单层筒形同壳结构的选型及其静动力性能分析

Structural Configulation and Static-dynamic Behaviours of Single-layed Cylinderical Latticed Vaults

本文对两端支承、两个直线边自由的圆柱形壳面的单层筒形网壳结构进行了大量的算例分析．并以结构的几何尺寸比例、网格形式、构造方案作为基本结构参数对网壳型式进行了优选．对优选出来的典型网壳结构又进行了详细的静力住能分析、自振特性分析和用反应谱法计算了地震作用．最后，对这类网壳的设计提出了建议．

This paper introduas parametrical analysis of static-dynamic behaviors for cylinderical latticed vaults supported on two ends, taking the basic geometrical proportion,the net system and the structural scheme(with the arrangement of edge beams and transverse dinphragms) as the basic variable pammeters.Based upon the analytical of a large number of individual structures with various geometrical, net system and structural arrangements, a comprehensive understanding of the behaviors of cylinderical latticed vaults is obtained,and suggestions for designers are proposed.
