Research On Seismic Performance Of Short-limb Shear Wall Structure

Due to its flexible layout,short-leg shear wall structure can meet people's actual demand for further improvement of living conditions.At present,short-leg shear wall structure has been widely used in high-rise residential projects.However,the seismic performance of short shear wall structure still has some research significance.On the other hand,there are many research methods about the seismic performance of structures at the present stage,so it is bound to have some limitations to use only one method to study and analyze the seismic performance of structures.Based on this,this paper takes hefei ligaojun royal family project as an example to study and analyze the seismic performance of short-leg shear wall structure,and makes a comparative analysis of the calculation results of different methods.At the same time,the seismic performance of the short-leg shear wall structure is comprehensively evaluated based on the calculation results of the energy method.The main work of this paper includes the following aspects:The first part is related theoretical basis part.The background,significance and definition of short-leg shear wall are introduced respectively,and the basic principles of nonlinear analysis method and energy analysis method are emphatically introduced,which lays a necessary theoretical foundation for the research of this paper.In the second part,ABAQUS software is used to simulate and analyze the influence of various factors on the seismic performance of short shear wall.Different models are built according to different conditions,different constraints are added,vertical uniform load and horizontal reciprocating displacement load are applied,then the grid is divided and solved,and finally the seismic performance is compared.The third part is the calculation and analysis part.First of all,Midas software was used to construct the calculation model,and different analysis methods were used to calculate the deformation and energy of the model under the action of frequent earthquakes and rare earthquakes.At last,based on the analysis results,the seismic performance of short-leg shear wall is reviewed,and it is considered that the seismic performance of short-leg shear wall structure can meet the use requirements.
