    Post Tension Slab Design for New Zealand

    A follow up on this thread (though not entirely PT related), I just found that NZ 12.5.6.9 Requires for additional Bottom reinforcement at support location called as integrity reo. This is something I have not come across in AS3600 and the ACI. It basically protects the slab for falling upon...

    Post Tension Slab Design for New Zealand

    Thank you @Agent666. When you do your peer review do you intentionally check it against AS3600? What do you do when some clause in AS3600 is not met? Do you consider it as strict compliance?

    Post Tension Slab Design for New Zealand

    I've been doing PT slab/beam design in Australia for more than 5 years and I would say AS3600 has a straight forward requirement and easy to follow guidance. I'm recently involved in PT slab design in New Zealand and I was surprised to find that the code is not as straight forward as that of...

    Ignore pile capacity for embedment < 3D

    Thanks, Ron. Is it something that is code defined or more of an engineering practice?

    Ignore pile capacity for embedment < 3D

    I am working on pile design and I was advised to ignore the capacity of the edge of the pile if the embedment to the soil layer is less than 3xpile diameter. Please refer to the attachment for clarity. I have not used such assumption in the past and I am wondering if anyone came across with it...

    Slab Stiffness (AS3600)

    Thank you in advance for giving your time to address my question. I am modeling a flat plate in ETABS and I am trying to figure out what stiffness modifier should I use. I know ACI gives this value to be 0.7 for Column, 0.35 for Beam, and 0.25 for Slabs. I am designing the structure for...
