In modern times,high-rise buildings are developing toward the direction of multi-purpose and mixed-use.So,the transferring structures are applying to them. V-shaped column,which is a new transferring structure in recent years,is also applied to the projects.In this paper,a finite analysis is applied to the V-shaped column when it is applied to frame structure and frame-core tube structure.Besides,a nonlinear finite element analysis is applied to the mechanical behaviors of reinforced concrete transferring structure with V-shaped column under the vertical load.The main work finished by author is in following:Firstly,mechanical behaviors and displacement of frame structure with transfer V-shaped column and with transfer girder at different height under lateral and vertical loads are discussed.By comparing and analyzing,the result indicates that,the mutation of inner forces of the components in the transferring layer is smaller when adopted V-shaped column;the displacement between adjacent floors in the transferring layer is smaller.Besides,the reduction of the displacement between adjacent floor is larger when adopted transfer girder.Secondly,under different lateral loads,comparison and analysis are applied to the mechanical behavior of frame structure with transfer V-shaped column and with transfer girder at different height.The result indicate that,the mutation of dominate moment of the components in the transferring layer is smaller when adopted V-shaped column.As the change of the load,the change of the moment in the beam is greater than in the column when adopted V-shaped column.Thirdly,impose the lateral seismic load to both of the frame-core tube structures with V-shaped transferring column and with transfer girder.By comparing and analyzing,the result indicates that,the mutation of the displacement between adjacent floors in the transferring layer is smaller when adopted V-shaped column.The mutation of inner force of the components in the transferring floor is larger when adopted transfer girder.Except the axial force,the mutation of inner force of the components in the transferring floor is smaller when adopted V-shaped column.Fourthly,a nonlinear finite element analysis is applied to the mechanical behaviors of reinforced concrete transferring structure with V-shaped column under vertical load. From the expansion process of the cracks and the distribution of the stress in the V-shaped column and the drag beam,we can come to the conclusion that,the drag beam bearing tension force,the column bearing pressure force,so,it is reasonable,and thickening the drag beam is better for its mechanical property.
