Question $1(35$ marks$)$

Figure $1$ shows the arrangement of floor beams and column supports $($all dimensions in mm$).$

The beams support a $200mm$ thick concrete $s1ab(2400\frac{kg}{m^3})$ with a $50mm$ screed $($cement & sand plaster$).$

All beams have a self$-$weight of $80k\frac{g}{m}.$

Determine the following:

a$.$ Design load of Beam $6$ at ultimate limit state $($ULS$).$

Draw a sketch of the beam indicating the load arrangements.

$(6)$

b$.$ Calculate the reactions for Beam $6$ at ULS.

$(4)$

c$.$ Determine the design moment for Beam $6.$

Question $2(40$ marks$)$

The beam shown in Fig $2$ is laterally and torsionally restrained at the ends only and is required to carry the following loads $(W)$:

Permanent $($dead$)$ load: $,5k\frac{N}{m}($including self$-$weight$)$ Imposed Load: $,15k\frac{N}{m}$

Check the suitability of the section using Grade S$355$JR steel.

Check flexure, shear & deflection $($use normal loading conditions$).$
