Fig. 3.(a) Slim-floor construction with deep composite decking, (b) Slim-floor construction with precast concrete slab [8]. To increase the span of the slim-floor beams a new shear transfer technology is known as concrete dowels shear connection which connects the slim-floor beam (SFB) wit...
ConcreteSlabSteel deckingSlipIn this study, mechanical behavior and failure pattern of composite concrete deck were investigated. A unique dimension of steel concrete deck was fabricated and tested in four-point bending. Two series of decking were also designated with bolts at a spacing of 15 cm ...
For application of any of these methods, tests of a fragment of floor (simply supported composite slab) should be carried out and for this reason designers and constructors have to apply to specialised laboratories. Moreover, for concrete of a tested fragment, storage conditions of the specimens...
The present technology relates generally to a platform and concrete composite slab system used as a building material. A platform, is formed from joined, substantially coplanar boar
The composite joist floor system includes joists supporting metal decking and a stand-off fasteners are spaced along the length of the joist Each fastener has an upper portion with
The scientific and reasonable mechanical design enables steel truss floor decking to meet the 5M unsupported large span design requirements.During the actual construction process and before the concrete is poured,a simple temporary support can be set in the slab span to...
Composite action between the concrete slab and steel beam in a building frame is typically achieved by using headed stud shear connectors that are welded to the top flange of the steel beam to produce robust shear connection, but their demolition necessarily is associated with much waste and uses...
Concrete; Bridge deck; Composite structures; Effective flange width; Finite element analysis 1. Introduction The United States (US) has one of the largest highway networks in the world. The efficiency and safety of this net- work plays an essential role in the continued economic vitalit...
Profiled steel decking forms the underside to the concrete floor construction and is directly exposed to heat. Fire tests on isolated slabs has shown that the composite slab can achieve up to 120 Modern fire protection methods There are various methods of protection for steel structures: Spray or...
6, which was equivalent to the 0.2% minimum reinforcement in the concrete topping according to Eurocode 4. It was positioned 40 mm from the top of the slab, as shown in Fig. 5, so that it was just below the head of the shear connectors. The decking was discontinuous at the internal...
