Abstract
To make the use of steel beams with openings in the web for construction of industrial buildings, high rise building, has turn out to be extensive in modern times. There are numerous reasons for which openings are kept. Various popular openings shapes are, hexagonal, circular and rectangular. Due to openings in the web the behaviour of such beam is different than that of plain-webbed beams. The various parameters which influence the behaviour of such special type of beams are shape of openings, size of openings, spacing of openings, aspect ratio, various numbers of openings and reinforcement (stiffeners). Therefore this paper presents the detailed experimental and finite element investigation on optimisation of spacing to diameter ratio of steel beams with web openings. Five models have been tested having different spacing to diameter ratio of openings for direct comparison. Spacing to diameter ratio of openings in the range of 1.33-1.6 found to very effective.
