Abstract

The invention discloses a self-resetting swing steel frame structure, which comprises: a foundation piece, a steel column, a column base node structure, a beam end node structure, and an intermediate beam; wherein, two base pieces and two steel columns are arranged respectively; Arranged directly on the top of the foundation; the node structure of the column base includes: column base high-strength anchor rod, column base disc spring, cantilever plate; the cantilever plate is fixed on both sides of the steel column near the bottom; column base high-strength anchor rod passes through The cantilevered plate is fixedly connected to the top of the foundation; the disc spring at the base of the column is set on the high-strength anchor rod at the base of the cantilevered plate away from the base; the middle beam is arranged horizontally and fixed between two steel columns. The steel frame of the invention has extremely strong self-resetting performance and energy dissipation capacity, and also has excellent ductility and fatigue resistance.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of building structures, and more specifically relates to a self-resetting swing steel frame structure and a construction method thereof. Background technique [0002] At present, the traditional anti-seismic thinking takes protecting life as the primary goal, and prevents structures from collapsing under strong earthquakes through ductile design. However, this ductile design comes at the expense of allowing plastic deformation of the main stressed members of the structure. On the other hand, the structure may be subjected to earthquakes stronger than the fortification intensity during use, which will also cause damage and residual deformation of the structure. In fact, earthquake disasters in recent years have shown that the number of building collapses and casualties in earthquakes has been effectively controlled, but the economic losses and social impacts caused ...
