钢筋混凝土核心筒体抗震性能分析

Seismic analysis of reinforced concrete core wall by finite element method

本文在非线性有限元计算模型和分析程序的基础上,对影响钢筋混凝土核心筒体抗震性能的三个重要参数,即高宽比、轴压比、连梁刚度比,进行了一系列模型的非线性计算分析,得出了各参数对核心筒的承载力、破坏形式、延性、耗能能力等抗震性能的影响,为参数影响的定量研究和工程设计提供了有价值的参考。

On the basis of a nonlinear reinforced concrete finite element analysis model and an analysis program, the behavior of reinforced concrete core walls under cyclic loads with different axial load ratio, different heightwidth ratio and different coupledbeam stiffness was studied. The comparison of the experimental and computational results shows that the analysis model is reasonable. And the effects of the parameters were also studied.
