    SE Exam October 2023

    I still remember the dread of opening up the emails with my results in them. So glad I did it though. Really curious how the new computer-based version will go. Ian Riley, PE, SE Professional Engineer (ME, NH, VT, MA, CO, FL) Structural Engineer (IL, HI)

    Slide Rule Era

    I'm Giving Away Structural Engineering for Free - Visit Your Wrath Upon Me

    I mean, maybe this is the way to go? Offer free labor and apply your engineering to help out with the job? Someone wants a porch built, help build the porch and give them advice on how to attach the ledger, flashing, which screws to use, member sizes, etc. Good exercise too. Ian Riley, PE, SE...

    I'm Giving Away Structural Engineering for Free - Visit Your Wrath Upon Me

    My vote is don't do it for free (or cheap) but do it in a way that helps out most. I guess I'll use an example. I volunteer my time for a local flying club and help them as treasurer, keep member records, help manage the airplanes, etc. I got my flight instructors rating not to make money or...

    Structural Engineering Fees - is it broken?

    I do a lot of delegated design work for fabricators and contractors and I've found that they are willing to pay good percentages of the total cost precisely because of what KootK said; my work is almost always peer reviewed by the EOR or a sub-consultant of the EOR, and the fabricator/contractor...

    RISA 3d v 18 - New format

    I'm busy tonight so I'll need to revisit this; I want to collect my thoughts more anyway and experiment with more things. Short version is I'm not impressed; some UI quality of life changes are appreciated but the overall usability of the program has decreased overall. Creating a simple 2D...

    Liability Insurance

    Oh it totally is; if you want to, your client pays for the cost difference, and your insurance provider will let you, then my understanding is that this is a benefit to you. However, if they do have design professionals on staff then it's definitely NOT in your interest as you'll likely share...

    Liability Insurance

    I just send them this link: http://www.cavignac.com/publications/professional-liability-update-why-your-clients-dont-want-to-be-an-insured-on-your-professional-liability-policy/ Basically they shouldn't want to be an additional insured unless they're also involved in the design work as a...

    Cybertrucks and Bumpstocks and 3D printed guns

    I can make something resistant to 9mm easily with a few layers of plywood. 9mm is not a high-penetration round which makes it great for self-defense (no over penetration), target shooting (low recoil), and general practice (lower cost ammo). 7.62x39 ammo in my SKS will penetrate small trees and...

    Contracts for work under 1k

    Maybe not the best advice but I took some old short form contracts I had from other past employers, the ASCE short-form contract, and some general internet legal advice and made a 1-page terms and conditions of what I consider the most critical contract items attached to a simple cover letter...

    CIP Box Culvert Construction Joints

    I don't see anything wrong with it either. As Joel said, roughen and shear friction or a shear key joint. You'll have less clamping force than the joints on the walls but should be more than sufficient to always provide clamping across the joint. The shear there will be highest due to vehicle...

    PCI certification versus NPCA certification

    PCI is much more involved than NPCA certification. Back when I worked for a precaster the two plants I was involved in the one that did prestressing operations had PCI certification as it's practically required if you're doing prestressing jobs. The other plant did not do prestressing and found...

    Dual Wood Post Bearing - Differential Bearing Issue

    I'm going to go with not a problem. If you get any differential shrinkage (which I don't expect to be a problem as the difference should be minor) the bearing of the beam on the post should compress more on the un-shrunk side until you get roughly equal load transferred to the posts. In...

    Monorail Impact/Dynamic Factors for Existing Crane

    I'm not confident but based on my experience they used similar vertical and horizontal impact factors to the ASCE 7 ones we use today. Again, that's based on experience but I've never actually hunted down the codes from that era to check so I may be wrong. Ian Riley, PE, SE Professional...

    ACI Prestressed flexural member deflection

    Sounds like the author is just making a recommendation that you keep tensile stresses below 6SQRT(f'c) to avoid cracked section calculations. Antoine Naaman has a similar recommendation in his book: His rational for 6SQRT(f'c) instead of the 7.5SQRT(f'c) now in the ACI code is that testing has...

    Slab horizontal bars

    Put me in the diagonal camp as well. It's the mandatory walking style when the bars are spaced wider than your foot. Ian Riley, PE, SE Professional Engineer (ME, NH, VT, CT, MA, FL, CO) Structural Engineer (IL, HI)

    Are minimum reinforcements additive?

    Celt, ACI 318-14 has 9.5.4.3 which is the same: "Longitudinal and transverse reinforcement required for torsion shall be added to that required for the V u , M u , and P u that act in combination with the torsion." Ian Riley, PE, SE Professional Engineer (ME, NH, VT, CT, MA, FL, CO)...
