Construction stage reliability of composite steel deck designed according to Canadian Standard.

- Abstract
A reliability-based evaluation of the CSSBI 12M provisions for composite steel deck in the construction stage is presented. Deck reliability was analyzed for strength and deflection limit states with first-order reliability method for a large number of slab configurations typically used in North America. The results demonstrate that reliability indices for about 31% of all considered cases do not meet the CSA S136 requirements. Modifications of the CSSBI 12M construction loads are presented. The revised construction loads result in reductions of maximum unshored construction spans by 3% on average (with a maximum reduction of 7%) and better deck reliability, which meets the CSA S136 requirements and is more uniform across the typical design parameters when compared to the current design provisions.
