Question
4-1 Figure P4.1 shows a simply supported beam and
the cross section at midspan. The beam supports a
uniform service (unfactored) dead load consisting
of its own weight plus 1.4 kips/ft and a uniform ser-
vice (unfactored) live load of 1.5 kips/ft. The con-
crete strength is 3500 psi, and the yicld strength of
the reinforcement is 60,000 psi. The concrete is
normal-weight concrete. Use load and strength-
reduction factors from ACI Code Sections 9.2 and
9.3. For the midspan section shown in Fig. P4-1b,
compute M, and show that it exceeds Mu-
Wo = 14 kips/it plus weight of beam
