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?
Some of the best education and growing as an engineer have...
bridgsmith, excellent suggestion, but we're locked in that direction with the anchor bolts. Slots in the sole plate are the opposite direction of intended sliding.
Perm bearings are elastomeric. The main focus is to get the girders back centered on the sole plates, the bridge is still under construction and there isnt a deck. The jacks we will be using will be a bit squirrly to slide on top of them, which is why were looking to lower it back down on the...
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...
GC - Our QC is good, I am confident the welders are producing good welds, and following procedures.
dhengr - I get that it is a silly statement. Just kinda wanted to direct focus to the point. I have attached a very poor sketch for everyone's entertainment. Failure on the really bad ones are...
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 ran into this problem not to long ago. Sadly see this excerpt... From AASHTO LRFD 2014: "AASHTO LRFD Bridge Construction Specifications places the responsibility on the Contractor to provide adequate devices and methods for the safe storage, handling, erection, and temporary bracing of precast...
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...
Hilman said Aluminum isn't acceptable, no other reason.
I have to man handle all these pieces, I wanted aluminum to save weight. S/S is out because its heavier then C/S.
I have Roark, never used it, think table 14.1.2 is the right spot? I am still unsure if I can do the equation with any...
