This paper analyzed the results of the interface shear strength tests of 47 concrete-filled square steel tube and 18 concrete-filled rectangular steel tube specimens at home and broad． A formulas was proposed for calculating the standard value of interface shear strength． The important role of diaphragms in raising the co-operation of steel tube and concrete was verified by a test in Japan，i． e． the diaphragms could prevent the relative slip between the steel tube and the concrete in it．
