Meshless local buckling analysis of steel beams with irregular web openings

In addition to typical perforated beams with regular openings of circular or hexagonal holes, the use of beams with irregular web holes of different shapes and arrangement is also widespread in steel construction. Despite some advantages over typical perforated beams, the behaviour of such beams is...

description In addition to typical perforated beams with regular openings of circular or hexagonal holes, the use of beams with irregular web holes of different shapes and arrangement is also widespread in steel construction.
