预应力混凝土连续梁桥的收缩徐变分析

Shrinkage and Creep Analysis of Continous Prestressed Concrete Bridge

对预应力混凝土连续梁桥收缩徐变分析的具体方法进行了探讨。文中采用按龄期调整的有效模量法结合有限单元步进法 。

Using the age adjusted effective modulus method and step by step finite element method,the whole internal force and deformation of the continuous prestressed concrete bridge at any period of time can be calculated
