方钢管混凝土短柱轴压性能分析
首发时间:2007-03-28
摘要:在试验背景下,利用大型有限元结构分析软件ANSYS9.0,同时考虑材料非线性和几何非线性,通过合理的几何实体建模和正确的加载方法,模拟方钢管混凝土短柱轴心受压试验的全过程,求解出方钢管混凝土的极限承载力,总结试件混凝土强度、约束系数、钢材屈服强度对承载力提高的影响规律,与试验结果符合较好,证明了有限元分析方法的正确性和可行性。

Analysis on the Behavior of Concrete-filled Square Steel Tubular Stub Columns Under Axial Compression
Abstract:Based on the many experiments, this article, using the structure finite element analysis software ANSYS9.0, considering material non-linear and geometry non—linear question simultaneously, simulates the test of square concrete-filled steel tubular short column under the axial pressure through reasonable modeling and correct loading manner. And, deduce the limited bearing capacity of the experimental component. Furthermore, I summarize influence rule of bearing capacity\\\\\\\
