So it was released a few days ago with no fanfare, after a 29 year wait...
Some things from the draft retained which I thought would be gone or clarified further.
Axial load capacity got crapped on, it's like no one calculated anything to compare. Or if it was the intent no one bothered...
All of the current advice I'm aware of with respect to web penetrations in steel members (AISC design guide 2, AS/NZS2327 and SCI p355) only covers the treatment of web penetrations in i-section members.
P355 sort of mentions some of the concerns I have with a non symmetrical tee (web and...
After some advice on CLT floor connections between floor panels under diaphragm actions (transferring shear along joints).
I'm finding from a strength perspective we need fixings in joints at very close centres, we can work out the capacity of a screw at minimum spacing, but at some point it...
Hi all, does anyone have any experience with attaching CLT stair flights to landings? I've been trying to find a idea of how they are typically detailed but it's like it's some state secret that no one letting on about.
I'm talking about the connection at the top of a flight to the main or...
I'm referring to Eurocode 5 (in particular Annex B & C of EN1995-1-1 2004 - Design Of Timber Structures, Common Rules And Rules For Buildings) where formulas for assessing the effective stiffness (EI_eff) of 3 built up members is given in B.2.
I was wondering if anyone familiar with the method...
A couple of days ago in freak wind gust (120km/hr reported) a truck tipped over and hit one of the diagonal struts on the Auckland Harbour Bridge shearing off the bolts and causing structural damage to the strut.
Another truck was tipped over onto the median barrier...
Hi all
Does anyone have an example applying the provisions in AS/NZS2327 appendix C clause C3.1.3 relating to openings in steel composite beams? This is with respect to determining the compactness of the tees at an unstiffened opening, in particular for non-compact and slender tees.
Quite...
Hi all
In ACI318-19 chapter 17 (and earlier versions appendix D) :-
For checking combined actions on anchors if you are foregoing the shear and/or tension concrete breakout checks in lieu of adding specifically designed anchor reinforcement in accordance with ACI provisions. ACI isn't quite...
Hi All
This is a tricky little scenario that we've been doing some circles around for a while trying to figure out a best practice practical approach.
It's related to concrete breakout capacity of anchor groups in shear, particularly for shear acting towards an edge (but equally applies to...
In this day and age of working remotely, one thing we seem to be struggling with is a workflow that works efficiently with respect to dealing with drawing markups for drafting and concurrently drawing those while engineers continue marking up even more changes.... Rinse and repeat
On recent...
Not much about the causes, but interestingly next to no traffic on it due to the lock down in Italy.

So I was working through trying to teach myself the equivalent frame method from ACI318, specifically looking at some of the examples in ACI421.2 related to flat plates. But for the life of me I'm not getting the same answer for Example 1 (see attachment below). In particular my main question is...
We are looking at getting involved in a structure with a considerable vertical load transfer beam structure at the lowest level.
This consists of proposed long span PT beams supporting up to 5-6 levels of building structure above, typical ~8.5m grids, transfer beams supporting two columns...
In AS/NZS1170.0 for determining the importance level of a structure, there is one provision that doesn't seem so clear cut (highlighted below). All the others are easy to evaluate as applying or not, however this one seems to be open to interpretation.
What is peoples interpretation of this...
Hi all.
In the last couple of years I've seen an increasing number of businesses moving towards embracing producing calculations by electronic means. By this I mean rather than using pen and paper and handwritten calculations and scanning them in from years gone by, the calculations are for the...
What are peoples thoughts on this situation:-
Both AS & NZ steel standards allow the use of alternative design provisions for combined actions, i.e. if section is compact, is a doubly symmetric I section or a square hollow section alternative equations can be used in chapter 8. NZ code has some...
Hi all
A question about the application and determining the k_t factor from table 5.6.3(1) of AS4100 or NZS3404, just something I was wondering if anyone else had come up against this scenario, and how you may have treated it?:-
Brief background to the question, writing a few python scripts...
This hopefully a simple followup to my previous thread on this subject thread507-445334
I had a further question on the clarification of one point in working through implementing it in practice for those that participated, namely Rapt/Southard2/IDS, or anyone else that can contribute:-
In...
Anyone else think this is a recipe for disaster waiting to happen, on site practices with respect to grade 500 are pretty poor (at least here in NZ), limited respect for bending/rebending requirements, contractors inadvertently welding it, or welding without proper welding procedures in place...
