To break it down analytically, I have looked at the pipe properties as follows:
S = 15.8 in3
E = 24,000,000 psi
self wt = 30lb.ft
weight of water = 22lb.ft
Allowable stress = 48000psi per DIPRA
I submit that we can consider that the 8'-0" span with a joint in the middle conservatively as 2...
Brillant. I designed a complex foundation to span over this and it never occurred to me to move the pipe.
This is a critical utility and shutdown of the pipe would cost more time and money than a redesign of the foundation. This is a less than optimal solution for everyone involved, but the...
Does anyone have any pointers on how to identify the maximum support distance from a joint/fitting for a span of ductile iron pipe? The pipe in question is 8" diameter and carries water. Looking through the Ductile Iron Pipe Research Association literature and webpage, the closest information I...
From IBC 2003 - 1617.5.3:
"Diaphragms constructed of untopped steel decking or wood structural panels or similar light framed construction are permitted to be considered as flexible."
In IBC 2006, see 1613.6.1
