Energy consumption damper based on tension compression and yield of trepanning steel plate

Abstract

Theinvention relates to an energy consumption damper based on the tension compression and yield of a trepanning steel plate, and belongs to the field of buildings. The energy consumption damper basedon the tension compression and yield of the trepanning steel plate comprises a trepanningcore plate, external constraint plates and cone-shaped connecting pieces; a first connecting hole and a secondconnecting hole which are used for connecting the cone-shaped connecting pieces are formed in the trepanning core plate, and a third connecting hole used for connecting the externalconstrain plates isformed in the trepanning core plate; the cone-shaped connecting pieces are located at the upper and lower ends of the trepanning core plate, and the inner ends of the cone-shaped connecting piece canslide relatively on the trepanning core plate through a second fastener located in the secondconnecting hole under the action of external force; and the external constrain plates arelocated on the twosides of the middle of the trepanning core plate, and are connected with the trepanning core plate through a third fastener located in the third connecting hole. The invention provides a novel energyconsumption device for structure seismic of props, piers and the like.

Description

technical field [0001] The invention relates to the field of construction, in particular to an energy dissipation damper based on the tension-compression yield of perforated steel plates. Background technique [0002] At present, earthquakes are in a trend of high frequency occurrence. The huge damage caused by the earthquake not only has an impact on the national economy, but also endangers personal safety. How to build new high-performance earthquake-resistant buildings has become the focus of civil engineering research at this stage. At present, ductile design and shock-isolation design are mostly used in seismic design. Ductility design usually uses plastic hinges to dissipate energy, but this will undoubtedly cause damage to the structure that is difficult to repair. The energy-consuming device consumes seismic energy, and has good repairability characteristics after the earthquake. Most scholars have conducted research on energy-dissipating devices and applied them i...
