    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)

    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

    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

    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

    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

    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

    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...

    Tall Stud Wall / Window Wall Augmentation

    Morning all, I'm looking for a bit of input on a tall wall analysis. We've got a Client that has come asking for help after building a wall beyond the limits of the code AND taller than the plans reflected. They raised the wall 2' and basically crossed their fingers hoping that the inspector...

    Black on Concrete Wall (Photo) What is this?

    A contact on Linkedin just posted this picture. What is going on here? My first thought is mold, but there's no way right? It doesn't really have the correct pattern for that. I see drains so this must be a foundation wall, the weirdest part for me is the texture more than the discoloration...

    Structural Analysis Software for Floating Pontoons/Docks

    Good Morning all, I was wondering if any of you have a recommendation for software to perform structural analysis on floating marina docks (concrete). I've just been mostly using hand calcs to get the loads and running it in RISA (this is the way my boss does it). I've spoken with a few people...

    ASDIP Retain Question

    Afternoon all, I am trying out ASDIP retain, trying to get some sanity checks on my own calculation sheet I'm building for a cantilever retaining wall. But there is one resisting force stated in the ASDIP detailed output that I'm not understanding. It's called "Backfill Pav" and the force acts...

    Primer on Cold-Formed Steel Lateral Systems

    Morning all, I've been trying to read up on how cold-formed steel lateral systems work and I admit I'm a little confused. In some ways it seems like a timber stud wall with light gauge studs instead of timber studs and tracks instead of top and bottom plates and so my mind goes to...

    Structural Engineer Owning a Contracting Business (Ethics)

    I swear I thought there was an ethics sub forum but I can't seem to find it (it's Monday morning [morning]). My question is this: what are the ethical implications of a structural engineer owning a contracting company that goes out and does the work? The work is fairly small scale but for...

    Large Detached Garage Raking

    Greetings all, Finishing up the design of a largish detached garage (64'x30' w/ 14' tall walls, roof peak at 19'). I've gone through the tall wall calcs, designed some 'shear walls', foundations etc. But my boss is concerned that since the long dimension is fairly long there could be raking...

    IRC Wall Bracing End Conditions

    Afternoon all, Quick question on the IRC braced wall provisions. In Fig. R602.10.7 the end conditions for continuous sheathing are laid out. Is CS the only bracing type that requires specific end conditions? For example I have an interior wall with LIB's, do they need any particular end...

    Fix for Cut Truss Web Members

    Morning All, I wanted a second opinion on how to approach repairing some cut roof truss web members. See the attached photos above (I wish I had gotten a few better pictures but you can get the gist), web members of three roof trusses (24" O.C.) were cut to make room for a little alcove in the...

    SET-3G Epoxy and ACI 355.4

    Afternoon all, I have a quick question regarding ACI's anchorage to concrete provisions. My boss has me designing a holdown for a cantilever, it is supposed to be an all-thread bolt drilled and epoxied into concrete. So I go to CH 17 of ACI 318 to get an idea of my capacity and it says that...
