Abstract

The invention provides a damping ground connection type fabricated reinforced concrete tuning quality damping wall. The damping ground connection type fabricated reinforced concrete tuning quality damping wall comprises a plurality of structural beams, a plurality of structural columns, a prefabricated concrete wall, an upper connecting joint, a horizontal spring, distributed sliding support, a wall splice joint and a bottom connecting joint, the structural beams and the structural columns form a main structure, the main structure is connected with the prefabricated concrete wall separately through the upper connecting joint, the horizontal spring and the distributed sliding support, and the prefabricated concrete wall is connected with the ground through the bottom connecting joint. Whenwind damage and an earthquake comes, frequency modulation resonance occurs to the main structure and the damping ground connection type fabricated reinforced concrete tuning quality damping wall, energy of the main structure is dissipated, so that the main structure is protected, the damping effect is good, inter-story displacement distribution is more uniform, the structural damage mode is improved, the corrosion resistance and the fire-resistant performance are good, the construction is simple, and the assembly degree is high.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structural systems of civil engineering, in particular to a damping grounding type assembled reinforced concrete tuning mass damping wall. Background technique [0002] Earthquakes are one of the most destructive disasters, and the strong earthquakes that have occurred in recent years have caused huge loss of life and property. my country is one of the regions with frequent earthquake disasters in the world. In 2017 alone, there were 19 earthquakes of magnitude 5 or above in my country. How to actively improve the earthquake resistance and disaster prevention capabilities of engineering structures is of great significance to safeguard the safety of people's lives and property, and stabilize social and economic development. With the continuous development of the theory and technology of disaster prevention and shock absorption of engineering structures, the design concept has gradually develo...
