摘　　要：美国钢结构协会(AISC)给出了钢板剪力墙中梁剪力的计算公式,但未曾考虑作用在梁上的拉力带水平分量对梁产生的剪力作用。基于钢板剪力墙理想破坏模式,分析中梁所受剪力,对AISC所提出的中梁剪力计算公式进行修正,提出中梁剪力近似计算公式,并利用大型通用有限元软件ABAQUS进行验证。研究结果表明:按照修正后的方法计算中梁剪力是可行的。AISC put forward the formula of the shear force of the intermediate beam, but the formula didn＇t consider the shear force produced by the horizontal components of tension fields on the intermediate beam. Based on the failure mechanism of steel plate shear walls, this paper analyzes the shear force of the intermediate beam. The current formula of the shear force of the intermediate beam put forward by AISC is revised, which is verified by using the nonlinear finite element software ABAQUS 6.10. The results show that the method for the calculation of the shear force of the intermediate beam is feasible.
