The above design examples show that a practical thin floor system can be designed and constructed. In both examples, approximately 7 to 9 inches in total girder depth can be saved for most commonly used beam and girder spans. The system utilizes all the elements of conventional composite steel-concrete construction,
Together they manifest the most efficient ratio of cost and performance. Construction industry is constantly searching for faster production and cheaper structures. Reinforced concrete with profiled sheets as permanent shuttering is exactly such an example. 3.1. The structure. The flooring composite slab is made of concrete,
Such slabs are generally used in frame structures, with steel floor beams, as discussed previously in Lecture 10.1. They can also be used in combination with other materials. In this type of construction the profiled sheet has several functions: it provides a working platform for construction. it acts as formwork for the concrete
A structural member composed of two or more dissimilar materials joined together to act as a unit in which the resulting system is stronger than the sum of its parts. An example in civil structures is the steel-concrete composite beam in which a steel wide-flange shape (I or W shape) is attached to a concrete floor slab.
We have a composite floor supporting large process tanks via lugs in the center of several bays. The lugs are on For example, ought I put in the transformed beam area instead of the steel beam area? B - For unshored composite beam design, some of the deflection occurs before the beam is composite and some after.

DACS Non-Composite decks are used when only a form for a concrete slab is desired. Our three non-composite decks are "S" deck, or commonly known a "form deck" or 9 16" form, "HD" or 7 8" and B-deck inverted. Similar to composite deck, the determining factors for selecting the proper non-composite deck is the depth of
This paper presents the structural behavior of composite concrete slabs with CRIL DECKSPANTM (Colour Roof India Limited (CRIL), Mumbai, INDIA) type profiled steel decking by experimental and analytical studies. The slab is created by composite interaction between the concrete and steel deck with embossments to
The decks are suitable for conventional composite construction where the deck is placed onto the top flange of the steel support beam. Deep composite floor decks. ComFlor 210 and ComFlor 225 are both designed to be used with the Tata Steel. Slimdek system, which uses asymmetric beams. The floor deck lands on
composite beam. Composite beams are similar to concrete T-beams where the flange of the T-beam is made of concrete slab and the web of the T-beam is made of the An example of this is composite metal deck with concrete fill, steel filler In a composite floor system the concrete acts together with the steel to create.
beams composite. They are not necessary to make the deck composite but they enhance the load capacity of the composite slab - as an example 3”. 20 gage Lok Floor (40 ksi yield) with a 5.5” 3 ksi normal weight concrete slab has the following factored LRFD nominal moments: At times shear studs are not used to.

"composite steel deck floor slab" is applied to systems in which the steel deck has some mechanical means of providing positive interlocking between the deck and the concrete.
