Integral Analysis About The Frame-supported Short-leg Shear Wall Structures With Inclined Column Transfer

In the actual project,when the frame-supported short-leg shear wall structures is used,it is inevitable that the short-leg shear wall is lifted by the transfer beam.So,the paper is based on the researches of Shusheng Zhong' team about this kind of structure,the finite element analysis software ABAQUS is used to do the nonlinear finite element analysis about the frame-supported short-leg shear wall structures,through which,having got that inclined column transfer is the better one to be used to this kind of structure,and also having got the influence of the seismic performance for the structures with different height of transfer beam and different angle of inclined column.In this paper,at the first,doing the vertical static analysis of a two-story,two-span,frame-supported short-frame shear wall structures with three different transfer forms,having got that the frame-supported short-leg shear wall structures with inclined column transfer is much better than the frame-supported short-leg shear wall structures with ordinary transfer beam or haunch transfer beam.Meanwhile comparing the analysis results with the results of the team got before,having verified the reliability of ABAQUS's simulation analysis.Then making the horizon low cyclic loading analysis of a two-story,two-span,frame-supported short-frame shear wall structures with five different height of transfer beam and different angle of inclined column.Through the comparence of different models' hysteretic curve,skeleton curve,stiffness degradation curve and damage of concrete,etc,having summarized and compared the mechanical behavior and failure modes of the frame-supported short-frame shear wall structures with different height of transfer beam and different angle of inclined column.At last,doing the dynamic time-history analysis of a nine-story,two-span,frame-supported short-frame shear wall structures with five different height of transfer beam and different angle of inclined column,through the analysis of different models' layer displacements,inter-story displacement angle,layer acceleration,damage of concrete and equivalent stiffness,etc,having got the influence of the seismic performance about the structures with different height of transfer beam and different angle of inclined column.Through the above analysis,the following conclusions can be drawn: when using the frame-supported short-leg shear wall structures that the short-leg shear wall is lifted by the transfer beam,recommending using the form of inclined column transfer;increasing the height of transfer beam can improve the seismic performance of the structures,but the increase is limited;after a reasonable design,the frame-supported short-leg shear wall structures with inclined column transfer show the high lateral stiffness and good seismic performance.It is recommended that the inclined column should support within the ends of the short-leg wall.
