Yield Line Design for SFRC Elevated Slabs

The paper aims at discussing the application of Yield Line methods for the design of elevated slabs made of Steel Fibre Reinforced concrete. The paper considers three different case studies of Fibre reinforced concrete slabs ranging from laboratory small case test to real scale application. In particular, three different slabs are considered: circular simply supported slab (diameter 60 cm and thickness 2 cm), two different configurations of centrally loaded slabs with four point supports with 2 m span and a real scale elevated slab on columns with clear span of 6 m and nominal thickness of 20 cm. The paper discusses the approach that is going to be proposed by the Annex L of Eurocode 2 for the design of FRC structures and particularly compare the results of such a design approach and the experimental results.
