| 摘 要： | 本文通过一榀无粘结预应力混凝土门架结构和一榀普通通钢筋混凝土门架结构在低周反复荷载荷的试验，对预应力混凝土门架的抗震性能进行了 试验研究；在此基础上，编制了预应力混凝土门架结构的非线性分析程序，本程序实现了包括下降段在内的滞回全过程计算，计算值与试验结果具有良好的似合性。本文结果为预应力混凝土门架结构在地震区的推广应用提供了依据和参考。

| Abstract: | Based on experiments of one unbonded P.C.portal structure and one R.C.portal structure under low reversed cyclic loading,analysis and research on seismic behavior of P.C.portal structures were carried out,In addition,Program,which was capable of full-range hysteresis analysis of P.C.portal structures,including descending part, was developed in this paper.Calculations were in good agreement with experimental results.This paper can provide verifications and references for application of P.C.portal structures in seismic area. |
