in the 2022 CBC Sec 1905.1.8 ACI 318 Section 17.2.3, section 17.10.5.3 (d) requires the seismic overstrength factor for wood framed shear walls, 3.0, to be applied to the net uplift load at wood framed shear wall ends. When combined with all the ACI limitations on concrete breakout and...
It's been a few years since I've had the occasion to design an OMF in a custom home in CA, but just got one recently. In the past, I've used a prequalified, WUF-B beam-to-column connection. I used to call that a "prequalified" connection, but maybe that isn't the correct terminology anymore...
This feels like a stupid question but does anyone know where to find the Commentary for the CA Existing Building Code? I've been searching around on the web but nothing is coming up. Only thing I can find is the Commentary for the 2021 IEBC. Is that all there is?
I am having a dispute with a...
Current angled holes meet all minimum edge and end distances for both sills and concrete. This is a retrofit of an old building to a foundation that had no anchorage to the concrete at all. Holes are drilled about 4 1/2" into the concrete (specs call for 4"min embedment)
Extra labor would be...
Tried Simpson already. They had no guidance on it.
There are about 55 holes drilled this way. Lots of labor to correct, so seemed worthwhile to try to find a resource to buy it as-is.
My gut feel is that it is OK. I just need to present an engineering rationale for that. Shear seem...
A builder drilled holes for 5/8" Simpson Titen-HD's to be retrofit into an existing concrete footing about 20 degrees off vertical because of some as-built constraints in the building. Off vertical to the outside, not length-wise to the sill. The building inspector caught this and said he had...
The project is still in design, so client doesn't have a GC yet. It is on the east side of the Sierra, about 250 miles from So Cal sources for pre-cast products. Maybe Reno or Las Vegas could be options. Transporation costs for precast hollowcore planks might be daunting. Especially for a...
Most of my 30+ yr practice a has been residential and low rise commercial and light industrial. The only elevated garage slabs over conditioned space I've done over the years have been single car garages. I now have a big luxury home with a 24ft x 24 ft elevated garage over conditioned space...
I normally do about 95% of my work in ASD. I booked the engineering for a 5000 sq ft 3 story custom home in a very high seismic and snow load region (Sierra Nevada). The local Fox Blocks ICF folks have sold this client on doing all his exterior walls in ICF's, so now the home will have all...
I am looking for other professional opinions as to whether or not this building should be classified as a Type 5 Nonparallel System Horizontal Structural irregularity or not per ASCE 7-16 Table 12.3-1. See attached plans
Owner wants to build with light wood frame construction and thus wants...
I think Ron247 gets the drift of my dilemma. Frankly I'm not too worried about liability issues, even though we're talking about condos, for the most part. The plans are what they are. They may or may not include all the change orders etc. The biggest benefit is often just having dimensioned...
I've spoken to the local jurisdictions (city & county) and they would be happy to take any plans I have off my hands. But not pay for them. Why would they? They provide any digital plans they have on file to any property owner for free (once the licensed professionals still in business OK it)...
I' d like some advice as to what you folks think I should charge HOA's for copies (digital scans) of stored original blueprint build sets of plans for condominiums complexes that no one else has. I used to charge the per page cost of the scans plus my time plus a $250 archive fee. It occurred...
BigH, "2x width for square footings or 4 x width for strip footings. Footing width of 450 mm means that the zone of influence is between 900 to 1800 mm. One has now confirmed the upper 150 to 200 mm; one has not confirmed the zone below this testing depth" I had the same thought looking at...
Excellent technical advice from everyone. As always I can count on the ETF experts for well-reasoned and experienced advice in engineering areas I'm not as strong in. So glad this forum exists. Thank you very much.
