摘要/Abstract

摘要： 本文在评述德尔夫特技术大学提出的计算方法的同时,考虑到部分预应力混凝土在大多数情况下控制的裂缝宽为δ_fmax≤0.1mm,因而提出了当δ_fmax≤0.1mm时考虑受拉区混凝土工作的裂缝宽计算法。借助德尔夫特技术大学实验报告的数据,用两种方法进行实例计算和比较,最后表明当δ_fmax≤0.1mm时考虑受拉区混凝土工作的计算方法是合理的,也是简便可行的。

Abstract: On the basis of the controlled crack widths (δ_fmax≤0.1mm in most cases) of partially prestressed concrete beams, this article mainly tackles the computing method of crack widths with respect to the work on concrete intensile regions when δ_fmax≤0.1mm. The computing method put forward by Delft University of Technology,The Netherlands, is evaluated.With the help of the status in the test report of Delft University of Technology and by sample computation as well as a comparison between the two methods, this computing method is finally verified to be reasonable, simple, convenient and adoptable.
