Would anyone ever consider framing a new roof on top of an existing PEMB? I have someone who has adjacent pre-engineered metal buildings and wants to frame a new roof between them to get rid of the valley. Reasons to not do it:
1. Expansion/Contraction. Tying 2 buildings together with framing...
Does anyone have any info on the structural cost increases to projects conforming to the new federal "Build America Buy America Act"? Or any recent articles where this is addressed?
For those of you familiar with coastal flood design, I have a small project where an Owner wants to build an attached garage to an existing home in Flood Zone AE. The existing home was built prior to the most recent FIRM and the FFE of the home is at 13' and the BFE is at 18'.
The building...
Can drywall studs which are non-structural/non-load bearing be used in tension. Specifically these studs:

I have a project where a contractor has hung very large sections of wall from the roof deck. The work is...
Many good lessons for Engineers on this failure:
1. Designated Connection Design. Do you designate others to design the connections on your projects? Guess what, if it fails you will be sued. In fact, everyone on the project team gets sued - architect, contractor, structural, electrical...
Winelady,
The deck is not spanning in the direction shown on the plans...its spanning in the other direction driving all the load to the perimeter W10x19...Try W10x19 spanning 25'-9" with 24' of trib.
So why didn't the separate application catch the problem (if, indeed, it is a problem) before importing or translating into REVIT?
It not the job of the computer program to "CATCH THE PROBLEM". It is the job of the engineer to know what he is doing.
How about some basic span to depth ratios...
REVIT is BIM modeling...It is typically not used in the US for structural analysis...it has replaced CAD for providing Construction Documents...I would guess that in Louisiana most designers would be using Bentley's Ram Structural System for analysis.
During the initial stages of the design...
I have heard the Hyatt Regency collapse in Ethics Seminars over the years so many times, that I literally cringe when I hear a speaker bring it up. Mark my words, this will be the new Hyatt Ethics Seminar.
My hope is that somehow NCSEA and state MOs will use this to push state legislative...
Dold...You get a star for your W10x19 girder comment!
Let's hope those plans you linked which are sealed and do not state NFC are not what was used for construction!!!
This is going to be a PRIME EXAMPLE of Why Practice ACT Structural Engineering Licensure should be Mandatory in all 50 States.
Louisiana is a Title Act State...Previously if you passed the old SE I exam, your were licensed as a PE, but Structural was listed as your field of work.
I just...
Check out the steel framing and deck orientation in the cantilever...where those small canti tubes supposed to hold the floor up? The shoring appears to fail, but this appears to be some weird, inadequate framing
For current IBC Load Combinations for Aluminum Bleachers, do Horizontal Sway and Wind Occur at the same time? Isn't Horizontal Sway due to people (live load) in the stands and you wouldn't have people in the stands during a Hurricane???
If anyone has ICC 300 and could provide the Service Load...
