Constructing Environmentally Friendly Large Timber Trusses
If you can
locate a source of recycled timber you can go ahead and use it for truss design
in the normal way, but these days this opportunity is rare.
Last time I
was looked at this problem was when John Barnes from Woods Bagot wanted
relatively shallow scissor trusses to span over 25 m for the Jindabyne Visitors
Centre.
I looked at
a number of options including LVL and Glulam but found the cheapest attractive
solution was to mechanically laminate 4 250*50 lengths of plantation hoop pine
to form the truss chords.
Using the
same technique for the columns we were able to design an elegant connection
detail with all flush faces. This is
certainly not the only way to save the environment but the building did win a
number of design awards.
If you
