结构模型模拟地震振动台试验。该超高层建筑共58层,结构高度244.8 m,采用型钢混凝土框架-钢筋混凝土筒体结构体系并设有斜柱和加强层,结构在141.9 m处有较大的立面收进。主要介绍了该结构模型振动台试验设计过程,包括模型材料的选取、模型相似关系的确定、模型简化与设计、试验方案的确定以及试验前的各项准备工作,并对其中存在的问题进行了讨论,所提供的高层建筑模型振动台试验设计思路和过程也可以为今后相关的试验工作提供一定的参考作用。
A shaking table test was carried out for a 58-storeyed super high-rise building with elevation setback in State Key Laboratory for Disaster Reduction in Civil Engineering at Tongji University. The structural height of this building is 244.8 m above ground. The building with elevation setback in the height of 141.9 m has RC core and SRC frame structural system and contain inclined columns and strengthened stories. In this paper, the shaking table model test design is introduced in detail including model material selection, similitude relationship determination, model simplified design, test program design and other preparation work and the questions in this test are also discussed. The method applied in model and test program design of this super high-rise building will be helpful to other experimental studies.
