See the attached pdf. The concrete slab rests on a "2/2 V Grip Deck". V grip deck seems to be Inryco (https://www.eng-tips.com/viewthread.cfm?qid=361447), but I have no idea what the "2/2" means. Anyone have any idea about this nomenclature...
Does anyone know where I can find the booklet guide from 2006? Only 2010 and 2018 show up on google. It's for litigation purposes so the booklet used at the time it was built is important. The only reason I know 2006 exists is it's reference in ESR 1553. Thanks
Malone has a workshop slide show and a publication regarding wood diaphragm discontinuities links to which are posted below. I unfortunately don't have his book.

I've been pouring through the provisions for the better part of a day, and I keep getting hung up on 11.6.1, specifically where it says "... These limits need not be satisfied if adequate strength and stability can be demonstrated by structural analysis".
So, for my basement wall, I can have...
In my area, what people call a single boarded house is one that lacks wall studs or columns. Instead, the wall framing is comprised of a continuous panel of discrete vertical plank members. The planks are fastened to rim beams and end joists. The connection is made by lapping the plank to the...
I have this large conical wood roof that I'm analyzing (see attached sketches and a photograph).
The building has been around for over 100 years. The only issues are some bowing/buckling/warped struts.
The only way I get the analysis to meet reality is if the transverse roof beams (transfer...
If I'm anchoring to steel to a concrete wall in a bearing type connection, as in, I'm using adhesive anchors into concrete and hanging steel from it, must I abide by Table J3.3 and Section 2 in the AISC which states that oversized holes cannot be used in bearing type connections. It seems this...
I've been reading through American Building: Materials and Techniques from the First Colonial Settlements to the Present by Carl W. Condit, and Ancient Masonry by Batty Langley is mentioned in the text. It seems to be a prominent book in the 1700s for construction showing details and design...
I've seen other threads about the deck, but I can't seem to find the one specified on these old plans.
Here's a direct quote from the drawings "1-1/2" Steel Roof Deck. -Robertson
"Q"-Deck No. 3"
The drawings are from 1950. The deck is for a roof. It does not have concrete just insulation and...
I was talking with colleagues to see what elevation they use for calculating MWFRS windward wall pressures:
1) Top of wall;
2) Average wall height;
3) Take qz evaluated and top and bottom of wall and take average;
4) Some other variation like qz evaluated at 2/3 the top of wall height.
I can’t...
I have a specific situation where we may use reinforced brick masonry to repair a brick wall corner that was severely damaged due to a demolition project (see repair detail below for rough schematic).
I have read through Brick Masonry Institute technical notes 17 & 17A. They say that brick can...
ACI Section 14.3.4 states:
14.3.4 — Walls more than 10 in. thick, except basement walls, shall have reinforcement for each direction placed in two layers parallel with faces of wall
in accordance with the following:
(a) One layer consisting of not less than one-half and not more than...
There's a manufactured home that's being relocated. They want the new location to have a full basement.
There will be 5 steel beams to support the chassis beams. These steel beams will sit on pilasters integral with the a 6" thick concrete foundation wall. Since there is no way to easily attach...
I have a steel portal frame columns fastened to reinforced concrete piers.
In ACI 318-11, figure RD.5.2.9 show the anchor tensile reinforcement on the outside of the anchor bolts. I have a large base plate on the pier and there isn't much room outside the anchors for additional reinforcement...
Table 4 in the tek has allowable moments for lintels. I tried verifying the designs but am getting significantly smaller allowable moments for 8" lintels than those posted in the tek and can't seem to trace the error. Has anyone else successfully verified these capacities?
I have attached a...
There is a warehouse who's roof is significantly deflected (due to large amounts of snow) and I'd like to not go back inside to identify the steel roof joists. The building is currently evacuated due to the roof deflection.
Here is a photo of a tag from the bar joists:
As best as I can read...
I have a situation where I need to be certain that a beam has a pinned and not a moment connection. It's a clip angle with a two bolt connection to a beam and 2 adhesive anchors to a concrete wall. The adhesive anchors can't take the full moment.
I wish to horizontally slot the top bolt hole to...
I have spreadsheets for both methods from AISC Design Guide 1 edition #2. I sent the triangular distribution method to a friend and he found an interesting situation where the anchor rod tension is negative even though e > ekern. I for the life of me cannot figure out where the error is.
