Shearing type parallel mild steel quake-proof damper for building structures

Abstract

The invention provides a shearing type parallel mild steel quake-proof damper for building structures, relating to the technical field of building engineering and used for improving the quake-proof performance of the building structures, lowering the repair cost of postquake restoration and ensuring normal use of the building structures after an earthquake. The damper comprises two rectangular mild steel plates with low yield point, two lateral stiffened steel rib plates and two gusset plates, wherein the surfaces of the two mild steel plates with low yield point are parallel to each other; the four edges of the two mild steel plates with low yield point are flush; the two lateral stiffened steel rib plates are respectively welded and fixed at the left and right sides of the two mild steel plates with low yield point; the two gusset plates are respectively welded and fixed at the upper and lower sides of the two mild steel plates with low yield point; and the surfaces of the two mild steel plates with low yield point are vertical to the surfaces of the lateral stiffened steel rib plates and the surfaces of the gusset plates. The damper provided by the invention can effectively consume the seismic energy, has low cost and is simultenously convenient for repair and change.

Description

technical field [0001] The invention relates to the technology of construction engineering, in particular to the technology of a shear type parallel mild steel building structure anti-seismic damper. Background technique [0002] With the rapid development of my country's urbanization process, along with the increasingly diversified use requirements, a large number of complex high-rise and super high-rise building structures continue to emerge, which has brought new and huge challenges to seismic design-building structures can not only meet the needs of Bearing capacity calculation requirements, but also to be able to achieve performance-based design goals. In this case, according to the traditional structural arrangement, the design cross-section of beams, columns and other components must be very large, but this will lead to an increase in the structure's own weight, that is, the seismic response; in addition, there is another important contradiction that traditional struct...

In this case, according to the traditional structural layout, the design cross-section of beams, columns and other components must be very large, but this will lead to an increase in the structure's own weight, that is, the seismic response; in addition, there is an important contradiction that traditional structures experience After the earthquake shock, even if there is no overall collapse, the cost of repairing beams, columns and other components is often very high, and it will affect the normal use of the building structure
