Instructional Objectives:
At the end of this lesson, the student should be able to:
  • determine the shear force of two-way slabs subjected to uniformly distributed loads, 
  • state the two types of two-way slabs mentioning the differences between them, 
  • determine the preliminary depth of two-way slabs of different support conditions from the span to effective depth ratios as given in IS 456, 
  • explain the provisions of torsion reinforcing bars at two types of corners of a restrained two-way slab, 
  • design the two types of two-way slabs applying the different methods explained in this lesson and draw the detailing of reinforcing bars.
Two-way slabs subjected mostly to uniformly distributed loads resist them primarily by bending about both the axis. However, as in the one-way slab, the depth of the two-way slabs should also be checked for the shear stresses to avoid any reinforcement for shear. Moreover, these slabs should have sufficient depth for the control deflection. Thus, strength and deflection are the requirements of design of two-way slabs.
