Quasi-Static Experimental Study On Post Cast Vertical Joint Shear Wall Of Prefabricated Building

Under the leadership of the government,the construction industry has raised the assembly building to the process of development,in response to the deterioration of the ecosystems that make up the model industry’s conversion and upgrading,and to cope with the deterioration of the growing ecosystem and to meet the demands for green development.The development of building construction is an important measure to improve the quality and quality of building construction,and it is an important measure to realize industrialization of housing,industrialization of architecture and modernization.In building construction,there are Merritt,such as construction efficiency and quality of finished goods.The assemblage force wall needs to be patchwork on the site,patchwork forms horizontal seam and longitudinal seam,and the reliable connection of seam is the key to ensuring the overall performance of the structure.In the case of the assemblage bearing wall structure,the seismic resistance of seam bearing walls is required to be tested and theoretical study to ensure the seismic resistance equivalent to that of the infill.In this paper,we propose two types of post wrapping method which can be used for both of L and convex.The main work and research results are as follows.(1)6 shear wall wall specimens with a cross-sectional ratio of 1.0 are made of six common single letter emblem.The vertical shear shear wall is made to the two L shaped brides,and the two vertical shaped beams are made of vertical shear shear walls.The static loading test of the bearing wall specimen yielded load,ductility and stiffness degeneracy,energy consumption capacity and fracture morphology.According to the experimental study,compared with the longitudinal gap shear wall and the flexural shear wall,the weight,self sufficiency ductility coefficient and capacity were reduced to 0.94%,4.49% and 4.40%,respectively,and compared with the longitudinal gap shear wall and the vertical shear wall,respectively,compared with the longitudinal shear wall and the vertical shear wall,respectively.When the axial pressure ratio was 0.3,the axial force,ductility and energy consumption were reduced to 0.86%,4.60% and 5.44%,respectively,compared with the vertical shear shear walls,and compared with the vertical shear shear walls to the vertical shear wall The decline in energy consumption and energy consumption were 11.20%,13.13%and 20.63%,respectively.The higher the axial pressure ratio,the higher the axial pressure ratio,the greater the load of the test piece,the ductility of the specimen,and the hysteresis curve.Overall,the failure of the three types of shear walls is relatively close to each other.However,the seismic performance of the L-shaped retrofitted wall is relatively close to the post wall and the seismic performance of the retrofitted vertical wall is slightly reduced.(2)The calculation model of the stiffness and load of a new type of longitudinal wall is calculated.(3)Finite element analysis of the cantilever shear bearing walls with excellent seismic performance using ANSYS finite element software was carried out.In this way,by converting parameters,under the various span ratios and various vertical seam widths,the relative performance index of the shearing force wall of the longitudinal stitches to the L-shaped empress is poured into theoretical form for the engineering application.In this paper,L-shaped post cast vertical seam shear wall and convex post cast vertical seam shear wall are proposed,and the systematic research,analysis and summary are carried out,which enriches the joint connection form of prefabricated shear wall,promotes the development of prefabricated building,and has important significance for the design and popularization of prefabricated shear wall.
