Bedding/fixing of feature truss

[cwr]

Hi folks.

The big glulam truss is taking shape nicely in the shed, and will be moved out to its final location in 2 weeks time and lifted into place.

Question is, how best to bed/fix it in? It will be resting on 215mm thick block pier, so thinking about this interface. The structural engineer didn't specify anything, but did give 20kN max vertical load on the kingpost, so there will be 10kN at each end. Builder wondered about some form of steel plate and set on a pad stone. I'm thinking the same, but to what detail?

Thanks

10Kn is nothing (1ton) but I agree you should have a plate to land the truss on. Could be steel or even plastic, couple of layers of DPC etc. Truss bottom cord is plenty wide enough to give a good bearing so really just an isolating layer unless you want to include fixings in which case a steel sole plate would be the best option.

Thanks markc.

Yes bottom chord is 138mm wide so good bearing area. I'll see what steel plate I have about the place, think there's some 6mm I could use.
