The T-beam shown in Figure 1 supports the un-factored dead load
of 1.4 kips/ft and live load of 1.5 kips/ft. The dead load does not
include the self-weight of the beam. The material properties are as
follows: fc’=3000 psi; fy=60,000 psi. Design the shear
reinforcement (stirrups). Plot the stirrups distribution along the
span of the beam.

kips/ft and a calculated dead load of 1.05 kips/ft on an 18 ft
simple span is limited in cross section for architectural reasons
to 10 in. width and 20 in. total depth. If fy=60,000 psi and
fc′=4,000 psi, what steel area(s) must be provided.

Design a rectangular simple supported beam to carry service loads of 1.05 kips/ft of dead load (DL) (self-weight included) and 2.47kip/ft live load (LL) on a span length of 18 ft. The beam is limited to be (due to architectural reasons) 10” wide with an overall depth of 20”. Use f’c= 3,000 psi and fy= 40,000psi. Design the longitudinal reinforcement (flexure design) and the web reinforcement (Stirrups).

A rectangular beam having b=16 in and d=26 in spans 28 ft face
to face of simple supports. It is reinforced for flexure with 6#11
bars that continue uninterrupted to the ends of the span. It is to
carry service dead load 2.0 kips/ft (including self weight) and
service live load 3.6 kips/ft, both uniformly distributed along the
span. Design the shear reinforcement using vertical U stirrups.
Economize the spacing of stirrups in appropriate number of bands.

Determine if the beam shown in the figure is adequate as
governed by the ACI
Code (318-11). The loads shown are service loads. The uniformly
distributed load is DL =
0.65 + 0.F = _________ kip/ft, LL = 0.55 + 0.E = ________
kip/ft. The dead load excludes
the beam weight. The point load is a live load. f’c = 3,000 psi,
fy = 40,000 psi.

A rectangular beam having b-10 in. and d= 17.5 in. spans 15 ft face to face of simple supports. It is reinforced for flexure with three No. 9 (No. 29) bars that continue uninterrupted to the ends of the span. It is to carry service dead load D 1.27 kips/ft (including self-weight) and service live load L -3.70 kips/ft, both uniformly distributed along the span. Design the shear reinforcement, using No. 3 (No. 10) vertical U stirrups. The more approximate...

1. A rectangular beam with b 16 in., d-17 in., and h 20 in. has a clear span of 24 ft. as shown below. The beam has 1 ft. of bearing at each end, so for analysis purposes it is treated as a 25 ft. simple span (to center of bearing at each end). The beam supports an unfactored concentrated live load of P-65 kips. The beam is reinforced with 6-#10 longitudinal bars and #4 stirrups. Material strengths are fc-4,000,...
