Problems solved by technology

Under the action of a large earthquake, when the core stressed steel enters the plastic working state after yielding, compared with the elastic working stage, the effect of increasing the structural stiffness is not obvious, which limits the further development of energy dissipation capacity

Abstract

The invention discloses an earthquake-proof wall and a construction method thereof. According to the earthquake-proof wall, a rigidity enhancement structure is arranged between each end of anti-bending supports and a corner adjacent to the end on a square framework, wherein each rigidity enhancement structure comprises a first spring, a second spring, a first rigidity regulation plate which is fixed on a column of the corresponding corner and used for limiting the displacement of the first spring and a second rigidity regulation plate which is fixed on a beam of the corresponding corner and used for limiting the displacement of the second spring. The construction method of the earthquake-proof wall comprises the following steps that 1, the square framework is constructed, and the anti-bending supports are made; 2, the square framework and the anti-bending supports are connected. According to the earthquake-proof wall and the construction method thereof, when medium and small earthquakes occur, the existing anti-bending supports are mainly stressed and play a main energy consuming function; when a large earthquake occurs, the function of the rigidity enhancement structures is played, the structural rigidity is enhanced, and the structural response is reduced.

Description

technical field [0001] The invention relates to an anti-seismic wall body and a construction method thereof. Background technique [0002] my country is one of the land-earthquake-prone countries. Especially in recent years, large earthquakes have occurred frequently, and the damage to buildings caused by earthquakes has become more and more serious. Reducing casualties and economic losses caused by structural damage is the source of structural engineering technicians. Responsibilities and obligations. The frequent occurrence of earthquake disasters and the improvement of people's demand for life and property protection have put forward higher requirements for the anti-seismic level of buildings. In high-rise and super high-rise buildings, some additional components, such as buckling-resistant braces, are usually installed to increase structural stiffness and overall damping, so as to consume seismic energy and improve seismic safety. In order to prevent the local and overa...
