Description

Types of Steel Columns The two common types of column sections are steel hollow sections (circular, square or rectangular) and I-Beams. Steel Hollow Sections – Steel hollow sections are versatile materials used in commercial, industrial and residential constructions to provide structural support and aesthetic appeal. These hollow steel sections come in either circular (CHS), square (SHS) or rectangular (RHS) shaped cross-sections that possess their own unique properties. CHS steels are commonly used in the construction of columns due to their symmetrical cross-sections. This symmetry is the contributing factor to a CHS ability to resist buckling and increasing strength (Guo et al. 2013). Due to the circular shape of CHS steels, The ends must be flattened in order to join them leading to more time and costs. Additionally, CHS is known for its aesthetic appeal due to the slimmer columns which provide a more spacious feel (Wardenier et al. 2010). RHS steels are comparatively made in rectangular shapes with varying dimensions and thicknesses depending on the requirements and are used in welded steel frames. As a result of this non symmetrical shape, RHS steels experience differing resistance to buckling based on the dimensions and are therefore not as resistant as CHS and SHS steels. In contrast to CHS steel, RHS steel shapes provide it with easier joining methods and greater strength, allowing it to be erected easily. Much like CHS steel, SHS steel has the benefit of being symmetrical in cross-section and therefore possess similar buckling resistance and strength as CHS. SHS steel also has flat faces lending to easier joining between members much like RHS. However, is not as resistant to buckling or strong as CHS steel. With this being said, it is clear that a mixture of high strength and buckling resistance, and efficient member joining must be considered when choosing section types. I Beams I beams are a structural engineering material often used in a buildings essential supports and to ensure a structure’s integrity whilst reducing material cost and construction time. They are also referred to as H-Beam, universal beam or W-beam and consist of a large vertical section (Web) connected to two smaller horizontal sections (flange). The I beam’s web provides a strong resistance to shearing whilst the flanges allow it to resist bending. In doing this, the I beam is able to more efficiently...
