摘　　要：设计制作了三种不同尺寸、不同约束层数的玄武岩纤维布约束混凝土方柱试件,并对其开展了抗压试验,试验测得了各试件的应力应变曲线,观测了各试件的破坏形态。试验结果表明:采用玄武岩纤维布对混凝土方柱试件进行约束,可以提高试件的极限应力和极限应变,改善试件的破坏形态。Three different dimension specimens of the square section concrete column restricted by basalt fiber sheets were designed,and the compression experiments were conducted.The stress-strain curves of the specimens were gained, and the failure pattern of the specimens were ob- served.The result of the experiment showed that the strength of the restricted specimens by the basalt fiber sheets is higher than that of the non-re- stricted ones, and the basalt fiber sheets could advance the limited deformation and improve the failure pattern.
