Confined concrete combination column

Abstract

The invention discloses a confined concrete combination column. The confined concrete combination column comprises square steel pipe columns, U-shaped steel pipe columns, L-shaped steel pipe columns and concrete columns. One square steel pipe column serves as a benchmark column, the U-shaped steel pipe columns are sequentially welded along the adjacent edges of each benchmark column, the L-shaped steel pipe columns are sequentially welded along the adjacent edges of each U-shaped steel pipe column, and a steel pipe bundle is formed; and all the square steel pipe columns of each steel pipe bundle are filled with concrete finally, so that the confined concrete combination column is formed. According to the confined concrete combination column, the defect that the ductility and the energy-dissipating capacity of a traditional reinforced concrete column are poor is overcome; meanwhile, the steel pipe concrete section form is improved, so that the bearing capacity of the confined concrete combination column is greatly improved, and the application range of the confined concrete combination column is greatly expanded; construction is convenient; the seismic resistance of the column is greatly improved; and the confined concrete combination column is suitable for being applied to high-rise buildings and buildings in areas high in seismic intensity.

Description

technical field [0001] The invention relates to a novel steel-concrete composite column, in particular to a novel restrained concrete composite column. Background technique [0002] Column is an indispensable key component in all building structure systems, and has always been the key component of civil engineering scholars at home and abroad. At present, a lot of research work has been carried out on reinforced concrete columns and steel tube concrete columns. It has become one of the main directions of column research to increase the bearing capacity of components and improve the mechanical properties of columns by improving the performance of column reinforcement or steel pipes. In recent years, the vast majority of structures in my country still use reinforced concrete columns, but studies have shown that although the comprehensive performance of reinforced concrete columns has been improved under various new reinforcement schemes, the comprehensive seismic performance a...
