Reinforced concrete split column with core

Abstract

The invention relates to a reinforced concrete split column with a core, which belongs to the technical field of construction engineering. The reinforced concrete split column with the core adopts partition boards as filling materials to divide an integral section concrete frame column into unit columns along the vertical direction, and a core column which consists of a column core stirrup and a column core longitudinal bar is further arranged at the middle part of a steel reinforcement cage which is composed of an ordinary longitudinal bar and an ordinary stirrup of each unit column. The reinforced concrete split column with the core can simultaneously improve the vertical bearing capacity and the lateral deformation capacity, improve the aseismic capacity and increase the using area of a building under the same size of the section.

Description

technical field [0001] The invention relates to a reinforced concrete split column with a core. It belongs to the technical field of construction engineering. Background technique [0002] At present, the reinforced concrete core column used in construction projects can effectively improve the axial pressure and deformation capacity of the column and reduce the compression of the column because the core steel bar participates in the work. Moreover, when the concrete around the column is cracked, spalled or even damaged, Since the longitudinal reinforcement of the core column does not buckle and maintains a good bond with the concrete, the frame column can still continue to resist the vertical load and prevent the structure from collapsing under a large earthquake, but the reinforced concrete has the ability of the core column to move laterally. Still poor, prone to shear failure. Although the reinforced concrete split column can improve the lateral displacement deformation...

[0002] At present, the reinforced concrete core column used in construction projects can effectively improve the axial pressure and deformation capacity of the column and reduce the compression of the column because the core steel bar participates in the work. Moreover, when the concrete around the column is cracked, spalled or even damaged, Since the longitudinal reinforcement of the core column does not buckle and maintains a good bond with the concrete, the frame column can still continue to resist the vertical load and prevent the structure from collapsing under a large earthquake, but the reinforced concrete has the ability of the core column to move laterally. Still poor, prone to shear failure

Although the reinforced concrete split column can improve the lateral deformation capacity of the reinforced concrete short column, it has no obvious improvement effect on the axial compressive bearing capacity, and increases the cross-sectional area of ​​the column.
