高位转换超高层整体结构振动台试验设计

同济大学土木工程防灾国家重点实验室对上海某带高位转换超高层结构进行了整体结构模型模拟地震振动台试验.该超高层塔楼53层,结构高度250 m,采用型钢混凝土框架-钢筋混凝土筒体结构,设有加强层及竖向主要受力构件高位转换层.在高位转换超高层结构体系、振动台试验模型材料的选取、动力相似关系的确定以及试验方案的设计等振动台试验的前期工作方面,进行了详细的阐述.所介绍的模型设计思路及制作过程,为今后的有关试验工作提供了一定的参考.

Test Design of a Shaking Table Model for a Super Tall-Building with High Level Transfer Storey

A shaking table test was carried out for a 53-storeyed super tall-building with high level transfer storey in State Key Laboratory for Disaster Reduction in Civil Engineering at Tongji University.The height of the super tall-building is 250 m above ground,and the central RC tube and peripheral SRC frame with two outrigger trusses are employed to resist vertical and lateral loads.This paper mainly focuses on the design work for shaking table model test and illustrates the structural system characteristics of the super tall-building in detail, model material selection,similitude-scaling relationship and design of test program.The method of model design and making process recommended in this paper are feasible in the test.The method applied in model and test program design of this super-tall building will be helpful to other experimental studies.
