STAGGERED Analysis Of Shear Wall Structures

With the accelerated process of urbanization in China, a large number of high-risebuildings have emerged, which has presented new challenges to the traditionalhigh-rise reinforced concrete shear wall structures. People have been expecting shearwall structure to become the high-rise structural system with overall seismicperformance and large usage space. But traditional coupled shear wall structure cannot possess the above advantages at the same time. So to seek a new lateral forceresisting structure has become a widespread concern of the engineering world.Based on the relevant shear wall structure research results both at home and abroad,this paper proposes a new3D skip-floor staggered shear wall structure. This kind ofstructure is able to overcome the shortcomings of traditional shear wall structures(such as coupled shear wall structure), just name a few, heavy self-weight, largeshear-weight ratio, small usage space caused by shear wall spacing restrictions andinflexible layout. It has also respectively considered the impacts of shear wall layout,spatial effect and torsion effect. The author also sets up5structural models, using thefinite element software ANSYS and ABAQUS to conduct elastic-plastic staticanalysis and elastic-plastic dynamic time-procedure analysis. Based on the analysisresults, this paper compares the structural models crack developing conditions, driftangle, lateral stiffness and internal forces of the two bottom layers of structuralcomponents. In the meantime, it also analyzes the weak parts, weak components andnodes of the structure, and points out that the performance advantages of the new3Dskip-floor staggered shear wall structure compared to the traditional coupled shearwall structure. Relevant research findings of this paper can provide the technical basisand essential data for promoting the application of skip-floor staggered shear wallstructure and the preparation of the technical specifications.
