摘要
在现有徐变计算方法的基础上，提出了适用于Ｄａｒｗｉｎ模型的徐变计算方法．给出了混凝土未开裂和开裂时的徐变计算公式．实际工程算例表明，本文提出的方法是合理的．
In the paper,based on the existing calculating method of concrete creep,a new method suitable for the Darwin model which is widely used in RCFE is presented,and some calculating formulas of creep for uncracked and cracked concrete are given.The calculated results for a practical engineering project show that the pressent method is reasonable
