摘要
针对斜坡上金属脚手架构造计算模型,对各种脚手架模型分别在两种边界情况下用有限元方法进行稳定性对比分析,得到各种结构的失稳模式、荷载-位移全过程曲线,将每种结构算出初始缺陷对极限承载力的影响。可根据计算结果,对斜坡上脚手架的边界条件、初始缺陷等采取措施。
Calculation model is built up for metal scaffold on slope; and by means of FEM, stability analysis is made on scaffold models of various kinds respectively under two boundary conditions to obtain the stability failure patterns and load-displacement curves of different structures and calculate out the influence of initial defects on the limit load capacity of each structure. Measures may be taken against the boundary conditions and initial defects of scaffold on slope in accordance with the calculation results.
