Default Span Length

When entering the span length in Superbeam should it be the clear span or the span between bearing centres? I have two load bearing walls 6m apart which I wish to span for a loft conversion. The beam will be placed on 100 mm wide bearing plates or pad stones so the distance between bearing centres will be 6.1m. Should I use 6m or 6.1m for my bean calculations?

Default Re: Span Length

The span should be taken as the distance between centres of bearings, save that if the bearing length is longer than strictly necessary you can take the span as being the distance between the centres of the required bearing lengths.
