摘要
采用考虑钢材损伤累积的本构模型,系统分析了结构参数对单层柱面网壳结构失效模式和失效极限荷载的影响,其中包括:不同屋面质量的影响;不同矢跨比,以及不同长宽比的影响。
Apply to thedamage accumulation model of steel, a comprehensive numerical analysis on failure models and ultimate loads of some single-layer latticed cylindrical shells is carded out with the following primary parameters： different loads distribution on the roof, various geometric and structural parameters , such as rise-to-span ratios, especially length-to-width ratios.
