Hi All,
Just curious as to what others are designing for in terms of a mu value for block buildings?
I had a certifier query a design for a building that was 5 levels but >15m and used block everywhere (including shear walls and cores). He said other engineers (in Brisbane) had told him that...
Hi all,
Curious to get opinions on the attached for max spacing of vertical bars, specifically clause AS3600 cl.11.7.3. and the 350mm requirement.
If the bars are staggered as per attached then max spacing between vertical 'parallel' bars is around 240 if they are spaced @ 400 on each face and...
Hi,
For multistorey buildings I was taught to design the cores and nominated shear walls (if needed in addition to the core/s) to take the lateral EQ load. This approach is no longer valid. There is plenty of threads on here to explain why (special shout out to Rapt for his input to those and...
Hi,
Im interested to get peoples thoughts on using cable ties in lieu of tie wire for securing ligs in the boundary elements of concrete walls. Clause 17.2.5 states "tie wires shall be used..."
Does anyone know why the code is so restrictive (shall not should..) for using tie wire given...
Hi,
I am hoping someone has a copy or access to SAA Int. 352 code. This code was one of the predecessors to AS1551.
We are doing an assessment of an existing structure and require the weld electrode strength. If anyone can assist that would be great.

Hi,
Does anyone know if the requirement for safety mesh is codified or where to find references for it?
I am referring to the mesh contractors/builders put down for beams/slabs over 300mm thick to stop workers falling through.
Thanks in advance for any replies.

Can the engineering community help us resolve a fairly simple question? The attached pic is for a site in region A4, Victoria.
Its for a 10m high circular tank with a 3.5m diameter.
If you were designing it what terrain category would you take as a rule of thumb if using an Md = 1.0 ie not...
Hi all,
We are connecting a new concrete beam to an existing 500mm thick reinforced wall.
My question is if we are relying on shear friction to provide essentially what is a pinned support to the beam by dowelling into the existing wall - can I pro-rata the shear friction capacity of the...
Hi all,
I have a question regarding AS1170.2 Appendix E.
We have been asked to provide an incremental base wind pressure for a rectangular steel silo supported on a steel frame. The overall height is 25m and in plan 11 x 4 m.
Can I utilise the aspect ratio correction factor (Kar) in T.E1 to...
