某礼堂大跨度弧形预应力梁设计

摘要

This paper puts forward a simplified design procedure about large-span are prestressed beams, and determines a calculation model of beam-column joint, and also makes appropriate suggestion for relaxlng the crack control requirenment through the structural selection and introduction of process designing large-span are prestressed beams on the second floor of an auditorium ( a balcony), Furthermore, the calculation method of prestressed bars is discussed systematically,which will be helpful to the design of similar engineering.%通过对某礼堂二层(楼座)结构方案选择和大跨度弧形预应力梁设计过程的介绍,提出大跨度弧形预应力梁的简化设计方法,确定梁柱节点处的计算模型,系统阐述预应力筋的计算方法,以供在类似工程中参考.
