摘要：
In order to study the tensile performance of the engineered cementitious composites (EEC) reinforced by high high-strength stainless steel wire mesh, the parameters of reinforcement ratio of high-strength stainless steel stranded wire, tensile strength of ECC and width of ECC reinforced by high high-strength stainless steel wire mesh specimen were considered, and the uniaxial tensile tests of total of 27 test pieces were carried out. The test results show that the cracking stress and ultimate stress of the specimens increase with the increase of the steel strand reinforcement ratio and ECC tensile strength. The crack stress and ultimate stress of the specimens are almost not affected by increasing the width of the specimen. Based on the test results, the tensile constitutive model of high-strength stainless steel stranded wire mesh reinforced ECC and the formulas for calculating the cracking stress and ultimate stress were proposed. It is proved that the calculated results are in good agreement with the experimental results, which indicates that the established tensile constitutive model can accurately describe the tensile stress-strain relationship of ECC reinforced by high-strength stainless steel wire mesh.
