Hi all

Does anyone have any sample calculations or links for timber beams please?
This will be built into wall at each end - supported on internal leaf.
It will take the weight of ceiling and joists only, with whatever imposed
load is applicable for a loft space.
I am particularly interested in the timber grade selection. Not sure what
variety of wood is generally used and therefore allowable stresses etc

You could try:

There are several beam programs here. Don't know enough about it to
comment on how good they are.


Another option is:

You could perhaps do the calcs with the non-printing demo to
see if it does what you want (or screenshots)
