摘要
文献[1]提出了中值系数法,将混凝土徐变积分方程式简化为代数方程式。本文通过对混凝土的松弛问题,用数值方法解积分方程求得中值系数值。然后,按同样方法求得钢筋混凝土轴压构件内力重分布问题的中值系数值。比较结果表明,两者非常一致。因此可作为一般混凝土徐变问题的中值系数值。
Mean value factor method was presented in reference (1) to simplify an integral equation of concrete creep into a simply algebraic equation. In this paper, the mean value factor was obtained by using numerical method to solve the integral equation for the relaxation problem of concrete. The results, in comparison with those obtained from the internal force redistribution problem of reinforced concrete members under axial loading, showed very good agreement. Therefore, these values can be used for general creep problems of concrete.
