After yes there are glued laminated beams that allow very large range but their cost prohibits use in the particular (or just the very rich a little megalo ...)
the Young's modulus is not the criterion allowing long wear, it is rather the ratio resistance weight ... and in ratio resistance weight the good woods are very good! that's what made it possible to make wooden planes before making them in aluminum
for the construction of home lerapporte resitant weight is not the main one: it is especially the report resistance price, and I find the wood material the most economic as one does not exceed 4 or 5m ... for longer it takes the glued laminated and the glue is too expensive ... I find the glued laminated too expensive, so I confirm that for long worn steel can be more economical
finally do not forget the wood in farmhouse: the farmhouse connectors are cheap and we can assemble wood to make large farms ... alas the farmer builder is made of c ... in gold and try to keep this technique secrete ... yet it's easy and it should be done in self-construction
in France there is a lamentable lack of housing and alas we let the profiteers take advantage of the situation ... there is real politics to do to put the order
