The floor beam shown is on a simple span of 16 ft. The beam supports nonstructural elements likely to be damaged by large deflections. The service loads are 0.6 kip/ft dead load (does not include the beam weight) and 1.40 kips/ft live load. Assume that the live load is 60% sustained for 6-month periods. Use f′ c = 3000 psi and fy = 60,000 psi.
a. Check the beam for deflections.
b. If the beam is unsatisfactory, redesign it so that it meets both flexural strength and deflections requirements.
