| Abstract: | Though the calculation results of the bending bearing capacity in rectangular steel tube concrete tests,the difference between the norms is observed and studied.By means of typical examples,the changing trends of the bending bearing capacity of the rectangular steel tube concrete under different steel ratio,different concrete strength and different steel strength are analyzed in detail,and the characteristics of different norms are obtained through the calculation of the bending bearing capacity of the rectangular steel tube concrete.The conclusion is valuable to projects and researchers. |
