    Alternating 180 degree cross-ties?

    Right guys, I agree totally agree and am very used to these designs and have installed and inspected many myself, I myself not being an engineer but self admitted powerful lust for knowledge of how and why things work. The kid the disassembled and reassembled everything!!! I've built much bigger...

    Alternating 180 degree cross-ties?

    The funniest thing about all this is the general note that says to "alternate ties in successive layers." It's not what you know, it's what you can prove.

    Alternating 180 degree cross-ties?

    Yes, Lex, indeed it is far too tight, they are using a concrete mix with 3/8 pea gravel on the pedestals, which helps. At a minimum the additional length of the tail is totally redundant. In addition to the overkill of closed inner ties. There are top, mid, and bottom corner bars for grade beam...

    Alternating 180 degree cross-ties?

    Indeed dik, rapidly approaching a hellscape!!!! It's not what you know, it's what you can prove.

    Alternating 180 degree cross-ties?

    Thanks, Just Some Nerd, agreed, I think the rodbusters unwillingness to fix such mistakes just shows their lack of planning and attention to detail or maybe just plain ignorance...."There's never time to do it right, but always time to redo it." On another note, and back to my original...

    Alternating 180 degree cross-ties?

    And I've been told I need to lighten up, I usually enjoy humor in hindsight, maybe I'm too literal. It's not what you know, it's what you can prove.

    Alternating 180 degree cross-ties?

    Right, I apologize for snapping at you... Lol Everything here is engineer approved and fabricated, and I do remember reading in ACI where it talked about the uneconomical use of such hairpins, thanks. It's not what you know, it's what you can prove.

    Alternating 180 degree cross-ties?

    dik ... have the hooks facing the opposite direction? ponder?? This is an idea I posed in the original post, and asked if being on the opposite side of a longitudinal bar benefitted the design strength. [highlight #FCE94F]2. Would that alternation consist of the continuous "leg"...

    Alternating 180 degree cross-ties?

    Thanks for all the responses, seismic is doubtful, we're in SE Texas, not sure if it matters, but none of the job is pile supported and it's a pipeline compression station if that matters. The job is in progress, just came on as QC and pretty sure QA will require RFI'$ for clarification. I think...

    Alternating 180 degree cross-ties?

    Hello all, I am aware of the need to alternate the ends of the 90/135 hooks, on this project all of the cross ties are detailed with double standard hooks of 180 degrees, and the general notes states, "Location of hooks and direction of hairpins shall be alternated in subsequent layers." This...

    Alternating rectilinear hoops

    Hello all, I cannot find and hopefully it doesn't exist..... Are the 135 degree hooks on rectilinear hoops required to be alternated from one corner of a column/pedestal to another? I've seen it both ways: All hooks on one longitudinal bar and rotated as mentioned. I'm being challenged by a...
