【摘要】 采用LANCZOS方法比较系统的分析了K8型单层球壳的自振特性,在参数方案上采用了不同矢跨比、不同跨度、不同支座条件和不同屋面荷载.得出了各因数对网壳结构的自振特性的影响及其结构的自振规律.更多还原

【Abstract】 s:The dynamic characteristics of single-layer latticed spherical domes are analyzed systemtacially with LANCZOS method. In parameters, the ratio ofheight to span, span, the condition of supports and loads are concerned, we getthe influence of some parameters on dynamic characteristics of the latticed structures, and its rules are obtained.更多还原
