European Beech Strength Class 1

[hemis]

Does any one know the European Strength Class for European Beech: I need to know the shear parallel to the grain and compression perpendicular to the grain? I am using BS5268 but I could use EC5.

Many thanks

From the publications I have to hand, the only data I can find is for German sourced European Beech which puts it in D35-D40 strength classes (ref. BE EN 1912:2004).
According to BS EN 338:2003, compression perpendicular to the grain can be calculated as 0.015 x Characteristic Density (560-590kg/cu.m) for hardwoods. I believe the characteristic shear strength specified (fv.k) is applicable to both perpendicular and parallel directions. This is also indicated in EC5 cl.6.1.7.

Hope this helps...

According to these values for the spanish Haya a D70 class seems acceptable and then 13.5 MPa compression normal to fibre and 5 MPa shear strengthd (by Spain's CTE code Table E.2).

Thanks for the response

D35 sounds good to me and thanks Trevor for the EC5 clause. I am dropping BS5268 after my current project as I am finding EC5 a better standard. I am also finding advantages with the EC2 over BS8110 - not that I am an expert with concrete.
