Slenderness Ratio ~ this is the relationship of the effective height
to the effective thickness thus:-
Slenderness ratio¼effective thicknesseffective height ¼ht > 27 see BS 5628jEffective Height ~ this is the dimension taken to calculate the
slenderness ratio as opposed to the actual height.
Typical Examples † actual height = H effective height = h
Effective Thickness ~ this is the dimension taken to calculate the
slenderness ratio as opposed to the actual thickness.
Typical Examples † actual thickness = T effective thickness = t
Stress Reduction ~ the permissible stress for a wall is based on
the basic stress multiplied by a reduction factor related to the
slenderness factor and the eccentricity of the load:-
