as4100 - rule 5.10.7
found reference to the as4100 rule 5.10.7 (hole size dimensions in beam webs) in an engineering lecture. i have no access to as4100, therefore i am looking for detailed information about rule 5.10.7. thanks gunther
find a job or post a job opening
this clause does not apply to castellated members.
the internal dimension of the opening, lw must satisfy either:
1: lw/d1 must be less than or equal to 0.10 for webs without longitudinal stiffeners.
or
2: lw/d1 must be less than or equal to 0.33 for longitudinally stiffened webs.
provided the longitudinal distance between boundaries of adjacent openings is at least 3 times the greatest internal dimension of the opening.
only one unstiffened opening is permited at any given cross section unless analysis shows that stiffeners are not necessary.
the above is 95% of the text in the standard, the remainder refers to castellated
thank you very much for the fast response. the information received is exactly what i was looking for.
regards fgh
