Finite element analysis of u-shaped reinforced concrete column

Abstract

Special shaped column is called frame column with special-shaped section. Under the condition of fully considering the strength and stiffness requirements of the whole structure, the U-shaped column is used in the new structural system of contemporary subway architectural pattern, which mainly uses special-shaped column instead of ordinary rectangular column to form the so-called “explicit frame”, so as to promote the interaction between steel and concrete, and greatly improve the bearing capacity of components power. In this paper, the bearing capacity, bending deformation and failure mode of U-shaped reinforced concrete column are analyzed through the finite element software ABAQUS under the change of wall thickness and height, which provides a theoretical basis for the future research on the performance of U-shaped reinforced concrete column.
