摘要
应用OpenSEES有限元软件中带有转动弹簧和剪切弹簧的简化二维节点梁柱单元模型,编制了预应力装配式混凝土框架结构低周往复荷载试验和拟动力荷载试验的计算程序,并对国内研究者已完成的一榀一层两跨的预应力装配式混凝土框架低周往复荷载试验和一榀两层两跨的预应力装配式框架的拟动力荷载试验进行了模拟分析,分别得到了计算的滞回曲线和时程曲线。结果表明:计算曲线与试验曲线吻合良好,可为预应力装配式框架的设计分析提供一种途径。
The author applied the simplified two-dimensional node beam-column element model with rotating spring and shear spring in the finite element software of OpenSEES,and compiled the calculation program of low-cycle reciprocating load test andpseudo-dynamic load test of prestressed concrete frame structure.The low-cycle reciprocating load test of a one-story,two-span prestressed concrete frame and the pseudo-dynamic load test of a two-story two-span prestressed assembly frame have been simulated by domestic researchers.The calculated hysteresis curves and time-history curves show that the calculated curves agree well with the experimental curves,which can provide a way for the design analysis of pre-stressed fabricated frames.
