| [en] Composite slabs lead to slim and economic structural solutions with a low selfweight. The determination of their moment resistance follows the regulations presented
in EN 1994-1-1 (2004) which are based on plastic design methods. The current version of Eurocode 4 does not consider explicitly additional reinforcement in the ribs for sagging moment resistance. However, the construction industry requires this possibility in order to provide economical and flexible design. Regarding this situation, further investigations are necessary to prove the applicability of plastic design methods. In the case of high bottom reinforcement ratio, a deep position of the plastic neutral axis occurs, and concrete compression failure may happen before most parts of the profiled steel sheeting and reinforcement yield. This leads to an overestimation of the bending resistance according to the plastic design method. A parametric study, based on approximately 290.000 different combinations of various cross-section geometries and materials, is provided to compare the plastic moment resistance with the resistance determined by strain-limited design. The results show that limitations are necessary to be enabled for the general application of plastic design methods. | |
