I am hoping to find someone who is familiar with MDX 2023 - in particular with batch processing. MDX had a major update some time in the recent past, going from MDXv6 to MDX Client 2023. This update involved an upgrade from the 1992-era GUI to a spiffy new 1998-era GUI. Jokes aside, there...
I'm a bridge engineer by profession, but I'm having a bit of an issue at my personal residence at the moment and I'm hoping to get a few questions answered.
We are having carpet replaced on our second floor, and in the process the installers are screwing down the 3/4" t&g ply subfloor to...
I've been assigned as urgent task to compare the AASHTO LRFD luminaire & sign structure spec to the Standard spec 6th ed. version. I'm focusing mostly on fatigue, as that typically controls the design of sign structures. I can also avoid the load factor differences when just comparing the...
I'm not sure if this sort of discussion is allowed, but I am trying to figure out where I fall in the industry for salary for my level of experience and qualifications. Its a taboo topic that many don't feel comfortable discussing for obvious reasons, but it's also critical to career...
I'm working on a bridge load rating in MDX for a bridge in a new DelDOT interchange. DelDOT Bridge Design Manual directs the load rater to perform the analysis for a wide variety of design, legal, and permit trucks as well as various combinations of lane loading. This results in anywhere from...
This post might be better suited in a bridge-specific forum, but it is software related.
I'm working on an LRFR bridge load rating for DelDOT for a newly constructed curved girder bridge. DelDOT bridge design manual requires rating new bridges for a fairly long list of trucks, and the permit...
I am designing a 228ft. simple span bridge, with both abutments at 36° from roadway tangent / girder centerline. Intermediate bracing is colinear per state standards for bridges with this large of a skew. Two-stage construction, with 5 and 7 girder structures for stages 1 and 2, respectively...
I apologize if this is in the wrong section. I did not see a sub-forum related to the PE.
I'm sitting for the PE (civil-structural) in two weeks. I've been running through NCEES official practice exams for preparation. Has anyone noticed the glaring errors in the "official" NCEES practice...
I was wondering if anyone has software verification for the live load auto-gen function in RC-PIER. The office I work in at my firm says they cannot verify the LL auto-gen output, so they have been hand comping LL. Another office of ours still uses the LL auto-gen (don't know if they've...
I'm working on a bridge design that has a noise barrier mounted to one of the parapets. Wind on the noise barrier will produce a considerable load on the fascia girder, so we need to design for it. Due to issues with MDX transferring load through the lateral bracing in girder system analyses...
