Abstract

The invention discloses a combination system of energy dissipation coupling beams and viscous dampers and a design method of the combination system, and belongs to the technical field of earthquake resistance and disaster prevention of building structures. The combination system consists of the multiple energy dissipation coupling beams and the multiple viscous dampers. The multiple energy dissipation coupling beams are arranged between adjacent two wall columns side by side. The position between the adjacent two wall columns is divided into a plurality of holes through the multiple energy dissipation coupling beams. Each hole is internally provided with at least one viscous damper. In the combination system, the energy dissipation coupling beams can provide effective stiffness and a certain damping ratio, the viscous dampers can provide high additional damping ratio and dynamic stiffness, in this way, the stiffness of a shear wall structure can be ensured, and meanwhile, seismic action can be reduced through the damping ratio, wall thickness is reduced, the cost is reduced, the building space is reduced, and good promoting prospects are achieved.

Description

technical field [0001] The invention relates to a combination system of an energy-dissipating connecting beam and a viscous damper and a design method thereof, belonging to the technical field of earthquake resistance and disaster prevention of building structures. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. At present, seismic activity is in a relatively active period, which poses a higher challenge to the earthquake resistance of buildings. [0003] Shear wall structure is a commonly used structural form of rei...
