Seismic Performance Analysis Of Prefabricated Hollow Shear Wall System

Prefabricated Building System is a concept contains “green”,can reduce the overall Self-respect of the structure in reality,and has good insulation and heat insulation performance,short construction period,low construction cost many advantages,thus becoming the national "green house" concept Development direction.After entering the "Thirteen Five" plan,the state frequently introduce policies to encourage the construction of prefabricated system sound and rapid development。In order to further improve the assembly building to further enhance the comfort level of the building,paper-based research scholar made before,for prefabricated structural shear wall structure improved by adding holes inside a solid shear wall In this way,a fabricated hollow shear wall structure system is constructed,which is referred to as the hollow shear wall system hereinafter.The fabricated hollow shear wall system is realized by embedding hole internal formwork in solid shear wall components to form hollow holes.At this stage is more limited study of the seismic performance of this system,which Based on the ABAQUS finite element software tools,the performance of hollow shear wall system carried out a detailed analysis of the work performed mainly as follows:1,Selected steel and concrete shear wall structure material corresponds constitutive model,combined with existing literature solid member shear test.Then the next step,structural model of existing experiments in comparison data,and on this basis,to establish the same structure model parameters.At last,compute this model file and get the sequel,such steps will stand in the rationality of consider modus.2,Hollow holes are established 5.2%,10.4%,15.6%,and a hollow solid model shear shear model,and were subjected to pretended earthquake loading in the load-displacement curve,assume aptness and a aptness of the out of shape.Then the next step,juxtapose these parameters and verify the feasibility of the hollow shear wall scheme.For four shear failure mode analyzed,combined with changes in the mechanical properties of the shear,a reasonable selection of porosity of the hollow.The results showed that the hole was 5.2 percent of hollow shear wall,compared to solid wall,the resist earthquakes function of the structure to accord the postulate,and possess superior ductility function.3,On the basis of selecting the appropriate porosity of the hollow shear wall and analyzing the failure morphology,the ABAQUS finite element tool is further used.Were studied,concrete strength,vertical bar diameter distribution,the distribution of the horizontal Reinforced interval,broadness of column longitudinal buttress edges dark,dark column stirrups and form holes that form seven specification for hollow structural concrete shear wall of axile compression proportions influences.Derived from these seven constants,the load of the hollow member shear-displacement bend line of rigidity humiliation,ductility function,energy dissipation detailed comparative analysis,the parameters satisfy reasonable requirements under opposition earthquake formulate.
