CVEN 444 Assignment 14 due 7/18/03
The assignment will be review problems and will not be covered in
class. Use an engineering format and be neat!
1. Determine the length of the top and bottom bars for the external
span of the continuous beam. The concrete is normal weight
and the bars are Grade 60. The total uniformly distributed
“factored” gravity load on the beam is wu = 6.5 k/ft (including
self-weight). The beam has an fc = 4 ksi, fy = 60 ksi, b= 14-in.,
h= 28-in. and concrete cover=1.5-in.
a. Determine the singly reinforce beam needed for external
beams for both the positive and negative moments.
b. Draw the shear and bending moment diagrams for the
beam and determine the amount of steel need for
bending. Use the ACI code to find your moments. Hint:
There are more than one set of bending moment
diagrams.
