Cross-floor energy dissipation and seismic mitigation supporting frame structure and construction method thereof

Abstract

The invention discloses a cross-floor energy dissipation and seismic mitigation supporting frame structure which comprises a plurality of supporting frame units, each supporting frame unit is divided into a first zone position, a second zone position, a third zone position and a fourth zone position, and each supporting frame unit comprises two buckling-restrained braces arranged in a linear mode. The buckling-restrained braces are arranged in the first area and the fourth area or the buckling-restrained braces are arranged in the second area and the third area, and the adjacent supporting frame units on the upper layer and the lower layer form a K-shaped supporting frame. According to the cross-floor energy dissipation and seismic mitigation supporting frame structure, the lateral stiffness and the energy dissipation capacity of the frame under the lateral force action such as the earthquake action can be guaranteed, meanwhile, the occupancy rate of the building space is lower, especially in a large-span frame structure with the span-to-height ratio exceeding 2.0, the influence on the building bay size can be greatly reduced, and the construction period is shortened. Meanwhile, the system is higher in integrity and more suitable for large high-rise buildings. The invention further provides a construction method of the cross-floor energy dissipation and seismic mitigation supporting frame structure.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a cross-floor energy-consuming shock-absorbing support frame structure and a construction method thereof. Background technique [0002] In recent years, large earthquakes have occurred frequently, and the damage to buildings caused by earthquakes has become more and more serious. Therefore, reducing the casualties and economic losses caused by the damage of building structures is an important direction in the field of building structure technology. The frequent occurrence of earthquake disasters has put forward higher requirements on the seismic resistance level of buildings. [0003] In high-rise and super-high-rise buildings, some additional components, such as anti-buckling braces, are usually installed to increase structural rigidity and overall damping, so as to consume seismic energy and improve seismic safety. In a high-rise building with anti-buckling bracin...
