This theatre is in a mixed-use building in Sweden

It is 13.5m wide supporting a floor above

The span is too big for a beam

So it has a truss

A hybrid “Pratt truss”

The verticals are glulam

The horizontal top chord is glulam

The horizontal bottom chord and bracing are steel

As timber bracing is not elegant for high tension forces

Maybe an idea for your project ?

Have sketched the key detail for you (right).
