摘　　要：进行15组玄武岩纤维(BFRP)布约束素混凝土短柱的轴压试验。试验结果表明,同等约束条件下,随着截面高宽比的增大,BFRP布约束混凝土柱强度与未约束柱强度的比值逐渐减小,截面为方形时约束效果最强,当截面高宽比为2.0时,BFRP布的约束效果很弱,BFRP布约束混凝土方形与矩形截面柱的强度存在一定的尺寸效应。15 groups of axial compression tests were conducted on BFRP sheets confining plain concrete short columns. The test results also indicate that under the same constraint condition, with the section height-width ratio increases, the strength of BFRP sheets confining concrete columns to the strength of the columns without confinement ratio diminishes. The confinement effect is strongest when the section is square, the confinement effect of BFRP sheets is very weak when the section height-width ratio is 2.0. The strength of BFRP sheets confining square and rectangular columns had certain scale effect to some extent.
