摘要

摘要: 进行了8个方CFRP-钢管混凝土压弯构件的滞回性能试验。试验结果表明，纵向CFRP对方钢管混凝土有很好的增强作用，可以提高试件的承载力。对试验结果的分析表明，轴压比可以提高试件的抗弯承载力，钢管和CFRP管的变形协调一致。计算表明：试件强度均有一定退化；轴压比和纵向CFRP增强系数的增大可以提高试件的刚度，同时减缓刚度退化；轴压比在一定范围内有利于试件的抗震。

Abstract: Overall 8 pieces of specimens were experimentally investigated to study the hysteretic behaviors of the concrete filled square CFRP-steel tubular (S-CFRP-CFST) beam-column. The test results indicated that the longitudinal CFRP can provide strengthening effect for the concrete filled square steel tube (S-CFST) effectively, and the load bearing capacity of the specimen is enhanced. Based on the analysis of the experimental results, it shows that the axial compression ratio can enhance the flexural bearing strength of the specimen, also, the steel tube and the CFRP material can work concurrently both in the longitudinal and transverse directions. The computational result indicates that there are some strength degradation for all of the specimens. The axial compression ratio and the strengthening factor of longitudinal CFRP can enhance the stiffness of members, and they can also delay the stiffness degradation. However, the axial compression ratio is beneficial to aseismic behaviors within a certain range.
