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。 So far, the stress loss of prestressed reinforced concrete beams has been calculated according to the nonlinear elastic creep theory. Because of the complex calculation, there is no accurate solution. In this article, the author proposes a new solution that can be used to obtain the exact value of the stress loss calculation. And given a practical example, with such a rigorous method, we can compare other values ​​obtained by the approximate method with the theoretical values ​​to observe the reliability of the approximation method.
