本文提出了一个模糊的，固定的裂纹方法的背景下，增强工程水泥基复合材料（R/ECC）的分析建模的验证。通过对六个承受纯剪切的R/ECC板的分析进行了验证。结果表明，所提出的模型是能够复制的面板的各种响应，以及，提供的ECC的拉伸性能进行校准，从面板测试获得的。这些响应包括载荷-变形响应、主应力和主应变的大小和方向以及破坏模式。结果还表明，在ECC中的平均裂纹剪切传递与显式涂抹模型表示的可能性。最后，本文包括预测的抗剪承载力的R/ECC面板的配筋率范围很广，并得出结论与讨论有关的因素影响的抗剪强度。
This paper presents the verification of analytical modeling for reinforced Engineered Cementitious Composite (R/ECC) in the context of a smeared, fixed crack approach. Verification is provided through the analysis of six R/ECC panels subjected to pure shear. The results demonstrate that the proposed models are capable of replicating various responses of the panels well, provided that tensile property of the ECC is calibrated against those obtained from the panel tests. These responses include load-deformation responses, the magnitudes and directions of principal stress and principal strain, and failure modes. The results also demonstrate the possibility of representing the average crack-shear transfer in the ECC with an explicit smeared model. Finally, this paper includes predictions of the shear capacity of R/ECC panels with a wide range of reinforcement ratios and concludes with discussions regarding factors influencing shear strength.
