Abstract: A new design model is presented to derive expressions for the elastic effective length factors for columns in unbraced multistory frames. This model takes into account the effects of boundary conditions at the far ends of ...

Abstract: A new set of effective‐length factors is presented for designing doubly symmetric I‐shaped built‐in cantilever beams against lateral‐torsional buckling when subject to different loading and restraint conditions at the ...

Abstract: In cantilever-suspended-span construction, secondary framing members such as open-web steel joists are likely to enhance markedly the stability of the beams that support them. Properly made joist-beam connections enable ...

Abstract: A series of 18 large-scale tests was carried out on corrugated cold-formed steel deck diaphragms for single-story buildings to investigate the diaphragm’s ability to function as the main source for absorbing earthquake ...
