| 摘 要： | 通过低周反复荷载试验对两榀双层双跨高性能混凝土框架的破坏形态、破坏机制、滞回曲线、骨架曲线、恢复力模型、变形恢复能力、位移延性、刚度退化、耗能能力等性能进行了较为深入系统的研究。研究表明 ,非预应力高性能混凝土框架和中等预应力度的预应力高性能混凝土框架均具有良好的抗震性能。基于非线性有限元原理 ,编制了多层多跨高性能混凝土框架基于恢复力模型的滞回全过程分析程序 ,应用该程序对本试验结果进行了模拟计算 ,计算值与试验结果吻合较好

| Abstract: | The seismic performance such as failure pattern,fai lure mechanism,hyst eresis loop curves,restoring-force model,displacement-restoring capacity,displac ement ductility,rigidity degradation and energy dissipation of two pieces of HPC frame with double-story and double-span are studied systematically by testing o f low reversed cyclic loading.It was shown by studied that seismic performance o f both the ordinary HPC frame and the moderate prestressed HPC frame with modera te PPR are better. Analyzing program on full process of hysteresis loop of the HPC frame with mult- story and mult-span HPC frame is developed based on nonlinear FEM.Calculations b y this program are in good agreement with the testing results. |
