高度比例尺

The geometric nonlinear analysis of three types of large - span annular cable truss structures is put forward by using commercial fem program . their static properties in deferent load case are concluded , and some suggestions for actual projects are also presented . base on the prime realization of its static property , parameter analysis of its static property is done consisting of deferent number of truss , deferent height of truss , deferent scale of height of masts , deferent boundary condition and deferent magnitude of pre - stress in deferent load case
本文利用通用有限元软件ansys对大跨度环形空腹索桁结构体系中三种典型的结构(即内外圈都为圆形、外圈圆形内圈椭圆形、内外圈都为椭圆形的三种外形的结构)进行了几何非线性分析，总结出各自在不同荷载工况下的静力性能，并提出一些有实际工程意义的建议。
