Concrete Encased Steel Composite Columns: A Review

EasyChair Preprint 4683

Abstract

Concrete Encased Steel composite columns are those columns in which structural steel is encased inside reinforced concrete. By combining both materials, columns can handle a large amount of load with a lesser cross sectional area. Moreover, they improves overall rigidity of the building and provide significant resistance to lateral loads. These columns are widely used in high rise building constructions. Main disadvantage of these columns are the construction difficulties. Since reinforcement bars and steel sections are encased, the concrete pouring becomes more difficult. Solution for these problems are the use of welding couplers or providing holes in steel flanges and web. Both the methods will increase the cost of construction and also compromise the total bearing capacity and reliability of the structure. An innovative method proposed to overcome these difficulties is the use of steel fibres and replacing the reinforcement bars. This paper discuss various studies conducted on concrete encased steel composite members.
