[提要]  结合《混凝土结构设计规范》( GBI10-89)的修订课题，从荷载效应的角度出发，对不平衡弯矩平行于长边时钢筋混凝土板的受冲切承载力的计算，提出了一种计算等效集中反力设计值的简化方法。该方法与美国ACI规范公式相比较，计算简便，且偏于安全。

Combined with the revision of the Code for Design of Concrete Structures ( GBJ 10-89), this paper provides a simplified method to calculate the equivalent concentrated reacting force of reinforced concrete slab-column connections with unbalance moment along an axis transverse to the long edge from the load effect viewpoint. Comparing with the design method of ACI Code, the suggested method is simplified and safety on some degree.
Keywords: reinforced concrete slabs; punching shear strength; unbalanced moment
