Q3. Now consider the studs within the walls that support the mezzanine floor. To do this, undertake calculations to check whether 100mm x 50mm rectangular section (90mm x 45mm dried size) timber sections would be able to sustain a ULS compression load due to 1.2G+1.5Q of N*= 21kN. Assume that the timber is SG8 and that member buckling is not an issue (i.e. just do the section checks as per Chapter 2 of reader). Report the ratio of demand to capacity; N*/ϕN_nc,timber. [%]
