现浇混凝土悬挑桁架在舞台项目中的应用

On application of cast-in-place concrete cantilever frame in stage programs

以山西大学商务学院学术交流中心报告厅项目为例,该项目设计时结合二层看台布置,采用现浇混凝土悬挑桁架结构形式,对现浇混凝土悬挑桁架进行了详细的计算。实践证明:对于舞台之类大悬挑结构,现浇混凝土桁架结构形式是一种轻巧、受力合理的结构形式。

Taking the lecture hall project of academic exchange center of Shanxi University Business Affairs Academy as the example.The paper adopts the cast-in-place concrete cantilever frame by combining with the audience allocation on the second floor,calculates the cast-in-place concrete cantilever frame,and proves by the practice that the cast-in-place concrete cantilever frame is a light structure form with reasonable stress for the large cantilever frame of stages.
