摘要
介绍了1个3层1/3缩尺的钢管混凝土柱交错桁架结构水平加载试验,并应用ANSYS参数化程序设计语言APDL编制了钢管混凝土柱交错桁架结构非线性分析的命令流。有限元模拟与试验结果吻合较好,验证了有限元模型以及编制APDL命令流的正确性。应用编制的命令流,分析了柱的截面形式、桁架的刚度、高跨比、桁架的形式、荷载偏心等因素对钢管混凝土柱交错桁架结构性能的影响。
A 3 stories and 1/3 reduced scale concrete-filled tubular steel column-staggered truss structure model was tested under lateral load. A command stream of finite element analysis for the model is edited with the ANSYS Parametric Design Language APDL and the calculated results are much coincided with those of the test. Model of finite element and command stream are corret.The command stream was used to analyze the behaviors of concrete-filled tubular steel column-staggered truss structures with the different shape section of column, stiffness of truss, high-to-span ratio, type of truss and eccentric load.
