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。
By introducing the design of the second floor (building block) structure and the design process of long-span curved prestressed beam, a simplified design method of long-span curved prestressed beam was proposed and the calculation model of the beam-column joint was established. Calculation of prestressing tendons for reference in similar projects.
