Based on the linear creep theory and deformation coordination principle, the calculation method and computing formulas about the inner force redistribution and the stress redistribution are investigated in this thesis, the validity of this method is demonstrated by comparison the calculated results with the tested results 基于线性徐变理论和变形协调原理,本文研究了二次预应力连续梁的徐变内力重分布和徐变应力重分布的计算理论和计算方法,并与试验结果进行比较,以求验证本文方法的可行性。
