Shear buckling prevention steel plate shear wall free of bearing gravity

Abstract

The invention discloses a shear buckling prevention steel plate shear wall free of bearing the gravity. The shear buckling prevention steel plate shear wall comprises a steel plate wall, steel columns and steel beams. The steel plate wall is placed in a frame formed by the steel columns and the steel beams. The shear buckling prevention steel plate shear wall further comprises horizontal stiffening ribs arranged in the horizontal direction of the steel plate wall. The horizontal stiffening ribs are arranged in the steel plate wall in a horizontal penetrating mode, and outer flanges extending in the vertical direction of the steel plate wall are arranged on the outer edges of the horizontal stiffening ribs. Spaces defined by the horizontal stiffening ribs, the outer flanges of the horizontal stiffening ribs and the steel plate wall are filled with prefabricated reinforced concrete plates. The horizontal stiffening ribs are embedded in the middle of the steel plate wall or among an upper steel plate wall body, a middle steel plate wall body and a lower steel plate wall body and welded to the steel plate wall. The steel plate wall is free of bearing the gravity load and only bears the seismic shear force or the wind shear force so that the situation that the steel plate wall is pressed too early and consequently is buckled can be prevented; and the shear buckling prevention steel plate shear wall is special for resisting shear, so that the shear resistant bearing capacity and large earthquake energy consumption performance of the steel plate wall are improved, the thickness of a steel plate is decreased, and the using amount of steel is saved.

Description

technical field [0001] The invention relates to a load-bearing-free anti-shear buckling steel plate shear wall, which belongs to the field of construction engineering and can be widely used in lateral force-resistant systems of various steel structure buildings. Background technique [0002] In the steel structure of high-rise buildings, the anti-lateral force systems used to resist horizontal forces such as wind loads and earthquakes mainly include concrete shear walls, steel supports, and steel plate shear walls. [0003] The concrete shear wall has strict requirements on the lateral movement of the structure. When used together with the steel structure, the advantage of the good lateral ductility of the steel structure cannot be brought into play. The steel support has good lateral force resistance performance, but the structure of the connection node between the support and the beam column is complicated, the amount of steel is large, the manufacturing and processing cos...

Problems solved by technology

During the construction process, the post-welding method of steel plate shear walls and steel beams is often used to ensure that they do not bear excessive vertical loads, which delays the construction period and cannot completely exempt the steel plate shear walls from bearing subsequent The dead load and live load of the structure also bear a certain vertical load and bending moment when the structure is subjected to lateral force.
