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.

Does this substation have a slab connected to piers?

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

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

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.

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

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.

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...

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

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...

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.

Rofail and man's 2003 windtech consultants is an Australian research but maybe of help.

Also depending on what your doing, we could have a wood armer issue.... The list is long.

How do they calc J, is it similar?. I would suggest a simplistic J calc is used by 1, the other wouldn't need it.

thread507-506874 This book "design of portal frame buildings" has been updated for the latest AS1170.2-2021 code interpretation and should be correct in it latest publication (I asked the ASI to send out new books to anyone that had purchased it before the update). If you feel the latest...

Basically air gets trapped between the solar panel and the roof, this acts like an internal pressure pushing up and down, up in the panel down on the roof. For this case the solar panel to receive both an external suction and a pressure which in the first case would be -1.1 + .6 roughly to make...

In cold formed portal frames knee braces are very common. The connection design is made easier with knee braces turning it into tension, compression and shear design, as moment connections are more difficult in cold formed.

I don't see the jump from parapet to section B.

Microstran is a beam type modelling software, how are you handling the floors, walls and ceiling diaphragms? If you are representing these are strap bracing then your distribution of loads will be different to the load distribution assumed thru the timber codes. If your doing grillage type...

Interesting question, I thinkt he code you also need to read is as5216, this forms the basis for most connection design you are referring too in your post I believe, if I don't have this correct please provide more info as to the specific connect you are referring too.
