摘　　要：框架结构梁端楼板设缝可以减少现浇板对梁端刚度和承载力的影响,因此该方法有利于实现"强柱弱梁"机制。本文在研究梁端楼板设缝后梁柱的合理线刚度比基础上,通过构造设计,并建立有限元模型进行模拟分析,据此提出RC框架结构梁端楼板设缝的合理建议。Slot in beam-end-slab can eliminate the reinforcement on rigidity and bearing capacityof beam ends, thus, the mechanism of ‘strong-column-weak-beam＇can be achieved by this method. in this paper,the rational linear stiffness ratio of beam with slot in beam-end-slab to column and the construction measure of slot are discussed,and the finite element models are established and analyzed. On the base of these,the advices for design method of RC frame structure with slot in beam-end-slab are suggested.
