    Structural Engineering Detail Library

    @3DDave This is exactly what I was looking for. I didn't know how to create a website to hold all my details so I could easily search for them. How does one go about creating a Wiki? Is it just written in HTML? Thanks to everyone else who replied. This is turning into an interesting thread to...

    Post Tension Slab Design Software

    ADAPT Building might be overkill if you're using RAM as well. ADAPT PT will be most useful. We did a concrete parking structure and ordered ADAPT Building and would've been better off with the cheaper ADAPT PT, because that's all we really needed since we used RAM Structural for lateral. If...

    Structural Engineering Detail Library

    @thaidavid we do the same thing with the subfolders, but don't keep a spreadsheet. I think the system i created for searching the library using key words will help since our library is getting bigger as we diversify our projects. I'm interested in hearing from anyone in a big firm, how they...

    Structural Engineering Detail Library

    @Rabbit12 There a certain details that I remember being on other projects I've done and will go back and "rob" those details as well...except they were mine, so it would be more like "recycling". I actually just experimented with creating jpeg file out of the CAD details then assigned tags to...

    Structural Engineering Detail Library

    Wanted to get some input on the different ways of managing a detail library. The firm I am at has built up a library full of typical details you can pick out and customize for each project. They are all printed out on paper and appear as a book, if you will, of details separated into different...

    "Puddle" Concrete Construction

    Anyone know what "puddling" is in concrete construction. It was a term used in a webinar today in the context of high strength concrete columns. It seems to be a way of continuing the strength of the concrete column through a slab. Thanks in advance.

    New Rooftop Solar Panels

    Thanks, everyone. I already checked seismic which was easy. The rafter tributary is interesting; I asked for cut sheets on the panels, so I haven't checked it yet. But it's a commercial building so I doubt the 2x4@24"o.c. will work. @WARose: I have the same thing, but it's tilt-up so adding...

    New Rooftop Solar Panels

    KootK: Thanks. Nope, no snow. And the solar panels are low so there is no room for crawl space. Thanks, again.

    New Rooftop Solar Panels

    I wanted to check my thought process on adding solar panels. The code allows a 5% change in gravity loads to avoid retrofitting the structural elements. The solar panels are fairly light and if you really think about it, wherever you place the solar panels, you're removing the area for roof live...

    Existing Cantilevered Column System for a Two Story?

    KootK: Thanks. Just wanted a second opinion. Thank you.

    Existing Cantilevered Column System for a Two Story?

    I am doing a remodel for a two-story commercial building, shortening 2 shearwalls. On the second floor, there are two obvious wood shear walls, but they are on opposite ends of the building about 106' apart. There are 6" dia. HSS columns about 24'± on center in between the shear walls. Right...

    What is Backstay Effect?

    Just read a recent thread about shear failure in a wall and it was claimed that it was backstay effect. I couldn't find a good description on google so I thought I'd start a new thread.

    Post Tension Anchor Minimum Slab Thickness

    I have a 5" post tension slab. At the edges, where the anchorages are, it thickens up to 7" which is typical. The contractor is asking to keep it at 5" at one of the cold joints where we have a pour strip to account for shrinkage. There is no soil around the area. I have never seen 5" at the...

    Shoring Point Loads on a 5 inch Slab

    @Archie264, Yes. I figured it was practical, I just thought I was missing something. They'll definitely need cribbing.

    Shoring Point Loads on a 5 inch Slab

    I have a 5" thick post tension slab in a parking garage. It's a one way slab spanning 18' from beam to beam. The contractor is putting about a 17 kip (D+L) point load (shoring load for floor above) about 3' from the beam on each side. He says he's done it without cribbing before (the footprint...
