A Structural Design Of Frame Supported Shear Wall With High Transfer

With the development of economy in China, the use of building space requirements, more and more tall, flexible, The lower part of the large space building layout shops, conference rooms, lobbies.Typically the upper part of wall structure, the lower part of the column-wall supporting structure. Such continuous upper wall can not be directly through landing, Need to set the conversion layer structure.Many shear wall structures supported the general location of the conversion layer1to layer2,Some in the3to5layers,or even higher.With a conversion layer frame supported shear wall structure just under the soft, Vertical stiffness of the structure changes,Conversion layer structure of upper and lower floors member forces, displacements prone to mutation,For earthquake disadvantage. Conversion layer height, upper and lower conversion layer lateral stiffness ratio is affected frame supported shear wall structure of the main factors.Based on concrete columns with steel frame supported shear wall structure engineering case study follows:1).Conversion layer in layers of different positions,example,one、three、 seven、ten.Analysis conversion layer between the upper and lower displacement angle and force changes;2).Pillar box section size change on displacement angle of impact analysis;.3).Changes in wall thickness of the floor displacement angle of impact analysis;4).Pillars of concrete columns with steel frame and ordinary concrete columns on the Structure Analysis;5).High conversion layers on the structural changes in impact indicators.This paper studies the high conversion frame supported shear wall structure under Seismic performance of the dynamic characteristics and seismic changes in the law,Draw the following conclusions:1).With the conversion layer is elevated position,Need to control the conversion layer and a layer of angular displacement ratio,Convert several layers of higher and more needs to be strengthened at the bottom of the seismic measures.2).Increased cross-sectional dimension pillar box to adjust the conversion layer of the upper and lower than the effectiveness of the displacement angle is very small,By increasing the wall just to adjust the structure of the heart,Just to make heart-shaped heart is coincident with the quality,Conversion layer can effectively reduce the displacement angle of the upper and lower ratio.3).When the conversion is greater than the adjacent layers taller than3times the upper storey,Proposed to increase conversion layer upper and lower floors of the lateral stiffness ratio.
