Abstract
Purpose – Due to the enormous increase in economic development, structural steel material gives an advantage for the construction of stadiums,
factories, bridges and cities building design. The purpose of this study is to investigate the behaviour of bending, buckling and torsion for I-beam
steel section with and without web opening using non-linear finite element analysis.
Design/methodology/approach – The control model was simulated via LUSAS software with the four main parameters which included opening
size, layout, shape and orientation. The analysis used a constant beam span which is 3.5m while the edge distance from the centre of the opening
to the edge of the beam is kept constant at 250mm at each end.
Findings – The analysis results show that the optimum opening size obtained is 0.65 D while optimum layout of opening is Layout 1 with nine web
openings. Under bending behaviour, steel section with octagon shapes of web opening shows the highest yield load, yield moment and thus highest
structural efficiency as compared to other shapes of openings. Besides, square shape of web opening has the highest structural efficiency under
buckling behaviour. The lower buckling load and buckling moment contribute to the higher structural efficiency.
Originality/value – Further, the square web opening with counter clockwise has the highest structural efficiency under torsion behaviour.
