Softening of beams near the moment connection can be regarded as one most convenient methods for retrofitting non-seismically designed buildings. This done by drilling beam web (aka RWS–Reduced Web Section) or cutting flanges RBS–Reduced Beam Section). Thus, becoming a cost-effective option and erection new buildings, while optimising use steel; making this high environmental impactful material...

The widespread brittle failure of welded beam-to-column connections caused by the 1994 Northridge and 1995 Kobe earthquakes highlighted the need for retrofitting measures effective in reducing the strength demand imposed on connections under cyclic loading. Researchers presented the reduced beam section (RBS) as a viable option to create a weak zone away from the connection, aiding the preventi...

New composite reinforced concrete beams, in which component is connected to steel T-section, are proposed. The stirrups of the beam were utilized as shear connectors by passing them through drilled holes web T-section. Experimental test and numerical analysis conducted determine behaviour such beams when subjected combined shear, torsion, bending stresses. Full scale one conventional curved pla...

Whilst there has been research about reduced web section beams; RWS, their seismic behaviour when they are overlaid by slabs is not well understood. This study addresses this assessing a high-definition finite element representation of non-seismically detailed RWS connections with slabs. The composite action investigated, focusing on effects the size and location openings. These can reach 4% in...

In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...

The use of perforated (in particular cellular and castellated) beams has become widespread as their manufacturing processes keep minimising wasted material cost-effective by reducing self-weight steel structures, while allowing for larger clear spans. Although behaviour to time-invariant vertical loads been extensively investigated validated in laboratory setups, response reversible actions not...

The article describes the features of work beams with a thin transverse corrugated web plate. Exponential fractional regression is presented, which allows one to estimate relative height plate sections working together flanges, obtained by authors based on an analysis numerical experiments. Based work, method proposed for describing stress state arbitrary cross-section I-beam (the profile corru...
