Solve the following using EC$2$ The figure shows a frame of heavily loaded industrial structure which only the centre column of the first floor under side along line pQ are to be designed for The frames at $4$m crntres are braced aginst

lateral forces and support the following floor loads:

Permanent action, $g_k=13k\frac{N}{m^2}$

Variable action, $q_k=17k\frac{N}{m^2}$

Characteristic materials strength are

$f_{ck}=25\frac{N}{m}{m}^2$ and $f_{yk}=500\frac{N}{m}{m}^2$
