Fully Fabricated Steel Frame Structural System with Restoration

Abstract

The invention relates to the technical field of architecture structural components, and discloses a total assembled steel framework structural system with a restoration function. The total assembled steel framework structural system comprises independent foundations and a plurality of beam column joints. The beam column joint at the center comprises sleeve type steel pipe columns, each sleeve typesteel pipe column comprises a square steel pipe column and an inner circle steel pipe column. The beam column joint not at the center comprises round steel pipe columns, each round steel pipe columncomprises an upper section steel pipe column, a central plug-in column and a lower section steel pipe column. H-shaped steel beams are connected with the round steel pipe columns through sleeve connection parts. Structural system bodies at the same layer form a whole through connection of the two ends of each H-shaped steel beam and the round steel pipe columns or the square steel pipe columns. The sleeve steel pipe columns at the upper layer and the lower layer are connected with each other through double-sleeve type connection parts. The round steel pipe columns at the upper layer and the lower layer are connected through splicing bases. The structural system cannot be destroyed under the effect of small earthquakes, can self restore under the effect of middle earthquakes, and does not collapse under the effect of major earthquakes, components can be rapidly replaced, thus the usage function can be restored, and an innovation of a self restoration type anti-seismic structural systemis achieved.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to a fully assembled steel frame structure system with recovery function. Background technique [0002] How to make the engineering structure, the whole city and even the whole society have the ability to recover function (Resilience) after the earthquake has aroused the close attention of the earthquake engineering field in recent years. Recoverable functional structures mainly include swing wall or swing frame structure, self-resetting structure and replaceable structure. Studies have shown that the sway of the structure can reduce the earthquake action and the ductility design requirements of the structure itself, reduce the earthquake damage, and save the cost. Through the constraints between the structure and the foundation or between the components, the contact surface between the structure and the foundation or components can only bear Under the action...
