Problem $8$:

A $350450mm$ column, bent about its strong axis, has $l_u=4m,k=1\mathrm{.}4,P_u=1345kN($the column in question$),P_u=44480kN($all columns in floor$)),P_c=133447kN,M_{1,ns}=95kN-m,M_{2,ns}=100kN-m,$ and $M_{2,s}=110kN-m.$ Material properties are $fc=22$MPa and $fy=420$MPa. Assuming bars are placed along two faces with the centers at $40mm$ from the column face, select reinforcement for the column.
