[Abstract]:In this paper, the existing connection forms of assembled structure are summarized, including the joint connection of assembled shear wall and the connection form of assembled concrete frame beam-column joint. Compared with their characteristics and structures, their advantages and disadvantages are analyzed. For the joint connection of assembled structure, its strength composition should include concrete and steel bar connection. In this paper, the bond strength theory of new and old concrete is studied, the bond model of new and old concrete is introduced, and the research results of bond mechanism of new and old concrete by scholars at home and abroad are summarized. The shear strength of new and old concrete joints is analyzed, including shear performance and bearing capacity. This paper introduces several connection forms of assembled shear wall connection joint and assembly frame joint, including bolt connection, mechanical connection, sleeve connection, reserved hole paste anchor connection, welding connection and cow leg connection. The construction forms of these connections are analyzed, and the connection modes and applicable scope of these connection forms are introduced. The finite element software abaqus is used to simulate a compound force model of assembled shear wall with clasped hoop to restrain metal bellows connection, and the data analysis is carried out. The hysteretic properties and skeleton curves of concrete with different reinforcement ratio, axial compression ratio and concrete strength are studied, and the mechanical properties of the structure are analyzed. The finite element software abaqus is used to simulate an assembled concrete beam-column joint with tenon-flange connection. The influence of different bolt distribution on the mechanical properties of the joint is comprehensively analyzed.
