Collapse behaviour of double-layer grid structures in steel
J.M. Adams & A. Zingoni
University of Cape Town, Cape Town, South Africa
ABSTRACT: The propensity of double-layer grid (DLG) structures to fail suddenly, without warning, has
contributed to their reduced popularity in industry. To identify DLG pre-critical yielding behaviour and the
increases in DLG post-critical structural resistance, which represent improvements to conventional DLG failure
behaviour, a structural and geometric parametric study was undertaken of DLG symmetric collapse under
distributed loading. Finite element modelling ...
