Does anyone know of a resource to clearly show when Overstrength is required based on seismic design category and building component. The information is just littered in the ACSE and some info in the ACI. A flow chart makes too much sense to not exist. Thanks in advance!
"SDWC15450 (this is the black one) is recognized for use in chemically-treated wood as described in
the evaluation report." - This is what the simpson book says - It says chemically treated not exterior use. Where most screws in the simpson book explicitly say exterior. How do you read that?
I am hoping to use some truss screws like SDWC’s. I need ones are for exterior use though, and It doesn’t look like I can use SDWC or its values exposed to weather. Anyoneknow of any exterior use truss uplift screw and have access to its values. Owner wants screws for aesthetics on an outside...
The roof attached is the one that fits the one I am designing for. The height is roughly 30'. I am not used to designing with this 0.6h number for what I would normally call "a" which is the minimum of 0.1 L and 0.4 H. This 0.6H from both sides will make the entire building a corner zone. Is...
I am familiar with the canopies section, and although I doubt it would be allowed in my scenario. My interpretation is there must be wall above the "overhang/canopy" to allow for the use of those values. With no wall a typical overhang will have wind moving a lot faster over the top than below...
Attached now. Where are the guidelines you are talking about. Is it your opinion that the wall pressure needs to be applied over the entire overhang, regardless of width or height of the wall its connecting...
I have a roof with a large overhang, 12'-15'. In the attached diagram from ASCE 7-16 The value Ps,(pressure from the underside of the overhang)is the wall pressure value from the wall below the over hang. I believe this value is from wind hitting the wall and running upward to continue its path...

Similarly, if anyone knows of a chart for a reinforced top chords (4 angles instead of the standard 2). that would work, the Canam catalogue had higher values for higher shoe depths but nothing on larger top chords.
I probably wasn't clear, I am trying to verify the cantilevered exertions will work on my roof joists. There is roughly an 11 foot overhang. The typical joist seat extensions give values up to 6 or 8'. But these are 2.5" joist seat extensions. A 5.5" should definitely be able to cantilever...
Is there a load table for a joist seat larger the standard 2.5" joist seat. I am looking to extended a 5.5" joist seat around 10 or 11 feet. With the 2.5" values this seems very doable but I am not finding nay solid values on what the larger joist seats can span. Any info is helpful. Thanks
I will probably end up using those but they are a little weak for what I need. I'll make it work if its the best they have. I was just thinking a base like a MPBZ would be stronger, so i was hoping they would have a product that wrapped the bottom of the beam like a MPBZ but was able to be...
Aesur, Thar product was exactly what I was looking for, do you know of a post-installation post moment connection. The ones I am finding are all cast in place.
