计算预应力损失的关键是较准确地计算徐变应变,为此,曾提出了很多计算方法。本文作者曾从混凝土徐变的积分型物理方程出发,使用较精确的徐变定律,推导出计算预应力损失的递推公式。若有较准确的收缩和徐变实测数据或解析表达 The key to calculating the prestress loss is to calculate the creep strain more accurately. For this reason, many calculation methods have been proposed. The author of this paper used the more accurate creep law to derive the recursive formula for calculating the loss of prestress from the integral-type physical equation of concrete creep. If there is more accurate shrinkage and creep measured data or analytical expression
