Structural Analysis Of Frame-core Wall Structure With The Horizontal Strengthened Story

It is well known that impact on level load increases accordingly, and sidewisedisplacement improves quickly, with the height updating of high-story buildingHence，control of sidewise distortion of high-story building under the role of seismicload and wind load turns into a significant subject of research on high-storybuilding．In recent years，some scholars have put forward that the strengthened storystructure should be used in reinforcing the collaborative role between tube structureand the columns in the ambient story to command sidewise shape, accordingly to putlevel bracket with rigid number between the tube and the columns. or setcircumambient region with rigid quality along the lesser frame, which is the mostsimply used structural form of frame-tube wall form with level strengthened story．It isan effective step to stop the form level-moving oppose the influence of the wind bysetting the level strengthened story．When the effect of earthquake occur．It will leadto an unexpected change in the stiffness and internal force of the structure,and lead tocompose a lepto layer, which will cause it tricky for the inside mechanism of thestructure to implement its expansion bending system．In this paper, the large-scale finite element software ANSYS, which is resettled toestablish the finite element analysis model according on the basis of the setting schemeof the frame-tube structure with various level strengthened story．Then, we adoptedthe time-history analysis method to analyze the level seismic power for variousstructures，and a summarize and compare seismic response of displacement period,response inherent force of structure with different level enhanced story, summarizemechanics of reduction of level displacement and improvement of level resistant andrigidity of structure on the basis of the level seismic analysis，and also provide somesuggestions for the seismic design for the same structure for reference．...
