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。
Based on the analysis of the actual stress characteristics of reinforced concrete frame structures, and from the perspective of structural control, this paper presents a new ductile frame structure scheme that allows plastic hinges at the lower end of the frame columns. Through non-linear full-process analysis, elasto-plastic dynamic analysis and vibration combined model comparison tests of ductile frames and common frame structures, the stress process, dynamic characteristics, seismic response and damage patterns were studied. The results show that the ductile frame structure has good ductility and seismic performance.
