The invention relates to the technical field of anti-seismic, and proposes an energy-consuming swing substructure and a method for strengthening existing buildings, including A. Set up reinforcement structures around the original building, first fix the foundation on the ground around the original building; B. The bottom surface of the rocker is hinged on the foundation, and the two sides of the bottom are connected to the foundation through dampers; C. The connection between the rocking part and the original building, the rocking part is connected to the existing building through the energy-consuming truss, and the energy-consuming truss and the rocking part form a triangular structure. The original building uses the energy-consuming truss to drive the rocker to dissipate energy through the damper; when the earthquake intensity is high, the energy-consuming truss and the damper are used between the original building and the rocker to dissipate energy, and the limit device limits the swing of the rocker. Through the above technical solution, the problem of difficult maintenance and replacement of existing building reinforcement structures in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of earthquake resistance, in particular to an energy-consuming swing substructure and a method for reinforcing an existing building. Background technique [0002] From the global major earthquake disaster survey, it can be found that more than 95% of the casualties are caused by damage or collapse of buildings. Improving the seismic performance of buildings is one of the main measures to improve the comprehensive defense capability of a city, and it is also a major task of "resistance" in the work of earthquake prevention and disaster reduction. At present, the seismic design on the market is generally to add seismic design during the construction of the building to increase the seismic performance of the building, but some buildings are not designed with seismic design, and the reinforcement structure is added after the main body is completed. These reinforcement structures generally need to destroy the mai...
