某复杂高层振动台模型试验测试仪器及试验结果分析

Equipments and Results' Analysis of Shaking Table Model Test for A Complex Supertall Building

某复杂超高层塔楼,结构高度250 m,层数53层。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。按业主委托对其进行了整体结构模型模拟地震振动台试验。本文主要对振动台模型试验过程中所使用的测试仪器及试验结果进行分析,并给出一定结论。旨在为今后类似的结构试验提供参考。

The height of the supertall 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. A shaking table model test was carried out according to owner＇s commission. In this paper, test equipments and test results were analyzed and some conclusions were given. The method applied in this model test will be helpful to other similar experimental studies.
