Hey guys,
I've been using the original 2018 version of AS3600 and the changes to the Vuc capacity of beams has been brought to my attention.
It seems embarrassingly reckless to remove the reduction of concrete shear capacity in the 2018 version only to significantly reduce the capacity in a...
Hi Guys,
Just was having a browse of the AS3600 Commentary regarding shear reinforcement development.
8.3.2.4 states
"Shear reinforcement shall be deemed to be anchored provided the following criteria are
met:"
b) "The fitment spacing shall comply with Clause 8.3.2.2. Provided the hook...
Hi guys,
Just had a bit of a discussion at work regarding how developed (in terms of strength) a cogged bar is at 0.5Lst past the back of the cog.
My understanding has always been that if you have a standard cog to AS3600 and provide a straight length in the other direction of 0.5 x Lst then...
Hi all,
I'm designing a diesel tank 14m Diameter, 15m high tank with a fixed roof (rafters and roof plate).
Max inlet flow rate = 870 m^3/h DN250
Max outlet flow rate = 440 m^3/h DN250
Tank is at atmospheric pressure
I'm a Structural Engineer and haven't had any exposure to the Venting...
Hi Gents,
I don't do a lot of concrete design, reinforced concrete footings mainly. I was always taught to check "beam shear" in concrete at do from the support. While reading AS 3600 it says regarding checking shear near a support in the attached image. In regards to checking Shear at do from...
Hi all,
Little bit of confusion from Figure 5.12 about what is allowed in regards to welding reinforcing bottom plate and the other bottom plates. Section D shows a bevelled Reinforcing bottom plate with full pen butt weld with 32mm overlap (which appears to be around the shell interface, but...
Hi Everybody,
I'm designing a 3m dia, 3.5m high tank to API 650 and the client would like a 600mm Flush clean out door. The problem is if you follow the dimensions in Table 5.9a, the bottom reinforcing plate becomes like half the bottom plate and looks quite excessive and has already been...
Hi Guys,
I am placing a pipe support cleat onto the tank wall and need a reinforcing pad at the cleat connection. The proposed location is on or near the horizontal strake joint. Is there a minimum distance the repad needs to be from the horizontal joint? This isn't a shell cutout so I guess...
Hi there,
We have a pipe between tanks (DN350) that is on quite an acute angle so the vertical hole in the tank is roughly 700mm long in the vertical. Would I treat this like a Dn700 pipe repad and specify a 1440 diameter repad? Or is there scope to adjust the width to a narrower repad and...
Hi Gents,
Im a Structural Engineer (Australian) and have a few questions regarding the API 650 code. I've designed some small tanks/hoppers etc before (not using API), however in a new project I'm taking the role of Designing some CIL tanks (10m Diameter, 12m high) for a gold plant. I'll have...
