摘要
采用按龄期调整有效模量的时变分析有限元法 ,对城市轨道交通预应力混凝土连续刚构桥的收缩徐变变形进行了理论计算 ,并与实测结果进行了对比分析 。
Using the time dependent Finite Element Method of Age-Adjusted Effective Modulus, the author calculates the deflection which is induced by shrinkage and creep in a continuous rigid frame bridge of urban rail transit, and further compares with the site test result, the conclusion is very meaningful.
