Prefabricated knee brace bearing energy-consuming support and construction method thereof

Abstract

The invention discloses a prefabricated knee brace bearing energy-consuming support and a construction method thereof. The prefabricated knee brace bearing energy-consuming support includes an energy-consuming supporting connecting steel assembly, energy-consuming strip steel plates and out-of-plane restraint steel plate sleeves, wherein the energy-consuming supporting connecting steel assembly includes transverse parts and vertical parts, the upper ends of the energy-consuming strip steel plates are fixed to the transverse parts, and the lower ends of the energy-consuming strip steel plates are fixed to the vertical parts; cavity spaces are arranged in the middle part of the out-of-plane restraint steel plate sleeves, the energy-consuming strip steel plates are inserted into the cavity spaces, and energy-consuming displacement gaps are pre-reserved between the out-of-plane restraint steel plate sleeves and the energy-consuming supporting connecting steel assembly. On the one hand, theprefabricated knee brace bearing energy-consuming support consumes energy, and on the other hand, the prefabricated knee brace bearing energy-consuming support prevents the falling of beams; and in the event of a failure of pre-stressed tendons in the beam, shear resistant support plates can bear the shear force transmitted by the beams and provide a second line of defense for the structure. Onesupport or a plurality of supports can be used at one beam-column joint, and the multiple supports can be operated together as a parallel system. The prefabricated knee brace bearing energy-consumingsupport is convenient to replace after an earthquake, and provides better post-earthquake recoverability.

Description

technical field [0001] The invention belongs to the technical field of shock absorption in structural engineering, in particular to a shock absorber and a construction method for dissipating vibration energy by using metal yield. Background technique [0002] With the development of the times, people pay more and more attention to earthquakes. Therefore, in recent years, the seismic design methods for structures have developed rapidly. Structures often use some mechanical devices to dissipate the energy introduced by the earthquake, so that the main load-bearing components do not suffer unacceptable damage. The damping devices currently used in structures can be mainly divided into passive control, semi-active control, active control and hybrid control. Among them, passive control technology is widely used in engineering construction due to its simple and reliable structure, stable energy consumption performance, low price, and convenient maintenance, or to improve the sei...
