摘 要: 通过63个100mm×100mm×100mm和63个150mm×150mm×150mm高强混凝土和钢纤维高强混凝土试件的劈拉试验,探讨了钢纤维高强混凝土劈拉破坏受力变形的全过程,分析了钢纤维类型、钢纤维体积分数等因素对钢纤维高强混凝土劈拉强度尺寸换算系数的影响,建议了钢纤维高强混凝土劈拉强度尺寸换算系数值. Through splitting tensile experiments on plain and SFRHSC specimens with the dimensions of 100 mm×100 mm×100 mm and 150 mm×150 mm×150 mm, the load-displacement curves for different kind of steel fibers were explored, and effects of some factors, such as steel fiber type and steel fiber volume fraction, on dimensional conversion coefficients of splitting tensile strength of SFRHSC were analyzed. The conversion coefficients of dimensional effect for the splitting tensile strength of SFRHSC are suggested.
