This paper is a contribution to the analysis of skew cracking (orientation, spacing, maximum and residual crack width) in reinforced concrete shear walls subjected to seismic loading. First, it presents the experimental campaign of the French national research project CEOS.fr and several test results obtained by different measurement techniques applied on the test specimens. Although the tests were carried out under cyclic conditions, with or without reversing the direction, the obtained information could be compared with the results given by the application of the design codes, based on the post-treatment of stresses evaluated by a structural analysis. To that end, the reinforced concrete shear wall specimen is modelled by the Finite Element software Code_ASTER, using different constitutive models. Structural modelling is a crucial phase for a good assessment of crack width. This article proposes procedures to calculate crack width based on the fib Model Code 2010 approach with appropriate complements; this approach leads to a good agreement to the experimental results. Finally, the article presents and discusses the effects of the cyclic loading at Ultimate Limit State, as the values of residual crack width under reversing load cycles. The study of all these aspects results in operational procedures for engineering applications.

本文为分析钢筋混凝土剪力墙在地震荷载作用下的偏斜裂缝（方向，间距，最大和残余裂缝宽度）做出了贡献。首先，它介绍了法国国家研究项目CEOS.fr的实验活动，以及通过将不同的测量技术应用于试样而获得的几种测试结果。尽管测试是在循环条件下进行的，有无方向相反，但基于结构分析评估的应力后处理，可以将获得的信息与应用设计规范给出的结果进行比较。为此，钢筋混凝土剪力墙试样由有限元软件Code_ASTER建模，使用不同的本构模型。结构建模是良好评估裂缝宽度的关键阶段。本文提出了基于fib Model Code 2010方法并适当补充的计算裂缝宽度的程序。这种方法与实验结果很好地吻合。最后，本文介绍并讨论了极限极限状态下的循环载荷的影响，作为反向载荷循环下残余裂纹宽度的值。对所有这些方面的研究得出了工程应用的操作程序。
