摘要

摘要: 为研究矩形截面铝合金梁的受弯性能，对剪跨比为1.5、2、2.5的9根铝合金梁进行单调加载试验，分析各试件的典型破坏形态、荷载-挠度曲线和峰值荷载，对比其极限承载力计算值和实测结果。研究表明：随着剪跨比的增加，各试件的极限承载力逐渐降低，其跨中对应挠度逐渐增加；各试件极限承载力计算值与实测结果基本吻合；随着剪跨比的增加，试件由剪切变形为主向受弯变形为主转变。

Abstract: In order to study the bending behavior of aluminum alloy beams with rectangular section, monotonic loading tests were carried out on 9 aluminum alloy beams with shear-span ratios of 1.5, 2 and 2.5 in the paper. Typical failure models, load-deflection curves and peak loads of each specimen were analyzed. The calculated ultimate bearing capacity and measured results were compared. The results showed that with the increase of shear-span ratio, the ultimate bearing capacity of each specimen decreased gradually, and the corresponding deflection of mid-span increased gradually. The calculated values of the ultimate bearing capacity of all specimens were basically consistent with the measured results. With the increase of shear-span ratio, the specimen changed from shear deformation to flexural deformation.
