摘要
简要叙述碳纤维布加固铝合金方管简支梁的试验材料材性试验与试验方案,结合本次试验的结果分析,用碳纤维布对铝合金方管进行加固,可以提高其极限承载力,抑制梁跨中挠度的发展。通过非线性有限元理论分析,理论值与试验实测值吻合、曲线变化规律一致。
The authors briefly describe material quality testing and experiment plan of the square aluminum alloy tube simply supported beam stengthened with CFRP.This experiment shows that the ultimate bearing capacity of square aluminum alloy tube beam can be improved,and the mid-span deflection of beam can be inhibited.By non-linear theory of finite element analysis,the theoretical value and experimental value generally keep in line,so does the variation curve.
