Connections: 5% of beam + column weight.Columns size: average weight of column stack averaged per storey assuming a 6 storey structure.75m c/c beams – slab: 140mm thick slab using 60mm re-entrant deck.5m c/c beams – slab: 140mm thick slab using 50mm re-entrant deck.The particular parameters reviewed are as follows: A further allowance for connection steelwork.We are now pleased to extend the study with due consideration of the following additional aspects of the grid: So whilst informative with respective the floor steelwork, there was no review of the impact of slab type and column size, which are clearly integral components of the grid or bay under review. The drawback of the grid study was its restriction to a straightforward review of the steelwork only, i.e. Longer-spanning solutions using Westok ribbon-cut beams offered lighter floor steelwork intensities than alternatives on a shorter grid.For all design scenarios considered, the Westok ribbon cut beam offered the lightest solution.The study detailed the arising floor-plate steel kg/m2 and A1-A3 embodied carbon kgCO2e/m2 for the different forms of cellular beams manufactured by Kloeckner Metals UK Westok.
