摘　　要：基于UPPC梁的低周反复加载试验,并通过有限元ABAQUS对UPPC梁的模拟分析,较为系统地研究了自控耗能UPPC梁与普通UPPC梁的变形恢复能力、耗能能力、延性及承载力等抗震性能。研究表明:自控耗能UPPC梁的变形恢复能力、延性、耗能能力均高于普通UPPC梁,可较好地解决普通UPPC梁在地震作用下存在的变形能力较差,耗能不足等问题;另外,自控耗能UPPC梁承载力稍低于普通UPPC梁,说明自控耗能UPPC梁易于形成梁铰机制,更符合抗震要求。The low reversed cyclic loading experiment and finite element analysis of self-adapting energy and common UPPC beams are carried out to investigate seismic performance,such as displacement restoring,energy dissipation capacity,ductility,failure patterns,etc. The studies show that the self-adapting energy UPPC beams is better than the common UPPC beams in displacement restoring,energy dissipation capacity,ductility. The results can help us solve the problem of poor energy dissipation capacity and lack of displacement restoring. Besides,the bearing capacity of self-adapting energy UPPC beams is worse than the common UPPC beams in failure patterns. It reflects that the self-adapting energy UPPC beams is easy to form beam hinge mechanism,and to meet seismic requirements
