某工程中大跨度混凝土悬挑桁架的设计

The Design of Long-span Concrete Cantilever Trussin Project

结合具体工程,介绍了大跨度混凝土悬挑桁架选型时考虑的主要因素、计算分析时计算参数的设定及工程设计过程中应考虑的主要问题。还对比分析了不同桁架形式及杆件边界条件对桁架内力的影响。

Based on the application in a certain project, the critical factors to consider to select suitable concrete cantilever truss system, the important calculation parameters and the main issues to be considered during design process are introduced in this paper.Besides, the effect of different truss systems and different beam boundary condition to forces distribution in truss are also discussed.
