2mm/m for level variance.

3/8 inch OSB, 24/0, 30 psf live load max 9mm

1 1/8 inch OSB, 48 oc, 290 psf live load max 28mm

125 psf live load or an 8,000 lb point load on the concrete slab

According the IBC 2006, I need to design for a 40 PSF uniform live load or 3000 psf concentrated live load for passenger vehicle parking garage floors. Concentrated load of 3 kips 

Solution: 4 layers of 18mm plywood laid cross pattern and glued with resorcinol formaldehyde glue.

Functional Requirements of Floors in Building Construction

• Following are the functional requirements of floors in building:
• Strength and stability
• Resistance to weather and ground moisture
• Durability and free from maintenance
• Fire resistance
• Resistance to passage of heat
• Resistance to passage of sound

The strength of floor structure should be adequate to carry dead load of the floor, finishes, fixtures, partitions, services and expected imposed loads of occupants. Design loads for building can be found in both Minimum design loads for buildings and other structures (ASCE/SEI 7-10) and BS 6399: Part 1.

The stiffness of floor should be enough to make the floor stay stable and level under its self weight and expected dead and live loads. Furthermore, the floors need to support and accommodate ventilation, water, electrical, heating services without causing detrimental effect on the stability of the floor. The deflection of the floor must be adequately restricted and kept small to prevent cracking of rigid finishing.

Floors should withstand fire for enough period during which the occupant can get out of the building.
