Shape memory alloy energy consumption combined column with resetting function and mounting method thereof

Abstract

The invention relates to a shape memory alloy energy consumption combined column with a resetting function and a mounting method thereof and belongs to the technical field of structural projects. Theshape memory alloy energy consumption combined column comprises a foundation, assembled square steel pipe columns, I-shaped columns, H-shaped steel beams, anti-buckling supports and connecting short beams, T-shaped splicing plates are fixed to the joint area parts of the assembled square steel pipe columns, and grooves are formed in the upper portions and the lower protons of the T-shaped splicingplates correspondingly. The T-shaped splicing plates and the assembled square steel pipe columns are connected by self-locking bolts, the joint area parts of the I-shaped columns are connected by resetting joints, and the middle of each layer of each I-shaped column is connected by three splicing plates through bolts. Shape memory alloy long bolts are arranged between the upper flanges and the lowerflanges of the I-shaped columns, one ends of L-shaped connecting plates are fixedly connected with the connecting short beams, the other ends of the L-shaped connecting plates are fixedly connectedwith the H-shaped steel beams, and ribbed plates are welded to the corresponding positions of the columns. The anti-buckling supports between the assembled square steel pipe columns and the I-shapedcolumns are connected in a combined mode. According to the shape memory alloy energy consumption combined column with the resetting function and the mounting method thereof, the effects that completeassembling is conducted on a construction site, energy dissipating can be achieved in an earthquake, and the after-earthquake restoring capacity is improved are achieved.

Description

technical field [0001] The invention relates to a resettable shape-memory alloy energy-dissipating combined column and an installation method, belonging to the technical field of structural engineering. Background technique [0002] With the development of technology, the height and span of building structures continue to increase. In towering, long-span frame structure buildings, the frame skeleton composed of beams and columns is the main load-bearing structure failure form, usually shear failure. In actual design, the axial compression ratio of the column needs to be strictly controlled to ensure safe bearing under earthquake action. When the axial compression ratio is relatively large, the adjustment method usually adopted in the design is to increase the section of the column and set up a horizontal shear resistance system (such as shear walls and column supports, etc.). In the residential structure, the traditional frame structure columns usually adopt square and rect...
