中文摘要	为了探讨FRP加固火灾后钢管混凝土柱的可行性, 进行了8个钢管混凝土试件的轴压性能试验。8个试件按截面形式分为圆形和方形两组,每组包括常温下,火灾作用后未加固,加固一层及加固两层的试件各一个。加固方法采用FRP 从环向约束钢管混凝土。试验结果初步表明了FRP约束作用在提高钢管混凝土构件轴压力学性能方面的有效性。; In order to investigate the feasibility of using fiber reinforced polymer (FRP) composites for strengthening concrete-filled steel tubular (CFST) columns after exposure to fire, a total of eight CFST stub-column specimens, including four columns with circular cross-sections and four columns with square cross-sections were prepared and tested. The specimens can be classified as three categories: columns without fire exposure and no retrofitting, columns with fire exposure but without retrofitting, and columns with fire exposure and retrofitting with one or two layers of FRP. Retrofitting of columns was achieved by the external wrapping of unidirectional carbon fiber sheets with the fibers oriented in the lateral direction. The preliminary test results showed that the FRP jackets have enhanced the load bearing capacity of the composite columns effectively.; 国家杰出青年科学基金(50425823); 福建省自然科学基金项目(E0410015); 福建省引进高层次人才科研启动费
