Cracking of concrete The lower surface of the slab is protected by the sheeting. Cracking will occur in the top surface where the slab is continuous over a supporting beam, and will be wider if each span of the slab is designed as simply-supported, rather than continuous, and if the spans are propped during construction. For these reasons, longitudinal reinforcement should be provided

Tag: Composite slabs Resistance of composite slabs to longitudinal shear

For profiled sheeting that relies on frictional interlock to transmit longitudinal shear, there is no satisfactory conceptual model. This led to the development of the shear-bond test, described in Section 2.8.1, and the empirical ‘m-k’ method of design, where the shear resistance is given by an equation based on (2.33), in the British code or on equation (2.32), in Eurocode 4. With the

The width of slab considered in calculations, b, is usually taken as one metre, but for clarity only a width of one wavelength is shown in Fig.3.2. The overall thickness hs is required by Eurocode 4 to be not less than 80 mm; and the thickness of concrete above the ‘main flat surface’ of the top of the ribs of the sheeting, to

Tag: Composite slabs Composite beams and slabs

The design of structures for buildings and bridges is mainly concerned with the provision and support of load-bearing horizontal surfaces. Except in long-span bridges, these floors or decks are usually made of reinforced concrete, for no other material has a better combination of low cost, high strength, and resistance to corrosion, abrasion, and fire. The economical span for a reinforced concrete slab is
