The calculation of deck structure applied in the construction of pre-engineered factories is a trend because of its convenience and suitable and safe design in all construction conditions at the construction site. Besides, it is still necessary to save the cost of the item in the most optimal way when using the deck.
Before learning how to calculate deck structure, it is necessary to know some outstanding features of the floor and the design process so that a suitable calculation can be made.
Deck deck is a combination of steel and bearing concrete. Profiled steel composite and covered with concrete in whole or in part. The deck is placed on top of the steel beams, and corrugated steel sheets placed on the underside of the concrete surface act as a support during the construction process. Anchor pins increase the bond between concrete and steel. The special structure of the deck slabs always ensures the construction progress.
The designer will choose the shape and size of the column beam slab and the associated frames. Analyze the structure of the building to determine the internal force capacity as well as the degree of the structure. During the analysis, it is necessary to pay attention to the calculation of including the width of the floor slab into the floor beam structure.
Deck deck, also known as composite deck, so most calculations will be based on European standards. When calculating according to this standard, special attention should be paid to using concrete from M350 and above.
Total thickness of composite slab >= 80mm and up to 180mm
Concrete with a thickness greater than 40mm to be able to bear the load and protect the reinforced floor slab inside. Floor slab span from 2.5m to 4m or 7m in case of supporting pillars.
Outline drawing that determines the total length and width of the surface area to be used for the deck. Completing detailed drawings, adjusting the design draft paying attention to the inclination, distance with beams, construction conditions and topographical conditions at construction site. Temporarily determining the size of the deck will use choosing a deck with a suitable design in terms of thickness, height and size of the corrugated board, as well as determining whether the concrete extract has enough bearing capacity. For horizontal designs add 10% material for inclined designs add 15% material to avoid loss errors.
Calculating the distance need to subtract the distance between the beams and columns to save materials and costs in the most optimal way
Calculation of the total quantity applying the formulas for load deflection and limit state shear resistance depending on the structure of the building.
