体外预应力混凝土桥梁非线性分析

建立了可以对体外预应力结构进行全过程分析的计算模型，该模型考虑了影响结构力学性能的各种主要变化因素，并着重分析了节段施工，节间有接缝的体外预应力结构，计算与实验结果较为吻合，同时指出了接缝处的刚性转动是影响节段施工体外预应力结构力学性能的关键因素。

Nonlinear Analysis of Externally Prestressed Concrete Bridges

A numerical model which can analyze the full - range behavior of externally prestressed concrete structures is presented in this paper. This model takes into account major factors having influences on the structural behavior. Emphasis is put on the analysis of segmental construction with joints and the analytical results are quite coincident with test results. The paper points out that the rigid rotation at the joints is the key factor on its structural behavior.
