摘　　要：通过对一榀钢筋混凝土扁梁框架和一榀预应力混凝土扁梁框架的拟动力试验及有限元软件分析,对它们的试验结果及地震反应进行了对比.结果表明:预应力框架结构更能满足"小震不坏、中震可修、大震不倒"的设防标准,即预应力混凝土框架结构的总体抗震性能强于普通钢筋混凝土框架结构.Using the pseudo-dynamic test and the finite element method with the software, we analyze the difference of the reinforced concrete flat-beam frame and the pre-stressed concrete flat-beam frame. The results show that the prestressed frame structure is better to satisy security standards： No damage after a small scale quake, repairable after a medium scale quake and no collapse in a large scale quake. Namely the pre-stressed frame structure＇s overall seismic performance is better than the reinforced concrete structure.
