My questions are probably simple for some, but would like to seek some clarity as to the actual number values I am dealing with and which should be allocated to the expressions outlined below:

For the value of "ti timber or board thickness or penetration depth, i = (1, 2)." is this just the timber thickness, i.e, 44mm?

What does this ask for:"fh,i,k = characteristic embedment strength in wood member i."

And the therefore the value of "β"

For the "ratio between embedment strengths of members." I am assuming that I need a value for individual timber section thicknesses, more so if they are different, i.e, 44mm and 38mm, but on the basis they are C24, I cant see how the number will be different.

Values for C24:

I was going to use a value for a 4.6, 12mm bolt to apply to the equation, & the basis my 2 timbers are 44 x 195 C24

Hope this makes some sense TIA.
