钢筋混凝土组合梁桥全过程的非线性分析

Non-linear Analysis of Complete Loading Process for Reinforced Concrete Composite T-Beam Bridge

在研究钢筋混凝土组合梁桥的过程中，采用了由简到繁的分阶段研究方法，进行了单梁构件和全桥结构的加载全过程试验，获得了钢筋混凝土组合梁桥具有两阶段受力和承载能力的全过程的认识。本文通过介绍非线性理论分析的方法，阐述了分析的结果及其应用。

A staged analysis proceeded from simple to complexis adopted in thepaper for the complete loading process tests of single composite T-beam and bridgestructure combined of composite T-beams.As the results,it is found that there aretwo developing stages of behavior and bearing capicity of the reinforced concretecomposite bridge under loading. The results of the non-linear analysis and its applications are presented finally.
