摘要

本文对预应力组合梁框架的抗震性能进行试验研究与滞回分析。基于预应力组合梁框架的低周反复荷载试验,对其破坏形态、破坏机制、位移延性、耗能能力、刚度退化、变形恢复能力等抗震性能进行了较为系统的研究。研究表明预应力组合梁框架具有优良的抗震性能。编制了预应力组合梁框架滞回分析程序,探索了预应力组合梁框架理论分析的新途径。
It is the first time that experimental studies and hysteretic analysis on seismic performance of frames with prestressed steel concrete composite beams are carried out in China and abroad. Based on experiments of two frames under low reversed cyclic loading, the failure pattern, failure mechanism, displacement ductility, energy dissipation, rigidity degeneration and deformation restoring behavior, etc. have been systematically studied, showing that frames with prestressed steel concrete composite beams have good seismic performance. In addition, programs capable of hysteretic analysis of frames with prestressed steel concrete composite beams have been developed in this paper, which provide a new way to analyze such frames with prestressed steel concrete composite beams.
