摘要
采用结构通用有限元软件SAP 2000,对榆林商会张弦桁架采光顶进行了零荷载状态、初始状态和荷载状态的全过程分析,采用"荷载预组合"的方法,实现非线性工况的组合,可为同类张弦结构的分析和施工提供参考。
The Yulin Chamber of Commerce Building truss string structure roof was analyzed by means of SAP2000,which included zero loading state,initial state and loading state of whole procedure of construction.The problem of combination of nonlinear caseload was solved by use of pre-combination.This discussion was carried out to provide theoretical references for the design and construction of similar structures.
