摘要:
采用比值索力迭代法模拟预应力钢结构的索力,对半刚性和柔性结构不能得到正确的计算结果。本文构建了差值补偿索力模拟方法,对半刚性和柔性构适应性好,计算稳定,较比值索力迭代法适用范围更广泛。使用有限元软件ANSYS中的参数化设计语言APDL编制了索力模拟分析程序,通过算例验证了差值索力补偿法迭代过程总是能稳定收敛到设计索力。引入的加速因子有效加快了迭代计算的收敛速度,对于本算例β取1.6~1.8时效果最佳。
Abstract:
Right results can not be obtained with tension iteration method plus the ratio of prestressed steel cable force simulation of semi-rigid and flexible structure. The paper sets up simulation of difference compensation for cable tension to get better semi-rigid and flexible structure ,adaptability and computational stability, which has a wider application over iteration method. With the parameter of software ANSYS design language, corresponding program is developed. It is found that force difference of iterative method can always converge to design cable forces and has a broader scope of use. The iteration acceleration factor β is introduced in the difference cable force compensation method, and examples show the value of β from 1.6 to 1.8 which accelerates the speed of iteration.
