Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an embedded steel truss type composite shear wall. Background Art

[0002] Concrete shear walls have the characteristics of high lateral stiffness and good durability, but they are prone to cracking and have poor ductility. For steel trusses commonly used in large-span floors, when their end support components are concrete shear walls, the current common solution is to set independent steel sections within the range of the edge components at the ends of the shear walls to connect with the steel trusses. This structural treatment will divide the steel trusses and concrete shear walls into two independent components, with poor integrity. The characteristics of steel and concrete materials are very different, and it is impossible to coordinate the force and deformation of the two components. Utility Model Content
