| Abstract: | According to the experimental results of pure torsional behavior of 7 box-shaped steel reinforced concrete(BSRC) beams,computation formula of crack torsion was established based on the compatibility of deformation,and computation formula of ultimate torsion corresponded with codes was established based on the equivalent reinforced method.Comparing with the experimental results,computation formulas can meet accuracy requirements and provide theoretical basis for the design of BSRC beams. |
