CFRP加固混凝土柱抗震性能的有限元分析

为验证CFRP抗震加固方法的有效性,通过介绍其抗震加固的机理,利用有限元软件ANSYS模拟轴向压力与单向及双向地震往复荷载耦合作用下其加固混凝土柱的抗震性能,并与未加固柱进行对比,论证了其对混凝土柱抗震性能提高的有效性,从而为试验及加固工程施工提供了有效的理论分析方法。

FEA of Concrete Column Reinforced with CFRP Against Seism

To prove that seismic reinforcement of the existing concrete structure with CFRP materials is one of effective methods, according to the Reinforcement mechanism of the CFRP - wrapped concrete columns, the performance of the CFRP reinforced concrete column under combined axial load and cyclic lateral load was simulated with the commercial package ANSYS. At the same time, it was contrasted with the concrete column that was not reinforced. The availability of this seismic reinforcement method was confirmed and the theory foundation was provided for experiments and projects.
