预应力混凝土连续桁架梁桥设计中若干问题的探讨

Discussion on the Design of P.C. Continuous Truss Girder Bridge

本文介绍了新型的预应力混凝土连续桁架桥的特点,并就其设计中的几个问题——腹杆体系,预应力钢束及桥梁横截面的布置等进行了讨论和实例验证。

The features of a new type of prestressed concrete continuous truss girder bridge are presented in this paper. Proflems relating web-member system, prestressing tendons' profile and cross-section arrangement are discussed with numerical examples.
