Re: Control joints in Elevated slabs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hyndman,

Well as you know it already, CONTROL JOINTS are infact a 'desired location' where you actually sort of train or want the crack to appear.

CONTROl JOINTS are not heard of in an elevated deck slab; in the frames & in the slab all you do is provide an 'expansion joint' to take care of expansion/contraction in the frames due to thermal movement in the same; depending of course on the length & shape of the structure.

CONTROL JOINTS  are normally provided in:

    -  slab-on-grade,

    -  screeds,

    -  CMU  (masonry), etc.

Anyone ever heard of putting control joints in elevated concrete slabs on
