A concrete stairs has 13- 250 mm treads and the risers are 200 mm high. The steps are supported on a 200 mm thick slab, reinforced with 12 mm diameter Grade 40 bars @ 125 mm O.C. If the slab is simply supported and fc' = 21 MPa, what is the max. LL that the stairs can carry based on the Strength Design specifications of 2001?

A simply supported beam is reinforced with 5-ϕ25 mm at the bottom and 2-ϕ20 mm at the top of the beam. Concrete covering to the centroid of reinforcement is 70 mm at the top and 64 mm at the bottom of the beam. The beam has a gross depth of 450 mm and gross width of 300 mm. fc’= 28 MPa, fy = 415 MPa. Assume bars are laid out in a single layer. Calculate the following if the limiting tensile steel strain is 0.004 for a ductile failure: a.
