Normally if columns of the steel structure are braced i dont think you really need a Tie beam.Tie beam could be a compressive or tensile member it really depends.
if I were you and I would design a steel structure say 1 floor building and I wouldnt bother to provide tie beam...
For simply supported beam I have used 4 dia 10mm bar as a hanger bar at the top for a beam of 500 deep and 400mm wide.I havent seen any restriction using dia 10m bar in British code.
my beam size is 300mm(12in) wide by 500mm(20in) deep.I have used 4 No. dia 10mm at and 4 No dia 20mm at the bottom for simply supported beam.I have added two extra dia 20(Top) at support in case of continuous beam.These bar is enough for bending and also it covers the minimum reinforcement...
Can we use dia 10mm bar in the beam as a top and bottom reinforcement as per British Standard.My problem is I can only use either dia 10mm or dia 20mm for longitudinal reinforcement for continuous beam due to availability of reinforcement on site.Code is specific for column not to be used dia 10...
