ASSIGNMENT:

The figures and drawings below show the floor plan & section of a laboratory structure. The structure comprises steel beams and columns supporting a reinforced concrete slab, all supported onto reinforced concrete pad foundations. The building is enclosed with $220mm$ brick walls on all $4$ sides and a timber roof $(30\frac{kg}{m^2}).$

The first floor is a $250mm$ reinforced concrete floor supported on steel beams that span between columns as indicated. The steel beams have shear studs cast into the slab $($the purpose of the shear studs is for lateral stability and not composite design$).$ The floor has a finish of $30mm$ screed of weight $2200k\frac{g}{m^3}.$ The soffit of the slab has a $25mm$ plastered finish of $2300k\frac{g}{m^3}.$

A frame $(C13,C14,$&$B17)$ on the first floor should be capable of carrying a load of $1000kg$ at midspan.

Make reasonable assumptions for any information not given. $($Ignore wind loading & structure stability, i$.$e$.$bracing.$)$

All steel is to be grade S$355$JR and all connections to be of ordinary bolts class $4\mathrm{.}8$ and welds to be $6mm($E$70$XX$).$

Provide a brief report explaining the steps you took to plan your design process and any assumptions made.

Design the following:

Steel Beam B$17.$ Use an I section with pinned supports at the columns.

Steel Column C$05.$

Bolted connection of $B04$ onto the flange of colC$05.$

Beam B$16.$

Base plate for column C$05.$
