【Abstract】 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.更多还原
