| 摘 要： | 通过一榀无粘结预应力混凝土门架模型和一榀普通钢筋混凝土门架模型在低周反复荷载下的整体抗震试验，对强柱弱梁型预应力混凝土门架的破坏过程、破坏机制以及变形能力、强度、刚度、延性、耗能能力等性能进行了分析研究；编制了预应力混凝上门架结构的非线性滞回全过程分析程序，计算结果与试验值具有良好的拟合性。本文成果为预应力混凝土门式刚架在地震区的推广应用提供了试验和理论上的依据。

| Abstract: | Based on experiments of one unbonded P. C, portal structure model and one R,C. portalstructure model under low reversed cyclic loading,analysis and research on failure pattern,failuremechanism,deformation,strength,ductility as well as energy dissipation of P,C .portal structures withstrong column and weak beam are carried out,program,capable of full-tange hysteresis analysis of P.C. portal structures,is developed,calculations are in good agreement with experimental results,The ex-perimental and theoretical verifications for application of P,Cportal structures in seismic area are pro-vided. |
