按龄期调整的有效模量法计算混凝土的徐变收缩效应

The Calculation for Concrete Creep Simulation of the PC Bridge Construction Process with Age-adjuesting Effective Modulus Method

在采用悬臂施工的预应力钢筋混凝土大跨桥梁的施工控制中,要计算钢筋混凝土的收缩徐变对结构变形和内力的影响。针对这个问题,介绍了"按龄期调整的有效模量法"计算混凝土的收缩徐变效应的方法,并给出了算法。实际应用证明该法是准确的。

The creep deformation and the inner forces of PC bridges must be calculated in the simulation of the PC bridge construction process for segmental construction. This paper introduces how to use the Age adjusting Effective Modulus Method to solve this problem. We have used this method for the Xiaoxihu Bridge and the result is satisfactory.
