Embedded type steel high-ductility fiber concrete combination column

Abstract

The invention discloses an embedded type steel high-ductility fiber concrete combination column, and solves the problems of easiness in having longitudinal shear slip damage of the conventional profile steel concrete combination column due to brittleness, lower tensile strength, lower shearing resistance and lower bending strength of the concrete material, poor adhesive property between the concrete and profile steel, and poor anti-cracking ability and non-deformability. The embedded type steel high-ductility fiber concrete combination column comprises profile steel, high-ductility fiber concrete embedded in the profile steel, and a shear connector arranged between the profile steel and the high-ductility fiber concrete. The embedded type steel high-ductility fiber concrete combination column, provided by the invention, has better anti-cracking ability, non-deformability, stability, anti-seismic property and adhesive property of the concrete and the profile steel than the conventional steel reinforced concrete combination column, and the profile steel is exposed, so that the profile steel and an adjacent member are connected conveniently.

Description

technical field [0001] The invention relates to an embedded steel high ductility fiber concrete composite column, in particular to an embedded steel high ductility fiber concrete composite column. Background technique [0002] Steel-concrete composite columns are widely used in large-scale industrial buildings and high-rise and super-high-rise civil buildings in my country. Poor joint performance, prone to longitudinal shear slip damage, unfavorable to the earthquake resistance of the structure, and difficult to repair after the earthquake. Therefore, due to the brittleness of the concrete itself, when the deformation of the component is large, the concrete is destroyed before the section steel, so that the existing steel-concrete composite column medium-section steel cannot give full play to its excellent performance, resulting in poor crack resistance of the composite column and prone to longitudinal shear. Its application in high-rise building structures is limited due to...

[0002] Steel-concrete composite columns are widely used in large-scale industrial buildings and high-rise and super-high-rise civil buildings in my country. Poor joint performance, prone to longitudinal shear slip damage, unfavorable to the earthquake resistance of the structure, and difficult to repair after the earthquake

Therefore, due to the brittleness of the concrete itself, when the deformation of the component is large, the concrete is destroyed before the section steel, so that the existing steel-concrete composite column medium-section steel cannot give full play to its excellent performance, resulting in poor crack resistance of the composite column and prone to longitudinal shear. Slip damage, and the high cost of post-earthquake repairs limit its application in high-rise building structures.
