Simulation Study On Basic Behavior Of Building Formwork Concrete Shear Wall

Building Formwork concrete shear wall is a new type structure system.It complies with the policies on wall innovation,environmental protection and energy saving,and resolves the problem of wall innovatiom on multiple-story residential construction.The stripping operation can be eliminated during the process of construction. It uses auto dense concrete and has the performance that avoided vibrated and auto dense. It also has excellent heat-insulating property.The structure system complies with the development direction of residential industrialization and has broad development prospect in the substitution of clay brick.This paper uses the ANSYS program to do simulation study on basic behavior of Building Formwork concrete shear wall.The main research are as follows:(1) A 3D finite elment model is used to study the basic behavior of Building formwork shear wall with ANSYS program.Through comparing with the analytical results with the test results,it turns out that the model is effective.(2) The shear simulation test is done on Building Formwork concrete shear wall and general shear wall, and the effect of Zigzag loop,Stiffening rib,Expanded metal on the shear wall are analyzed.(3) The influence factors of shear strength are discussed in this paper.It reveals the influence of concrete grade, Zigzag loop ratio,longitudinal steel bar ratio, longitudinal steel bar ratio of concealed column and axial pressure ratio on the bearing capacity of Building Formwork concrete shear wall.(4) This paper discusses the basic behavior of Building Formwork concrete shear wall after changing it's mode of horizontal steel bar,including the shear wall with only horizontal steel bar, the shear wall with lateral bracing horizontal steel bar and the shear wall with assembled lacing wire.(5) Study the basic behavior on Building Formwork concrete shear wall with vertical seams.(6) Preliminary research on the basic behavior of T-shape and Z-shape short pier Building Formwork concrete shear wall is carried on in this paper.
