EXPERIMENTAL AND ANALYTICAL STUDY ON THE IMPACT BEHAVIOR OF STEEL–CONCRETE COMPOSITE SLAB

Concrete structures have been widely used for many years to resist impact loads. Steel–concrete composite may be considered efficient in the emerging modern construction field. Hence, main objective of this research was study behavior steel concrete slabs with different shear connectors and compare them conventional slabs. Seven specimens dimensions 500 × 50 mm were cast, which included plain cement slabs, two reinforced mesh rebars as reinforcement, four steel-concrete connectors: stud, tee, angle, channel connectors. The action achieved using a decking sheet welded on layer poured at top. test setup fabricated slots provided simply supported end conditions mild drop weight. impacted center span by dropping mass from free fall height 1 m. number blows corresponding initial cracking ultimate failure stages recorded. parameters that energy absorbed, crack pattern, width, increase first blow last blow. experimental results very close analytical obtained ANSYS. showed performed better than others, it proven under loading
