摘　　要：由于使用功能的要求,越来越多的民用建筑出现大跨度梁的情况;而预应力梁具有减小截面尺寸、提高抗弯承载力、减小挠度及提高抗裂能力等优点,也得到了广泛的应用。本论文通过具体的实例介绍大跨度预应力梁的计算分析过程及设计要点,对设计人员有一定的参考意义。Due to the requirements of using functions,more civil buildings have large-span beams;and prestressed beams have the advantages of reducing section size,improving flexural bearing capacity,reducing deflection and improving crack resistance,which have been widely applied.This paper introduces the calculation and analysis process and design points of large-span prestressed beams through specific examples,which has certain reference significance for designers.
