摘要
从预应力张拉整体结构出发,对传统的四角锥网架的刚性弦杆进行柔性预应力改造,探讨了基于蒙特卡罗(Monte Carlo)有限元法下的结构的"基于性能"的可靠性设计法,并在ANSYS程序上对该张拉结构进行静力计算和适用性分析。
Starting from prestressed tensegrity structure, flexible prestressed innovation to rigid chord of tradition- al square pyramid space grid was conducted and probability design method based on the ＂performance -based＂ of structure under Monte Carlo finite element method was discussed, and static force calculation and applicability analysis on this tension structure were carried out on ANSYS.
