Design Method of Shear Connectors for Steel Plate Concrete Composite Shear Wall

Abstract

The invention relates to a steel plate concrete compound shear wall anti-shear connector design method, and aims to solve the technical problems of compound shear wall interface shearing calculation and connector arrangement in an existing high-rise mixed structure; the technical scheme is that firstly, calculating difference between internal force distributed on a steel plate or concrete according to rigidity under an elastic state with bearing force provided with a corresponding portion under a limit state, obtaining normal section and oblique section interface shearing, and thus further obtaining interface total shearing; secondly, dividing the interface into edge zones, corner zones and a central zone according to the bearing force; furthermore, calculating a connector maximum space preventing local bending of the steel plate; finally, arranging the connector according to the interface total shearing, interface force bearing zones, anti-bending connector maximum space and internal force redistribute requirements. The method is suitable for a plane member, unifies the interface shearing and connector bearing force into the limit state, is connected with current standards, clear in theory concept, can be widely applied to the high-rise mixed structure, and thus providing excellent technical economic benefit.

Description

technical field [0001] The invention relates to a design method applied to a steel plate concrete composite shear wall connector in a high-rise composite structure, and belongs to the technical field of structural engineering. Background technique [0002] Steel plate concrete composite shear wall, as a new type of composite structural member, has been widely used in high-rise and super high-rise hybrid structures due to its high bearing capacity, good stiffness and ductility, and has been included in JGJ3-2010 "Technical Regulations for Concrete Structures of High-Rise Buildings" "middle. At present, there are two kinds of cross-section forms that are widely used: single-layer steel plate inside reinforced concrete or double-layer steel plate outside. The two parts of steel plate and reinforced concrete slab are combined through connectors and work together. This combination is reflected in the calculation of stiffness. The principle of stiffness superposition, in order to...
