Problem 3 Check the adequacy of the double reinforced T-beam in the middle as shown below. Clear spacing between the bar layers is 1.0 in. Concrete clear cover is 1.5 in., and eight No. 9 bars are used. Span length is 30ft. Use fc=3500psi and fy=60,000psi. The floor carries a live load of 100psf and a non-structural dead load of 50psf. Consider own weight of beams and slab. Problem 3 Check the adequacy of the double reinforced T-beam in the middle as shown below. Clear spacing between the bar layers is 1.0 in.
