    Historic Brick Proof Loads

    Afternoon all, I am working on a renovation of an existing historic brick building. It's over 100 years old and I'm just not sure how to approach the brick condition/ verifying that the brick can handle the additional loads. The extent of the renovation as far is the brick is concerned are...

    ETABS PT Beam Modeling

    Good Morning all, I am working in ETABS on a new building design that involves some PT transfer beams. Beams have been designed separately but I'm including them in our gravity ETABS model to take into account the PT effect on deflection. This is the first time I've ever used PT in ETABS (or...

    Analysis of Irregular Shaped Structures (Diaphragms)

    Yeah, should have mentioned that NEHRP was my first stop, but so much of it was focused on seismic and this building is in SDC A.

    Analysis of Irregular Shaped Structures (Diaphragms)

    Good Afternoon all, I'm working on an analysis of a concrete diaphragm with multiple large openings. I'll admit that as a junior engineer my knowledge of diaphragms is pretty much limited to the simple examples required to pass the PE. I've leafed through Malone and Rice's "Analysis of...

    Identifying Historic Metal Deck (1960's)

    Good Morning all, We're working on a renovation of a historical building and I'm trying to identify the metal deck they used in the composite floor system. There was already a renovation done around the 1960's and we believe this floor was installed for infill around that time. The total slab...

    Virginia (and everywhere else) SE License Discussion

    Ideem I didn't realize you needed more than a BS to take the exam, that's a little weird... WARose yeah. I've seen those stats, those lateral pass rates are rough...

    Virginia (and everywhere else) SE License Discussion

    phamENG yep, I took a course for the PE as well, it was extremely helpful. And yeah, I didn't really mean that the SE was causing burnout, just that it's an extra thing on top of it. sticksandtriangles I think that makes sense, except that so much of what I'm learning is software, it's not...

    Virginia (and everywhere else) SE License Discussion

    phamENG Lol, that would be quite the hurricane, let's hope that doesn't happen. But yeah I hear what you're saying, first of all I do indeed work for one of those firms in DC, and I hadn't thought of how useful it would be working with the other offices, that's a fair point. I think the mobility...

    Virginia (and everywhere else) SE License Discussion

    Just kind of a general inquiry here. I'm trying to get people's thoughts on taking the SE exam. Very typical post I know, but I have a couple specific things I'm curious about. I just took and passed the PE and I'm in no rush to get back to studying. But I feel like I use so much software at...

    ETABS O/S #52

    @Rich242 Umm, yes and no (mostly no) basically, I asked my supervisor about it and he said he had a way to fix it, and working it out is on a long list of things to do before the next submission. But I basically think it goes back to the bracing conditions/slenderness issue. But I'll let you...

    ETABS O/S #52

    @EZBuilding Yep... Just realized the O/S explanation was on Pg 2 of the details... Looks like a slenderness issue I guess.

    ETABS O/S #52

    Good Afternoon all, Have any of you run into O/S #52 in the ETABS concrete design module? I've got a handful of columns that are coming back overstressed but it doesn't quite make sense based on the loading and the height. I.e. only a few are failing but there are a bunch of other columns just...

    Etabs Freezing Issue

    Morning all, I'm working in Etabs for the first time and I was wondering if anyone else has run into an issue where creating a new model freezes your computer, I can't even create a grid system or a blank model without it completely freezing everything. I've tried this with both v18 and v19 to...

    Approach to Historical Steel Shape Analysis

    Gotcha, Thanks strucSU10 and phamENG I'll ask my PM how we came to the 30 ksi conclusion, it looks like the timeline is fairly long so I imagine that testing either has been done or will be done to confirm that. strucSU10 Yeah, the connections are definitely going to be a little weird, on top...

    Approach to Historical Steel Shape Analysis

    Afternoon all, So I wanted to get your opinions on using the 1st edition of the AISC manual. We have a historical building that we need to analyze, I've been told that the yield strength for the steel is 30 ksi, also, I see on the general notes that the steel is ASTM A7-58T (can't find the...

    SAP2000: Model Ill-Conditioned due to temperature load

    Hey all! I really appreciate your help, after looking at your advice and playing with the model a bit more it appears that I was mistaken. The ill-conditioned error wasn't due to the temperature load. I wasn't able to get it to work properly yesterday so I did some hand calcs to get a quick...

    SAP2000: Model Ill-Conditioned due to temperature load

    Good Morning all, I was hoping to get a bit of input/de-bugging on a sap model I'm working on. It's one of a few pedestrian bridges I'm working on for a park. Very simple, HSS stringers, metal grate decking, slight elevation change between the left and right abutment. My issue is that when I...

    Firetruck Loading over SWM Vault

    Morning all, I am following up on this thread, I've gone through the design of this SWM vault and everything looked good and it was checked. But something has occurred to me. The controlling case of this design for moment up until this point has been a specific firetruck outrigger loading...

    Firetruck Loading over SWM Vault

    Afternoon all, I am working on the design of a stormwater management vault and I was wondering how exactly to approach firetruck loading specifically with respect to the lid slab. I know there have been some older posts on this but I'm still a little unsure. Soil depths over the slab range...
