摘要
此文研究的是用FRP加固的空心方型钢截面(用HSS表示)细长柱在轴压作用下的受力性能。用有限元分析软件Ansys建立"壳—弹簧—壳"的模型,分析参照试验共包括5根相同截面、相同长细比、沿柱纵向粘贴不同层数的FRP的HSS长柱。将分析的结果与试验结果做对比,承载力与试验值吻合较好,得出该模型的有效性。
The behaviors of axially loaded short and long cold-formed square hollow structural section（HSS）columns strengthened with fibre reinforced polymer（FRP）plates were studied.A＂shell-spring-shell＂model is established by finite element analysis software Ansys.Five long-column HSS specimens were modified.All columns have the same section,same slenderness ratio,and FRP plates were oriented in the longitudinal direction only.FEA model was effective by comparing the simulated and test results.
