Hi Mark,

You can check out a link to Hume & Son Engineering where you can download a composite stress *.pdf file that shows typical deflections on a simple queen post truss frame, axial stress diagram for a hammer beam roof, shear stress diagram for a typical big American barn frame and bending moment diagream for a lattice truss frame.

I have toyed with the idea of producing either an article or short book on the recording and analysis of historic timber framed structures but have wondered just how many people would actually be interested in this type of thing.

I will be recording a lovely 3 bay Wealden town house in Farnham at the beginning of May specifically to produce a 3D CAD model of same. It might be appropriate to follow this project through and publish the actual timber sizes employed together with typical stress, moment and deflections predicted by present day structural analysis for this 600 year old building. It is a particularly good example of a solidly built and fairly complete survival of this important traditional frame type.

Regards
