The structural adequacy of DECK sections is established by choosing the section to provide requisite sectional modules to satisfy moment and deflection criterion. A moment coefficient of 1/8 is used for single and dual spans and 1/10 for 3 or more spans. The deflection co-efficient are 0.013 for single span and 0.0078 for multi spans. The maximum deflection of the DECKSHEETS is restricted to L/250 under uniformly distributed loads.
The standard mezzanine system consists of a steel deck support by joists onto main mezzanine beams. If required by design loads, the main beams shall also be supported by intermediate columns. The top flange of the joists fit immediately below the top flange of the primary beams.
- The embossments on the top and the sides of the ribs provide added grip and minimise slip by creating a bond with concrete as done with normal reinforcement.
- It provides permanent form work as well as positive reinforcement. No erection, removal, handling or storage of timber / steel form work as in conventional concrete slab construction, saving valuable time.
- Clean, uniform and attractive ribbed underside for exposed situation reduces the cost of ceiling finishes.
- MS deck sheet is provided for suitable load on the floor and covered with form concrete.
