Study On Mechanical Properties Of Diagonally Reinforced Hollow Shear Wall

As the development of new urbanization，the large-scale development ofhigh-rise buildings has become an inevitable trend．Reinforced concrete shear wallstructures account for a large proportion of high-rise building structures in ourcountry．The principle stress distributions along the diagonal direction as the responseof seismic force．The distributed reinforcement can’t resist principle stress directly，so it’s easy to crack in shear wall．What’s more, the weight of RC shear wall is solarge， so the distributed reinforcement is dense， it’s not convenient forconstruction．Diagonally reinforced hollow shear wall structure is designed for theseproblems．It can improve the mechanical properties of traditional shear walls．In thispaper，the mechanical properties of diagonal reinforced hollow shear wall structurehas been done a detailed analysis，the main contents are as follows：By summarizing the study methods of reinforced concrete shear wall，creatingfinite element models rely on test components and comparing the conclusion tosummarize laws of modeling，it can also be used to verify the ability of modeling.Combining the patent of diagonal reinforced hollow shear wall structure and relatedcode for design of structures，basic parameters of diagonal reinforced hollow shearwall and ordinary shear wall can be set．Creating diagonal reinforced shear wallmodels and compare the differences of capacity and ductility with ordinary shearwall．Setting up holes in diagonally reinforced shear wall structure and analyzing byANSYS software．The maximum improvement of its carrying capacity reaches29.4%，corresponding improvement in ductility reaches53.3%．Comparing thedifferences of capacity and ductility after setting up holes in diagonally reinforcedshear wall to draw a judgment of the force or deformation laws for diagonallyreinforced shear wall．Comparing the differences of capacity and ductility betweendiagonal reinforced hollow shear walls and traditional shear walls，the maximumimprovement of its carrying capacity reaches14.4%，corresponding improvement inductility reaches21.4%．The reduced weight is different for walls of different aspectratio after setting holes．By comparing cost changes for increment of steel bars andreduction of concrete，we can draw the conclusion that if the diagonal reinforcedshear wall can be right designed，the carrying capacity and ductility can be improved，the project cost can also be saved． On the basis of summarizing finite element analysis conclusion of diagonallyreinforced shear wall and its patent，putting forward the best principles for diagonaland distributed reinforcement；giving advices for setting holes in shear walls withdifferent aspect ratio and completing the best location maps for settingholes．Introducing the principle of selecting filler material and summarizing the scopeof application for diagonally reinforced shear wall according to its patent；Providingconsultation for construction process in practical application rely on characteristics ofdiagonally reinforced shear wall．...
