You are given a $24$ inch square concrete column with longitudinal steel bars $($As$)$ equal to $8-$

#$14$ bars and #$4$ bars used as lateral ties. The column will have an exterior exposure.

Concrete strength $=5,000$ psi, steel strength $=60$ksi.

How many more #$14$ bars can you distribute around the perimeter of the cross$-$section while

staying within the limits of the design code AND keeping the column's moment capacity

balanced?

$0$

$4$

$8$

$12$

Question

A $16$ inch $22$ inch concrete beam is reinforced with $4$ #$10$ bars in the tension zone.

Calculate the Concrete Shear Contribution of the beam, Vc

Assumptions: $$

$d=h-3$; Exterior Exposure; Shear tie $=$#$3$;$f^{\text{'}}c=4$ksi;$Fy=60$ksi; unit weight $=150l\frac{b}{f}{t}^3$

$34\mathrm{.}4$ kips

$38,453lbs$

$19\mathrm{.}2$ kips

None of the above
