短肢剪力墙筒体结构模型振动台试验研究

显研究短肢剪力墙－筒体结构体系的抗震性能，采用数种地震波形，对一栋采用这种结构体系的30层高楼模型（缩比为1／20）进行了模拟多种烈度地震振动台试验。试验数据经处理后，获得了加速度、动力放大系数、位移以及不同烈度地震作用下结构振型的变化。试验结果表明，该体系不仅使用性能好，而且具有良好的抗震性能，是一种很值得在7度地震区、20－30层高层住宅建设中推广采用的结构体系，同时中对该体系的设计方法提出了进一步改进的建议。

Earthquake Simulation Test of Short-Leg Shear Wall-Tube Model

In order to research on the earthquake resistance behavior of the short leg shear wall tube structure system, a 1/20 scale model of this structure was constructed and tested on the shaking table with several earthquake waves.The structure responses such as acceleration, dynamic magnification, displacement and the variation of vibration modes at different elastoplastic stages were obtained by data processing. The test results show that this kind of structure system is possessed of good earthquake resistance and satisfactory service performance. So it is worthy of extending its application to tall residential buildings with 20-30 stories in seven degree earthquake zones. Meanwhile some suggestions for further improving the design are presented.
