摘　　要：高强混凝土置换截面法是结构直接加固法的一种,通常适用于承重构件受压区混凝土强度偏低或有严重缺陷的局部加固,主要是用来补偿或增大框架柱因混凝土强度不足而降低的承载力从而降低柱的轴压比,而本文是高强混凝土置换截面法的一个全新试验研究,即在原框架柱低周往复抗震性能实验完成后,进行抗震加固,二次实验,通过具体抗震性能参数对比,来研究这种加固方法的可行性,适用性和局限性。Replacement section method with high strength concrete is a direct reinforcement method,It is usually used to bearing structure which has lower concrete strength at compression area or serious defect,the method mainly compensate concrete strength to low bearing,at last to low the axial compression ratio of column.In this article,we do a new test research,The column which was destroyed under quasi-static cyclic test is reinforcement with this method to do the second same test,then we get specific parameters of anti-seismic performance from the test in order to research feasibility,applicability and limitations on this method.
