摘要:
本文根据八榀钢筋混凝土门式刚架不变竖向加载和单调水平加载的试验资料,归纳了截面屈服曲率和极限曲率的经验公武,提出了截面曲率延性系数和框架单元位移延性系数与强度的计算公式。此外,还讨论了加载过程中钢筋混凝土刚架杆端塑性饺的性能,给出了计算等效塑性铰长度的经验公式。文中所提出的公式均与试验结果符合较好。
Abstract:
From the experimental results of eight models of RC portal frames subjected to constant vertical and monotonic horizontal loading, empirical formulas representing the yield curvature and ultimate curvature of section are given. Formulas for calculating the curvature ductility factor of section, displacement ductility factor and strength of frame are presented. Besides, the behaviour of plastic hinge at the member end of RC frame in process of loading is discussed and the empirical formula for calculating the equivalent length of plastic hinge is also given. The presented formulas are in good agreement with the experimentai results.
