Question 6

Equation for net area of plates with holes

Answer 6

An = tp ( Wp - ndh + ms^2/(4g))

n = number of holes in failure plane
m = number of gage spaces
dh = nominal bolt hole diameter + (1/8 or 1/16)

Equation for net area for structural shapes with holes

Answer 7

An = Ag - tp (ndh + ms^2/(4g))

n = number of holes in failure plane
m = number of gage spaces
dh = nominal bolt hole diameter + (1/8 or 1/16)

Don’t forget U factor where applicable!
