Design of Short Columns Subject to Axial Load and Bending - Design of Reinforced Concrete - page 314

c In Problems 10.22 and 10.23 select reinforcing for the short columns shown if f y 60,000 psi and f 4000 psi. Check

results with the Bresler equation.
Problem 10.22

Problem 10.23 ( One ans. 8 #9 bars)

For Problems 10.24 to 10.26 use the enclosed CD-ROM.
10.24 If the column of Problem 10.8 is supporting a load
P u 250 k, how large can M ux be?

10.26 If the column of Problem 10.14 is to support an
axial load P u 400 k, how many #10 bars must be used
to resist a design moment M ux 180 ft-k?

10.25 If the column of Problem 10.13 is supporting a
load P u 300 k, how large can M ux be if six #9 bars are
used? ( Ans. 260 ft-k)

10.27 Prepare a flowchart for the preparation of an inter-
action curve for axial compression loads and bending for
a short rectangular tied column.
