I consider myself fairly versed in BTH-1 and B30, but would like to attend a course/seminar from a guru on the topic. Im thinking a week long, classroom style, page turn of the spec with worked out examples. Anyone know if this exists?

I need help with a temporary fix. I need to design a sliding bearing to shift a bridge a few inches (like 2in max). 5 girders max vertical reaction at each girder will be about 50 kips. My plan is to jack the bridge up using hydraulic rams, place a PTFE sheet sandwich between the bottom flange...
I am searching for a steel alloy recommendation to make a shop made tool that is basically a longer and larger diameter nail set tool, nail set like you would use in carpentry to countersink a nail. I am searching for, hopefully, a non exotic alloy that can be purchased easily in round bar...
Without getting into the weeds to much with specifics, my company does pretty specialized pile driving and we use shop made adapters to drive varying pile sizes, larger and variable shapes that need an adapter for the hammer. The adapters are usually weldments of some shape using usually carbon...
I plan to be giving a brief talk during an AWS - Welders Night Out about topics we engineers think about when designing welds. Not calculations but some "whys and other things related". If you all wouldn't mind letting me know from your experiences what are some things you would or possibly...
I have an application were it would be beneficial to use an aluminum (6061-t6) channel or plate (has to be manhandled) to use as my rolling surface for a loaded hilman roller. I am using a Hilman roller model 20-OT that has 5 contact rollers that are 4" long X 1.18" OD. My load is 39.5 kips per...
My schooling as a CE didn't really teach me much in the realm fatigue in weldments and connection design. But now in my career I am attempting to do this design work and am needing resources to teach myself how to do this. If anyone has any "fatigue design for dummies" resources that helped you...
I am demoing an old reinforced concrete 10 inches thick, we will be saw cutting the deck into pieces ranging from 15' to 20' long x 4' wide (about 8,500 to 11,000 lbs). I am looking for unique suggestions on how to attach my rigging to the cut pieces. I will have no access to the bottom side so...
First please forgive me, if this is the wrong forum for this question I will remove it asap. Second please forgive me as I have no experience with plastics.
My question is based upon my attached sketch. The sketch is a plan view and elevation view of a precast concrete pile (36" diam) and the...
(Sorry mods for posting this question in the "other topics" board too, perhaps this board is more suitable.)
Ill preface this by saying this is very rough number and my schooling is failing me...
I am trying to find the equivalent moment on the columns of a simple structure. See my attached...
Hi all,
I am looking for a connection device that does not require drilling or welding. This drawing is the connection detail. It is a W12x65 flange to a W12x65 flange and the beams are perpendicular.
I have in mind some kind of clamping system preferably something that is a quick disconnect...
I am trying to convince myself that I am using a formula from the AISC manual correctly.
The project is to design a large counterweight for a device, and I am designing it as a steel plate box welded together and filled with concrete.
Here is the problem:
I want to design the counterweight...
When cutting A36 plate on a plasma table, is there a preferred way to cut a long slender piece. Lets say the starting plate is a standard 8' x 40' x 1/2" thk and I need 10 ea. 7'-0" x 4" strong backs cut. Ignoring plate utilization, what would be my best way to nest these pieces... will the...
Hello All,
So sort of new to WPS and prequalification of procedures, however I am required to have one for welding round bar to piles. This is something that we have done for years but have never been required to have a procedure for... well at least not to my knowledge.
Here is the detail...

I am building a sign truss structure with 3 1/2" OD truss diagonals that will meet up with a 4 1/2" chord. My issue is there is a LOT of diagonals and to hand cut all these copes by hand will take many many hours, so I am looking for a machine to do this for me.
I have...
