A composite steel-concrete section is stronger and stiffer than a steel section on its own. When beams are placed on simple supports, the two materials have a better interaction with each other because the concrete is compressed and the steel is under tension. The steel supporting structure joined by connectors to the upper concrete slab, ensures a unitary static response of the two materials which express their individual characteristics in the best possible way. Composite steel- concrete structures offer numerous advantages from both the mechanical and economic point of view. Tecnaria DIAPASON connectors create and ensure a mechanical bond between the steel beams and concrete slab which together form a composite steel- concrete structure. 15 8.45 Mechanical check of the connector resistance. 15Ĩ.43 Treatment of connector assemblies with insufficient penetration. 14Ĩ.4 Checking the conformity of the connector fastening. 14Ĩ.31 Positioning of the circular disc cartridges. 12 7.4 Influence of ductility on calculation. 12 7.3 Resistance of the connector with steel decking with ribs parallel to the beam. 11ħ.23 Ductility of connectors with steel decking with ribs perpendicular to the beam. 11 7.22 Steel decking different to that tested. 11 7.21 Steel decking that corresponds the that tested. 10ħ.2 Resistance of the connector with steel deck with ribs perpendicular to the beam. 10 7.1 Resistance of the connector in a solid slab. 9 6.2 Composite beams with steel decking. 9Ħ.1 Composite beams without steel decking. 8 5.12 DIAPASON connector with steel decking. 7 3.34 Transverse reinforcements (or mesh reinforcement). 7 3.32 Steel decking (composite floor decks or non-composite). 6ģ.3 Constitution of composite steel beams. 6 3.22 Pin drive and piston for DIAPASON connector. 4 2.4 Uses covered by the specifications.
