大跨度有粘结预应力梁的设计探讨

Discussion of Large-span bonded prestressed beams design

本文结合工程实例和笔者多年设计实践,探讨了大跨度后张有粘结预应力框架梁结构设计过程中的主要设计参数和强度验算,对张拉施工时预应力的损失进行了计算,确保了工程结构设计的经济性和合理性,并对张拉端节点处理进行了论述。

In this paper, the author works for many years of engineering examples and design practice, the main design parameters and intensity checking of large- span post- tensioned bonded prestressed frame beam design process are discussed,tension loss is calculated, to ensure that the the structural design of projects is economic and rationality ,and how to deal with tension joint is also discussed.
