予应力混凝土梁按非线性弹性徐变理论应力损失的一个新解法

An Exact Calculation of Stress-loss in a Pre stressed Concrete Beam according to the nonlinear Elastic-creeping Theory

  • 摘要: 到目前为止,予应力钢筋混凝土梁的应力损失按非线性弹性徐变理论来计算,由于计算复杂,尚无任何精确的解法。在本文中,著者建议了一个新的解法,可以用来求得予应力损失的计算精确值。并且举了一个实际的算例,有了这样严格的方法,我们可以将其它用近似方法求得的值来和理论的数值相比较,用以观察近似方法可靠的程度。

     

    Abstract: Till now, for the problems fo find the stress—loss of a prestressed concrete beam according to the nonlinear elastic-creeping theory, there exist not any exact solving methods. In this paper, the author suggestes a method, with which we may find out the exact value of stress-loss, and a practical example is worked. By comparing this method and the approximate method stated by the author, we may observe the reliable degree of the approximate method.
