Table of mechanical properties and allowed loads for composite slabs TR 100/250
H: Floor slab, t: thickness, P: Floor slab weight, Χs: C.C.distance from the top surface, Jtot: Moment of inertia for the total section, Ws: Section modulus for top surface, Wj: Section modulus for bottom surface, Τ: Maximum working shear limit of the floor slab (kg/m), Trapezium surface S=0,00877m2 or S'=0,03507 m2/m of width.
Α: SINGLE SPAN, Β: MULTIPLE SPAN.
ΝΟΤΕ: The values of the tables should be used only during pre-study stage. For detailed calculations engineer must carry out his own study.
To avoid cracking and for better load distribution, we advise laying an electrically welded grid 2cm from the upper surface of the concrete. Casting is performed by firstly trying to deposit the concrete at the supports and then by distributing it in a gradual way. The use of struts to the middle of each bay is recommended until the concrete gets solid.

Composite slabs TR 100/250
The high bearing capacity corrugated metal sheets DOMOLAM, are produced in a wide range and are used in composite slabs and permanent metal reinforcements for industrial and residential constructions. The collaboration between the metal sheet and the casting (concrete) is achieved through embossments capable of anchoring the casting impeding its detachment. The worked sheet therefore acts both as formwork during casting and as reinforcement, allowing the composites labs to carry higher loads in comparison to the traditional floors. They are produced in thickness up to 2,00mm according to EN 1090-1:2009+A1:2011 and have CE marking.
Composite slabs metal sheets points of excellence
1. Easy installation and modifications through cuts, additions, welding and nailing even on existing cunstructions.
2. Less weight construction for the same payload.
3. Shorter construction time overall, because of the possibility of simultaneous work on different floors.
4. Lower transportation cost in relation to other
traditional precast elements.
