A 5 in thick simply supported
reinforced concrete one-way slab is part of a roof system. It is
supported by two masonry block walls, as shown below. Assume a
superimposed dead load (roofing, insulation, ceiling, etc.) of 15
psf and a roof live load of 30 psf. Check the adequacy of the slab,
including the required shrinkage and temperature reinforcement. Use
