    AS 2870 vs NCC

    Lots of interesting statements, and so many different ways for you to be reviewed (in Qld, qbbc, rpeq, small claims, courts to name a few). I do hope in Queensland that everyone who is designing footing for houses is using as2870 or a higher order analysis as referenced in the code, as the...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    Euler, I do a fair few building in high wind zones with ridge vents, I am yet to have an issue with local pressure factors once you take averaging into account or m2 rules etc. In regards to the study, you can reach out to he Queensland works department, they maybe able to direct you the...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    I do believe your referring to internal suction, not pressure, and your now referring to an opening in the roof with a KL=3 and 0.9, this would be a rare building, and permanent or debry roof opening are rare, and given that debry impact is reduced for most low pitch building to the point that...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    Euler, Some emotional words, radical, catastrophic, I doubt that anyone would be able to pinpoint any of the building failures to internal being under appreciated by the difference of this calc. Overall the change to the internal pressure with local pressure changes hasn't greatly changed the...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    The local pressure factor is ment to represent the external local pressure factor acting on the opening at the max event. There was a fair bit of testing done and a thesis was born and it does suggest that you are correct, the local variable pressure is still present with an opening. I think the...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    I thought it was Chris h on the NZ video where we asked but I can't find it ont hat video, but we asked one of the committee members during the presentations to clarify the intent. 1. For internal Pressure it is a factor for all internal pressure loading, no patch other than a check too see if...

    Revised internal pressure calculation in AS/NZS 1170.2:2021 Part 2

    Tomfh, Do you have this book? I thought they had an example in it, maybe not but if my memory serves me it did. https://awes.org/product/wind-loading-handbook-for-australia-new-zealand-background-to-as-nzs-1170-2-wind-actions-2021-electronic-version/

    750 AUD per year for Engineer Australia membership. Is it a joke?

    They say democracy is the poor form of government bar all others, I think this is much the same argument as rego for engineers and cpd vs costs. To have no rego process or cpd is not great for the profession, because sometimes it does work when we have engineers being signatures for hire. In...

    750 AUD per year for Engineer Australia membership. Is it a joke?

    I think an rpeng is similar to a cpeng, is what was being put forward.

    Movement in E type soil

    E class vs large settlements are two different issues. For E class you can control the flow of water and moisture around a building with good management practices. There are some pamphlets on this available on this for as2870.

    I need a sanity check - Drilled Pier depth determination in Lpile

    Does this substation have a slab connected to piers?

    Residential Framing Investigation

    I would ask for a few holes, we use snake cameras to keep the holes small in size.

    2024 Firm Personnel Changes

    This post sound very HR/recruitment, might be better moving this to one of the soft forums.

    Deflection limits for large-span PEMB frame

    Presets are a cost effective way to get some dead load deflection control. Presets are created by adjusting the bevel angle of the apex, hanch and splice cuts.

    Do you think it is right to design it as a 150cmx150cm column and rod element?

    The rods element has me confused, might be worth a google video on etabs and modelling. I am not an etabs guy but in my programs we would design the columns as frame/beam members

    Drift for frames

    Wind and seismic are different types of loading, generally wind has a service and ultimo drift limit, while seismic has only an ultimate drift limit. Depends on your location and type of building. Check out the info in the FAQ area.

    Lateral system for row houses

    In instances like this, I do homework to see what the contractor has completed previously and what drawings he had access too. Often I find that there is a perfectly acceptable solution, just the builder has no idea how to express the solution in engineering terms. I would ask for a few...

    Seismic Retrofit Argument

    Also get some legal advice on the grandfathering assumption, in my area grandfathering is per code published, not from said date.

    Seismic Retrofit Argument

    Existing building are a very grey area, and good luck to finding a balance between codes and engineering standards. My question would be used of the building after purchase? if you client intends to convert it front the original use of heavy manufacturing to something different, then in my neck...

    Glass railing wind load at balcony

    https://windtech.com.au/wp-content/uploads/2012/08/07.pdf I don't get why everyone isn't reviewing the test data, let's preference extrapolation from a code for 2d analysis to what is a 3d wind flow problem. In other words think fence vs building wall, they have very different wind behaviours.
