HELP PLEASE!!!

Please make all calculations

Step $1$ Organize an earthquake resistant steel structural system in fifth floor on $RC$ structure is essential, steel structure should include both two$-$way and one$-$way systems individually, i$.$e two of three parts will be two$-$way and one$-$way steel structure $($smaller parts are suitable$).$

Step $2.$ For beams, take the bending moment q L$^2/5$ in one$-$way and main beams in two$-$way, calculate beam size. For truss, joint loads from purlins are considered.

Step $3.$ Determine column type and sizes $($take Le$=1\mathrm{.}5$L$).$

Step $4.$ Decide beam type $($cellular or truss beam can be used as well$)$ Floor height$=4$m

For one$-$way system $($function: atelier of faculty$),$

Remove inner columns, and organize one$-$way steel structure

Decide to cladding type, load and then purlin spacings $($snow load can be omitted$)$

Organize lateral stability $($purlins$,$ bracing, sag rods$)$

For two$-$way system $($function: classes, offices of faculty$)$

RC Core continues to this floor.

Composite floor can be $10cm$ in$-$depth.

Choose secondary beams in long direction as much as possible.

Secondary beams in long direction can be cellular or truss beam as pinned

connection.

Dead load $=3\mathrm{.}1$ kN$/$m$^2$

Live load$=2$ kN$/$m$^2$

Place columns and beams and determine their apropriate sizes for the plan
