*Design the following*
1.Internal steel truss.: Reaction of each support, nature and magnitude of each member of frame. a) critical truss members. Use equal leg angles for all truss members 45x45x5 ( 3.38kg/m) b) connection onto steel column. Design a bolted and weld options. c) check weld lengths for internal members onto top and bottom chord.
2. Steel beam 5 (use I section -- 457x191x74Kg/m UB) Beam load calculation 3. Steel beam 6 ( use I section 457x191x74Kg/m UB) ---- Beam load calculation 4. Steel column 1 with base plate ( 356x171x51kg/m UB) 5. Steel column 2 with base plate ( use H section 254x 254x89 Universal columns) 6. Connection between Beam 1 and Steel column 1 ( M24 bolts 4.8 class to be used for bolted connection)
The figures and drawings below show the schematic floor plan & section of a laboratory building. The structure is made up of steel trusses, supported onto steel columns onto reinforced concrete pad foundations. The roof is clad with corrugated steel sheeting with a weight of 10 kg/m. The building is enclosed with 220mm brickwork around the perimeter. The laboratory requires the truss to support a load of 200kg at mid-span. The first floor is a 200mm 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 2200 kg/m. The soffit of the slab has a 25mm plastered finish of 2300 kg/m'. Make reasonable assumptions for any information not given. (Neglect wind loading & structure stability, i.e.bracing.) All steel is to be grade S355JR and all connections to be of ordinary bolts class 4.8 and welds to be 6mm (E70XX).
