A prefabricated energy dissipation structure system and design method with separation of gravity and lateral force

Abstract

The invention discloses a prefabricated energy-dissipating structural system with separation of gravity and lateral force and a design method thereof. The structural system includes a prefabricated shear wall and a frame column. The main beam, the main beam is installed between the adjacent frame column and the frame column, and the secondary beam is installed on the floor layer perpendicular to the prefabricated shear wall composed of the main beam, the prefabricated shear wall and the frame column. A metal damper is installed in the middle of the main girder, and supports are set under the metal damper. The design method includes determining the design scheme of the main beam, secondary beam and laminated slab composite floor, determining the design scheme of the prefabricated shear wall and frame column, the design scheme of the metal damper and support, and the design scheme of the connection node. The structural system and design method can separate the gravity and lateral force systems, facilitate the standardized design and manufacture of components, reduce engineering costs, enhance the energy dissipation capacity of the structure under earthquake action, and improve the seismic safety of the structure.

Description

technical field [0001] The invention relates to the technical field of civil structural engineering, in particular to an assembled energy-dissipating structure system and a design method that separates gravity and lateral force. Background technique [0002] Prefabricated buildings are widely used in practical engineering due to their rapid construction, energy saving and environmental protection. However, the existing prefabricated building gravity and lateral force systems are coupled together, and the internal forces of beams and columns will change with the floor, which is not convenient for the standardized design and production of components, resulting in a wide variety of prefabricated components, complex connection structures, and difficulty in reducing construction costs. cost.
