摘要:
介绍了一种新型的抗侧力结构体系——钢板深梁; 利用有限元分析软件ANSYS分析了两侧加劲钢板深梁的弹塑性屈曲性能,讨论了深梁跨高比、宽厚比等参数对钢板深梁屈曲性能的影响。研究结果表明:极限承载力与钢板深梁跨高比近似成正比关系; 对厚板与薄板而言,厚板的非线性由材料的弹塑性引起,而薄板的非线性由深梁严重面外变形和材料弹塑性共同引起; 厚板对加劲肋的要求较低,可不布置中部加劲肋,而薄板对加劲肋的要求较高。
Abstract:
Steel plate deep beam(SPDB), as a new lateral resistant system, was introduced. The finite element analysis software ANSYS was adopted to analyze the elastic-plastic buckling behavior of SPDB with stiffened panel at both edges. The research work was focused on the influences of side length ratio, height-thicknessratio and so on. The result shows that the ultimate bearing capacity of SPDB is proportional to the side length ratio. The thick panel is different from the thin panel. The nonlinear behavior of the thick panel is resulted from the nonlinearity of material, but the nonlinear behavior of the thin panel is from both the nonlinearity of material and serious geometry deformation of the panel. In the design of SPDB, the interior stiffeners are necessary for the thin panel but not necessary for the thick panel.
