A cross-stiffened steel plate shear wall with side slits

Abstract

The invention discloses an intersecting reinforcement profiled steel plate shear wall with broadside slotting. The profiled steel plate shear wall comprises an embedded steel plate which is arranged in a margin plate, a lengthways end plate or a crosswise end plate is arranged between the embedded steel plate and the margin frame, a gap is arranged between a margin frame column and the lengthways end plate; the embedded steel plate adopts corrugated profiled steel plate which sets the corrugation direction as a vertical direction, and two sides of the embedded steel plate are respectively connected with two profiled steel reinforcing ribs, wherein one of the two profiled steel reinforcing ribs is arranged in a direction which forms an included angle of 45 degrees with a horizontal line, and the two profiled steel reinforcing ribs are perpendicular to each other. The embedded steel plate has large vertical stiffness; the gap between the end plate and the margin frame column can not only eliminate a probable additional bending moment generated by the embedded steel plate on the margin frame column, but can also release dimension error of the broadside of the profiled steel plate; the profiled steel reinforcing ribs which are in cross arrangement restricts the relative position of the corrugated profiled steel plate in a corrugation plane; meanwhile, the profiled steel plate shear wall can be designed into a fabricated lateral force resisting component, thus realizing a sharp improvement in field assembly degree, and reducing workload in field construction.

Description

technical field [0001] The invention relates to a high-efficiency lateral force resistance system, in particular to a steel plate shear wall. Background technique [0002] The seismic performance of a building structure mainly depends on the lateral force system of the structure, and an efficient and economical lateral force system has always been a key issue in the seismic research and design of steel structures. Since the 1970s, steel plate shear walls have received more and more research attention as an efficient lateral force resistance system. In addition to being used in the construction of new structures, they can also be used for the reinforcement of building systems that require post-earthquake repairs. [0003] Compared with traditional lateral force-resisting systems, steel plate shear walls have the following advantages: 1) large initial rigidity, good ductility, and strong energy dissipation capacity; 2) light weight, which can effectively reduce the structural ...

Problems solved by technology

After buckling of the embedded steel plate in the profiled steel plate shear wall structure, the original full shear lateral working mechanism will be changed, and the bearing capacity will decrease, which will affect the overall seismic performance of the structure
