摘要:
提出基于合理预应力取值的二级优化方法对预应力斜拉网格结构进行静力优化,对预应力优化和截面优化分别采用不同的目标和方法.杆件截面尺寸的二级优化采用结构自重为目标函数,优化方法可以采用拟满应力法; 对预应力取值的一级优化可以采用结构应变能为目标函数.用ANSYS可编程语言APDL编制采用初始应变影响矩阵法和多次复形法进行预应力取值优化分析的程序,并对按不同目标函数进行预应力取值优化得到的结果进行了比较.采用不同目标函数得到的预应力取值优化结果有所差别,宜根据实际需要选择合适可行的目标函数.
Abstract:
A two-stage optimizing method was put forward, which was based on the optimum of proper prestress of stay cables. Different objects and methods were applied to prestress optimization and section optimization. Self-weight of structure was the object function in the two-stage optimizing method for frame member sections, and the optimization method was imitative full-stress design method. Stain energy of structure was the object function in the one-stage optimizing for prestress definition. Programs according to the initial-strain-contribution-matrix method and multi-complex method obtained by ANSYS parametric design language APDL were worked out for the prestress optimization; results of different objective functions were compared. Different methods lead to different prestress optimization results, so it is necessary to select appropriate object functions.
