钢筋砼框架结构抗震控制研究

在分析钢筋砼框架结构实际受力特征的基础上，从结构控制的角度出发，本文提出了允许框架柱下端出现塑性铰的新型延性框架结构方案。通过对延性框架与普通框架结构的非线性全过程分析、弹塑性动力分析和振动合模型对比试验，研究了其受力过程、动力特性、地震反应和破坏形态。结果表明，延性框架结构具有良好的延性和抗震性能。

Seismic Control Research on RC Frame Structures

Based on the investigations on mechanical properties of RC frames,a new kind of ductile frame structure, which allows plastic hinges to occur at the low ends of its columns,was introduced in this paper.Through the comparison of the full course nonlinear analysis as well as the elasto-plastic dynamic analysis and the model tests on shaking table for ductile frames and ordinary frames,the process of load bearing,the dynamic characteristics,the earthquake response and the failure models of these two kinds of frames have been studied.The research shows that the ductile frame has better ductility and seismic behavior than those of the ordinaryframe.
