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

• 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 ,可以很方便地计算出预应力混凝土连续梁桥从施工到成桥以及成桥后任意时刻任意截面的内力与变形
