We a have a quadruple beams 750s diamond approx 12 m span
Drawing shows plans in the top third of the beams
Top of beams have a chord every metre on band and plate & is a boarded lift
You can not thread a tube through the 4 beams as per the drawing .
Because of all the bracing in the beams .
The plan brace tube are 5 fts
As we all know the plans are in the top 1/3 for compression
Any ideas
We thought of the lowest we could put them in is basically the bottom .
But you lose 50% of their strength ( really)
Any one been through this dilemma
