Abstract
Beams and slabs are main components to bear and transfer the vertical load in concrete structures and there is a great influence on the internal force analysis of the beam because of synergistic effect of beams and slabs.In this paper,the finite element analysis program SAP2000 was used for numerical analyses,and the effect of neutral axis difference between beam and slab was investigated through changing stiffness ratio of the beam and slab,where the analysis results were compared for different analysis details.The analysis results showed that results of the method which considered the neutral axis difference of the beam and slab were similar to the accurate analysis and it could be used in both force analysis and reinforcement design.关键词
