Tensile stress-strain relationship of engineered cementitious composites reinforced by high-strength stainless steel wire mesh

  • 摘要: 为了研究高强不锈钢绞线网增强工程水泥基复合材料(Engineered cementitious composites,EEC)的受拉性能,考虑高强不锈钢绞线配筋率、ECC抗拉强度、高强不锈钢绞线网增强ECC试件宽度3个影响因素,对设计的27个高强不锈钢绞线网增强ECC试件进行了单轴拉伸试验。试验结果表明,高强不锈钢绞线网增强ECC受拉试件的开裂应力和极限应力随着钢绞线配筋率、ECC抗拉强度的增大而增大;增大试件宽度对试件的开裂应力和极限应力几乎无影响。基于试验结果,提出并建立了高强不锈钢绞线网增强ECC受拉本构模型,推导了开裂应力和极限应力计算公式。经验证,计算结果与试验结果吻合良好,说明所建立的受拉本构模型可准确描述高强不锈钢绞线网增强ECC的受拉应力-应变关系。
