Under long-term loads,concrete creep deformation was not only connected with current stress,but also depended much on the stress history. Generally,every step of creep calculation methods needs to memorize the whole stress history,causing very poor computing efficiency.
混凝土在长期荷载作用下的徐变变形与应力作用历史密切相关,常见的徐变计算方法需记录每一步应力变化,占用大量的存储和计算空间,效率低;采用指数形式徐变度函数可利用指数特点建立只记录当前应力的增量递推式,但不适于应用更广泛的非指数函数形式徐变预测模型。
