The invention relates to the technical field of building structural engineering earthquake resistance, in particular to an assembly type energy dissipation and damping device and an assembling methodthereof. The energy dissipation and damping assembly comprises an energy dissipation assembly and two connecting assemblies used for fixing the energy dissipation assembly up and down. The energy dissipation assembly comprises an energy dissipation web plate and energy dissipation stiffening ribs, wherein the energy dissipation stiffening ribs are welded on the two plate surfaces of the energy dissipation web plate, and the energy dissipation web plate is made of low-yield-point steel. Each connecting assembly is used for preventing the upper end and lower end of the energy dissipation assembly from shaking and fixing the damping device on an external structure. The device has the advantages that the energy dissipation assembly and the connecting assemblies are assembled to form the energydissipation and damping device, installation is simple and reliable, the energy dissipation web plate is made of the low-yield-point steel, and good energy dissipation and damping effects are achieved.
Description
technical field [0001] The invention relates to the technical field of anti-seismic building structure engineering, in particular to an assembled energy dissipation and shock absorbing device and an assembly method thereof. Background technique [0002] Concrete building is one of the common building forms in our country, especially prefabricated concrete building has developed rapidly. Prefabricated concrete buildings are widely used due to their high production efficiency, short construction period, and meeting the development requirements of "four sections and one environmental protection" green buildings, but their integrity and stability are poor, and their use in high-intensity earthquake areas is limited. At present, there are many energy dissipation and shock absorption technologies applied to prefabricated concrete frame structures. Studies by scholars have shown that reasonable energy dissipation and shock absorption technologies can effectively increase structural...
