Comparison of steel-concrete composite column and steel column
Composite Structures, 2018Abstract The aim of the work was numerical analyses of a steel-concrete composite column and a steel column. An internal column 3.60 m in length was considered. The column was on the second storey of a six-storey building designed for retail and services. The column was subjected to compression and uniaxial bending. The existing steel column was made

Comparison of Conventional RCC Columns, Steel Columns and Composite Columns
Journal of Structural Engineering and Management, 2023Worldwide, the steel industry is expanding almost everywhere. Compared to the USA, EU, and other developed nations, India uses less steel in the construction industry. Additionally, India's cities have some of the highest population densities per square kilometre, which limits horizontal construction growth and favours vertical development.

Simulation of partially encased composite steel–concrete columns with steel columns
Journal of Constructional Steel Research, 2007Abstract This paper presents a method for simulating composite steel–concrete columns of double-symmetrical, partially encased cross-sections, as equivalent steel columns of fictitious cross-section, for the purposes of linear elastic analysis. The latter consist of the actual steel cross-section and two additional pairs of plates, one perpendicular ...

Castellated cruciform steel columns
World Journal of Engineering, 2018Purpose The main function of the castellation process is making I-sections stiffer by increasing the height of web and supplying a higher moment capacity of primary axis than plain-webbed members of the same weight. In addition, it optimizes the use of heavy, costly constructional steel material and provides good services accessibility. The purpose of

Abstract This paper uses a simple model to unify the two traditional approaches to steel column strength based either on the buckling of straight columns with residual stresses or on the first yield of crooked columns. The inelastic buckling and post-buckling loads of elastic-plastic-strain hardening steel columns with residual stresses are ...

End tie plates in battened columns may contribute significantly to the buckling strength. Their effect is accentuated by the study of a spaced column, defined herein as the limiting case of a battened column in which the battens are attached to the longitudinal column elements by hinged connections. The strengthening effect of the end tie plates is due

Column Curves for Stainless Steel Alloys
Journal of Constructional Steel Research, 1999Abstract The paper describes a column curve formulation capable of producing accurate strength curves for cold-formed stainless steel columns. The formulation uses a non-linear expression for the imperfection parameter but is otherwise identical to the Perry–Robertson equation used in Eurocode3, Parts 1.1, 1.3 and 1.4. It is shown that several column

Fabricated Tubular Steel Columns
Journal of the Structural Division, 1980The Newton-Raphson iterative technique is used to model the strength and behavior of axially loaded, fabricated, tubular, steel columns. Such columns characteristically have highly variable section properties along their length, due in part to the residual stresses introduced by the longitudinal welding process. The analysis developed is used to derive

Steel Core in Composite Steel-Concrete Columns
Key Engineering Materials, 2016This paper presents some results of theoretical and experimental investigations of composite steel-concrete columns with solid steel profiles - steel cores. Due to absence of simplified design method according to EN 1994-1-1 [1], design of these columns in practice is limited in general. Reasons for this are residual stresses in steel profile caused by
