Problems solved by technology

[0003] As a widely used energy-dissipating element, steel has good energy-dissipating capacity, but its energy-dissipating capacity will be greatly reduced if out-of-plane buckling occurs. Therefore, the out-of-plane buckling problem of traditional steel dampers seriously affects its application in engineering. application in

Embodiment 1

[0025] The present invention is based on the H-shaped steel with rhombus openings, and is connected with the steel sleeve and the steel piston by high-strength bolts, and connected with the structure through the screw rod, so that when the structure is deformed, the steel sleeve and the steel piston are only in the axial direction. The relative displacement occurs, so that the built-in H-shaped steel with diamond-shaped openings avoids out-of-plane deformation and only deforms in the plane, realizing the purpose of energy consumption of the H-shaped steel with diamond-shaped openings in the bidirectional deformation structure. The structure is mainly used in bridge engineering and construction engineering seismic isolation technology with high seismic performance requirements.

Abstract

The invention discloses a diamond-shaped opening H-shaped steel damper capable of preventing out-plane buckling and relates to the technical field of disaster prevention and seismic reduction of engineering structures. The diamond-shaped opening H-shaped steel damper is composed of diamond-shaped opening H-shaped steel, an outer steel sleeve, an inner steel plate, a steel piston, screws, high-strength bolts and nuts. An upper connecting plate and a lower connecting plate of the diamond-shaped opening H-shaped steel are connected with the outer steel sleeve and the inner steel plate through the high-strength bolts correspondingly. The inner steel plate is in welded connection with the steel piston. The outer steel sleeve and the steel piston are connected with the screws correspondingly. The damper is connected with a structure through the screws and arranged in the large-deformation position of the structure. When an earthquake occurs, the two screws generates axial displacement in the axial direction, so that a web plate of the diamond-shaped opening H-shaped steel only generates buckling and shearing deformation in the plane, and the problem of out-plane buckling of a traditional diamond-shaped opening H-shaped steel damper can be effectively prevented. Therefore, earthquake energy can be dissipated stably, the earthquake reaction of the structure is reduced, and structure damage is limited.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and shock absorption of engineering structures, in particular to an H-shaped steel damper with diamond-shaped openings to prevent out-of-plane buckling. Background technique [0002] my country is located between the circum-Pacific seismic belt and the Eurasian seismic belt. Most of the country is an earthquake zone, especially the western part of my country is mostly a strong earthquake zone with frequent seismic activities. In order to minimize the losses caused by earthquake disasters, it is necessary to carry out seismic design and reinforcement of engineering structures. At present, the commonly used ductile anti-seismic design is to use the specific position of the structure as a plastic hinge, and dissipate the seismic energy through its elastic-plastic deformation, so as to meet the requirements of the anti-seismic design of the structure. The seismic control technology of str...
