［摘要］依据7根箱形型钢混凝土梁的受扭性能的试验结果，在变形协调基础上建立了开裂扭矩计算公式，采用等效钢筋法建立了符合我国规范计算公式形式的极限扭矩计算公式。与试验结果对比表明，建议的公式满足精度要求，可为箱形型钢混凝土梁的设计提供理论依据。

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.

Keywords:steel reinforced concrete; torsional behavior; crack torsion; ultimate torsion
