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。
High-strength concrete replacement section method is a kind of direct reinforcement method, which is usually applied to the local reinforcement of concrete with low strength or serious defects in the compression zone of the load-bearing component, mainly to compensate or increase the decrease of the strength of the frame column due to the insufficient strength of the concrete , This paper is a new experimental study of high-strength concrete replacement section method, that is, after the low-cycle reciprocating seismic performance experiment of the original frame column is finished, seismic strengthening and secondary experiments are carried out, and the specific seismic performance Parameter comparison, to study the feasibility of this reinforcement method, applicability and limitations.
