A flat piece of concrete, put on the walls or columns of a structure. It serves as a walking surface but may also serve as a load bearing member, as in slab homes.
Functions of Concrete
Design Considerations in Slab:
- Locate position of wall to maximize the structural stiffness for lateral loads
- Facilitates the rigidity to be located to the center of building
- Its necessary to check the slab deflection for all load cases both for short and long term basis. In general, under full service load, Deflection (δ) < L/250 or 40 mm whichever is smaller.
- Its preferable to perform crack width calculations based on spacing of reinforcement.
- Good detailing of reinforcement will
- Restrict the crack width to within acceptable tolerances as specified in the codes and
- Reduce future maintenance cost of the building
- Take care of punching shear i.e use more steel or thickness of concrete where there is chance of punching shear in the concrete slab. To increase shear capacity at the edges of walls and columns embed shear studs or stirrup cages in the slab.
- Check for lateral stability
Methods of Design of Slab
- The finite element analysis
- The simplified method
- The equivalent frame method
