通过对碳纤维布加固铝合金方管简支梁试验结果的分析可知,采用碳纤维布对铝合金方管梁进行加固,可以提高铝合金方管梁的极限承载力,抑制梁跨中挠度的发展。通过对梁前后两侧及梁底应变片的应变发展变化规律的研究,验证了本次试验在荷载上升阶段各测点的应变与荷载成线性关系,近似符合平截面假定。 Through the analysis of the test results of CFRP-reinforced square tube simply supported beams, we can see that using carbon fiber cloth to reinforce the square tube beam can increase the ultimate bearing capacity of the square tube beam and restrain the mid-span deflection. Through the research of the strain development and change law of the strain gauge on both sides of the beam and the beam bottom, the relationship between strain and load in each test point in this test is verified to be linear and approximately in accordance with the assumption of flat section.
