摘要
近年来 ,大悬挑预应力斜拉索挑篷在大型体育场建筑中得到了越来越广泛的应用。本文在尝试对ANSYS软件进行二次开发的基础上 ,发展了一种适合体育场主看台斜拉索挑篷结构非线性风振响应计算分析的方法 ,同时也比较了非线性问题对这类挑篷结构风致振动的影响 。
Recently, prestressed cantilevered cable stayed canopy roof is commonly used in large stadium structures. Based on the second development of the ANSYS software, a method to calculate nonlinear wind induced vibration response which fits the stadium grandstand cable stayed canopy roof structure is developed in this paper. The effects of the canopy roof's nonlinear wind induced vibration caused by many conditions are also compared and some valuable conclusions are obtained.
