Figure $1$ shows the elevation and main floor plan for a five$-$story building. The floor slabs are $15$ cm thick. Assume an imposed load of $4\mathrm{.}0$ kN$/$ m$2,$ which includes a $1\mathrm{.}0$ kN$/$ m$2$ partition loading. The roof is assumed to have similar$-$sized structural members, carrying a reduced imposed load of $4\mathrm{.}0$ kN$/$ m$2.$ Design the beams along the assigned axis for bending and shear reinforcement, and design the columns assigned.

Calculate for beam axis $2,$ Floor $6,$ Column position: Lower
