Problem #$2$ Column Design

Given:

$P_D=150$ kips

$P_L=400$ kips

$L=12ft$

$f_C^{\text{'}}=4000$ psi $=4$ksi

$f_y=60000$ psi $=60$ksi

Assumptions:

Use lateral Ties

Assume short$/$intermediate colwmn

Use ${}_g=\mathrm{.}05$

Determine

$(1)$ Column Size

$(2)$ As $($Area of Steel$)$

$(3)$ # is size of rebar

$(4)$ Design size is Spacing of lateral ties
