摘要
本文通过45m×81m双层柱面网壳工程实例,在多种方案下的计算分析,对柱面网壳结构造型、计算假定和结构分析方法等作了较全面的概括;对于温度应力影响、支座水平推力处理等不可回避的问题也作了较详细的论述;指出网壳支座节点与平板网架支座的不同点,并通过实际工程支座的设计,提供了网壳支座的设计思路和方法.
Based on the design and research of 45 m 81m double-layer barrel vault,this paper gives the structur- al style selection,the method of analysis and calculation.This paper also analyse static force characteristic of thebarrel vault under different kinds of plans.Finally,the effect of temperature stress and horizontal support reac- tion will be under discussion.
