摘要:
应用薄壁圆筒的双剪统一强度理论极限解,考虑材料中间主应力的影响和内圆钢管的薄壁效应,提出了FRP-混凝土-钢双壁空心管短柱轴压承载力计算公式.借助非线性有限元分析软件ANSYS,建立了组合柱在轴心压力作用下的非线性有限元计算模型,得到了各构件极限承载力及应力-应变关系全过程曲线,并将有限元结果与理论公式计算结果、文献试验结果进行对比验证,吻合较好;在此基础上讨论了荷载对构件纵向应力分布的影响以及钢管厚径比、混凝土强度等对构件承载力的影响规律.
Abstract:
Using the twin shear unified limit solutions of thin-walled cylinder, the formula of axial bearing capacity for FRP-concrete-steel double-skin tubular short columns was presented by considering the influence of intermediate principal stress and the internal thin-walled steel tube effect. Nonlinear element analysis models of composite columns under axial load were developed by using ANSYS program. Then, the ultimate bearing capacities and the stress-strain relationship curves for members were carried out. The finite element results agree well with the calculated results obtained in the paper and test results from the references. Based on the results achieved influences of loads on the stress distribution and the thickness to diameter ratio for steel tube and the concrete strength on bearing capacities for members were studied
