What is a relieving arch

[WeWillFigureItOut]

Hello everyone,

I was perusing the 2012 IPC this morning and came to section 305.3 "Pipes through foundation walls" when I found the term "relieving arch" mentioned. For the past hour I've been searching google for a technical definition of a relieving arch and I haven't found anything that satisfied my curiosity. Would a the structural engineer of record define what a "relieving arch" is or are there some accepted parameters for this?

Thanks in advance for any help.

Welcome


I have seen the requirement for underground fire sprinkler pipe going through a foundation

Will have to see how it reads

I think it is there so if the foundation shifts, it does not damage the pipe

A sleeve 2 sizes larger and if your on the cheap, cut it in half forming a pipe arch.

Don't know why the code just sez (Sleeve 2 sizes >)
