摘要
以高强钢绞线网加固RC柱低周反复荷载作用下的试验研究为基础,采用ANSYS有限元软件,建立了加固柱的有限元计算模型,进一步分析加固柱的抗震性能,得到加固柱的滞回曲线、骨架曲线、应力应变曲线等,并将数值计算与试验结果进行了对比分析。结果表明:数值分析得到的加固柱滞回曲线、骨架曲线与试验结果吻合较好,数值计算可为试验研究提供有益补充。
Based on the low reversed cyclic loading experimental research of RC column reinforced by high strength steel wire mesh,the finite element computing model of reinforced column is established by the finite element software ANSYS,the seismic behaviors of the strengthed columns further are analyzed,the hysteresis curves,skeleton curves,stress strain curve of strengthed columns are obtained,and the numerical calculation and test results are compared.The results show that the numerical analysis of reinforced column hysteresis curves,skeleton curves agree well with the experimental results,and the numerical simulation can provide useful complement to experimental study.
