为了分析预应力混凝土斜拉桥与时间相关的混凝土徐变和收缩效应及预应力筋的松弛效应,本文提出了一种计算机分析方法。该法也可处理由于几何形状的改变和轴力引起弯曲所造成的刚度变化的非线性特性。
In order to analyze the time-dependent concrete creep and shrinkage effects and the slackening effect of prestressed tendons in prestressed concrete cable-stayed bridges, a computer analysis method is proposed in this paper. The method can also deal with non-linearities in stiffness due to changes in geometry and axial forces caused by bending.
