Flat double layer grid (DLG) structures are efficient modular, structural systems which span in two or more directions and consequently develop their resistance in three dimensions. Although such structures offer many structural, constructional and aesthetic advantages over alternative planar structures, for use in unobstructed roofing applications, they have been observed to have a propensity for sudden collapse behaviour, as witnessed in the collapse of the Hartford Coliseum roof structure in 1978. Previous study of DLG behaviour has been undertaken through experimental and numerical analysis; these studies have confirmed the sudden collapse behaviour and sensitivity of such structures to geometric imperfections for selected cases but have not developed the full spectrum of DLG behaviour. A parameter study was therefore undertaken to identify desirable DLG pre-critical yielding behaviour and post-critical increases in grid structural resistance. The parameter study also served to identify and characterize grid plastic, failure and collapse behaviour for structures representative of those employed in practice; the Structural Eurocodes were used for this purpose. 2015-02-03T18:28:55Z 2015-02-03T18:28:55Z 2012 Master Thesis Masters MSc http://hdl.handle.net/11427/12341 eng application/pdf Department of Civil Engineering Faculty of Engineering and the Built Environment University of Cape Town |
