摘要
结合某运动中心的大跨度预应力混凝土框架梁设计实例,简要介绍了预应力框架梁的预应力损失、次弯矩计算、抗震设计要点以及主要构造措施,为预应力框架设计提供了一定指导。
Combining with the design example of the large-span prestressed frame beam of some sports center, the paper introduces the prestressed loss briefly, the calculation of the secondary bending moments, the anti-seismic design points and the main structure measures, so as to provide certain direction for the design of the prestressed frame.
