Parameters of Calculating Concrete Creep by Age Adjusted Effective Modulus and Computational Analysis

在混凝土徐变计算的有效模量法的基础上,利用徐变系数和老化系数的拟合曲线数学表达式,提出了有效模量法计算混凝土徐变的计算机算法.该算法比传统的查表法有更高的精确度,而且能够快速地解决一般结构中混凝土徐变问题的计算,能方便地运用到工程实际中去.

Methods of calculating concrete creep are studied in this paper. O n the basis of age adjusted effective methods, a computational analysis method is brought forward to calculate the concrete creep by mathematics express of curve simulation of creep coefficient and aging coefficient. Compared with the traditi onal method of consulting table, it has many advantages, such as precision and q uickness. And it is more convenient in practice than the traditional method.
