摘要

采用地震工程开源模拟软件OpenSees（Open System for Earthquake Engineering Simulation）对CFRP（Carbon Fiber Reinforced Polymer

碳纤维增强复合材料）布加固高强钢筋混凝土方柱的抗震性能进行了数值分析。采用Steel02Material和Concrete02Material材料本构模型模拟了CFRP布加固高强混凝土方柱的抗震性能;在此基础上

进一步研究了轴压比和剪跨比这2个因素对试件抗震性能的影响。将所得数值分析结果与相同条件下的试验结果对比后发现:基于Steel02 Material和Concrete02 Material材料本构

利用OpenSees

可以较好地模拟CFRP布加固高强混凝土方柱的抗震性能

并且与试验结果（滞回曲线、骨架曲线、水平承载力和位移延性系数）能够较好地吻合

从而说明该数值分析方法还可以准确地反映出轴压比和剪跨比对高强混凝土柱抗震性能的影响规律。

Abstract

To investigate the seismic behavior of high strength concrete square columns retrofitted with CFRP sheets

the nonlinear finite element analysis software OpenSees based on fiber model method was used to simulate the cyclic loading tests on retrofitted specimens.The influences of parameters

such as axial load ratio and shear span ratio

on the seismic behavior of specimens were studied.Then the simulation data were compared with the test results.The research results show that the simulation responses（hysteretic curves

envelop curves

lateral capacity and displacement ductility）of the numerical column model are in good agreement with the test data when the constitutive relationships of steel02 Material and concrete02 Material are used.Meanwhile

the influence rules of parameters including axial load ratio and shear span ratio on the seismic behavior of high strength columns were obtained accurately by the numerical method presented in this paper.
