高位转换框支剪力墙高层建筑抗震性能研究

Seismic behavior analysis of a high-rise building of frame-shear wall structure with high transfer floor

本文通过对一个1:25比例的高位转换框支剪力墙结构高层建筑模型的模拟地震振动台试验,分析研究了高位转换高层建筑的自振特性、阻尼比、地震反应特征、破坏形态和破坏机理。应用三维有限元程序对结构的抗震性能进行了深入探讨,试验与计算值符合较好。成果可供高位转换结构设计和编制有关规程时参考。

Based on the shaking table test of a 1∶25 scale model of high rise building of frame-shear wall structure with high transfer floor, the dynamic properties, damping ratios, seismic responses, damage feature and cracking pattern of model were recorded and analyzed. The seismic behavior of high-rise building with high transfer floor that exceeds the limitation of current design code is discussed using three dimensional finite element analysis programs. Comparing with the measurement results, the calculating values agree fairly well. The viewpoints offered in the paper can be referred in structural design of high-rise building with high transfer floor and in corresponding code compilation.
