多弹簧型钢梁柱单元若干问题的探讨
Discussions of some questions about multi-spring element
【摘要】 多弹簧空间梁柱单元可以有效地模拟空间梁柱单元在轴力和弯矩共同作用下的响应。就多弹簧梁柱单元的塑性区长度系数、内力提取截面位置、单元p-delta效应计算以及单元杆端曲率的计算进行了探讨。在讨论的基础上,通过对比计算结果与有限元分析结果以及试验结果,验证了本文论述的可靠性。
【Abstract】 Multi-spring element model is effective in simulating the combined action of axial force and moment.Length parameter of plastic region and position to get the inner force were discussed in this paper.Then the second-order effect of the element was analyzed.At last the formula about end curvature in multi-spring element was put forward.All these conclusions were certificated by comparison the calculated results and finite element analysis or experimental results.
