clicking through shows it's a permissions error, server-side. I can't be sure whether it's the graphic file itself, or the enclosing directory/ies. You will sue if it's not to code, yes? pretty much means not moving in...
I am going to prevail upon their professional integrity...If they got it wrong, it needs to be fixed.
The "guranteed equivalent" of the W12x26 steel section originally specified is a 50% deeper LVL beem (21" instead of 14").
When I run the same loading case on even an 18" beam, or a 16" beam at 4 plies instead of 3, it passes... A cantilever load is one where the load is spread across a beam having a point of support that
isn't on an end. This causes deflection to follow a more complicated curve, which is generally
flatter overall than a basic catenary. I really doubt it applies in your case.
The usual approaches (assuming the beam is currently in place) depend on how the
beam is expected to exceed parameters. Some failures (such as twisting) can be
helped by adding steel L channel to the beam's corners. Otherwise, the beam is
usually either sistered with another beam to build up an acceptable cross section
(I did this in my house), supplemented with a steel I-beam underneath it, and/or
additional support columns added. The I-beam approach lowers the ceiling and is
therefore not generally preferred. Adding a column generally puts a post in the
middle of a room somewhere, which may or may not be a problem depending on
the view and whether it could be hidden inside a wall. So sistering the beam is
probably your best bet. Argh! The structural is coming back to me. Must hide.
I wish I could help you, but I've purged my brain of any structural knowledge. ![[User Picture]](https://l-userpic.livejournal.com/62606638/387157) | | From: | ladysea |

If you are really uncertain, and not sure what your builders are going to say, take it to the city/county engineer and ask them to look at it.
It is always a good idea to get a second opinion, and they would be the people to ask.
I know in commercial builds, all of those things have to be checked by the city engineer's office, but I know little about residental builds.
*remembers the days of driving rolls of plans all over the place to get them approved* I'm surprised they didn't catch this earlier... hope it's not too hard to correct! |
