Abstract

The invention discloses an earthquake damage replaceable combination column structure which comprises a core square steel pipe, a ground beam end plate and four replaceable steel boxes. The core square steel pipe is arranged on the ground beam end plate, the lower end of the core square steel pipe is closed, the upper end of the core square steel pipe is fixedly connected with an RC column through a plurality of first fixedly connecting structures and provided with an opening containing the lower end of the RC column, the ground beam end plate is fixedly arranged on a ground beam through second fixedly connecting structures, and the four replaceable steel boxes are detachably arranged on walls of the core square steel pipe respectively to surround the core square steel pipe. After an earthquake, only the peripheral replaceable steel boxes can be subjected to buckling failure, the core square steel pipe is only slightly destructed or not destructed, controllability of a destruction position is realized on the premise of ensuring vertical bearing capacity, earthquake resistance is excellent, the column is reset after the earthquake, the replaceable steel boxes are detached and replaced by intact steel boxes, and the structure is rapidly repaired after the earthquake.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an earthquake-damaged replaceable composite column structure. Background technique [0002] Realizing rapid repair of structural earthquake damage and rapid restoration of building functions is an important topic in the field of earthquake engineering research today, and it is also a new requirement and challenge for the innovation of assembly structure systems to achieve sustainable development of building industrialization. But so far, research in the field of recoverable performance structures has mainly focused on the replaceable energy-dissipating coupling beam technology of shear walls and self-resetting shear wall structures. For example, the Chinese invention patent CN201220411822.5 proposes a new type of joint shear wall structure, including the wall and its connecting beam; the connecting beam includes end beams at both ends and a middle bea...
