SEISMIC: Pipe Supports and Thermal Stresses

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have a client asking for help in bracing some large pipes carrying both
superheated and chilled water in an existing building and want to make sure
I do things right.  Can someone steer me to a good reference that might help
with the following questions:

How much inter story drift can a steel pipe riser of given diameter,
supported at floor levels in a high rise subjected to an earthquake, be
expected to tolerate without failure?

To what extent can transverse bracing on intersecting lines or elbows be
relied upon to brace a pipe against longitudinal movement without worrying
about breaking the intersecting pipe and/or elbow joint?

How much do I have to worry about locking in thermal stresses?

Can I safely ignore the effects of hydraulic forces at bends assuming normal
flow rates?

Thanks in advance to anyone who can help steer me in the right direction
