...a mechanical engineer.
I did some structural design for a buried concrete tank and thrust block a year or so ago. Subsequently, I was asked to size tension rods, bolts, and plates for a restrained ductile iron pipe joint, which was to be housed in the buried concrete tank. This DIP is very large (60" dia.), and the restrained flange connection was going to see working forces of 33 kips per tension rod (a set of 8 rods).
It was a rush to get this checked (like always). My immediate thoughts were: Where is the mechanical engineer? and, ah...fatigue!
Should I be protesting this type of design as an EIT? Or, should I start reading the ASME design manuals and prepare for this sort of request in the future (we recently started doing a lot of the structural work for the buried buildings housing this mechanical gobbledygook?
In Russia building design you!
