    How to place minimum steel in a rectangular footing?

    I agreeed with BA, the top face of thicker footings shall not have without any reinfcrcement, or otherwise make the footing tapered (If not uplift) at the end or otherwise expect cracks. But what is the limit at which footing acts as thicker?

    Mininum dimension at end of tapered cantilver beam

    Hi BA, I am thinking to convince architect for a minimum of 24" at end, just for placing rebars easily. Looking for any design literature to check slab thickness for triangular shape slabs. I am using BS code, it gives me moment formula, but not how to check thickness of slab, like l/33 or...

    Mininum dimension at end of tapered cantilver beam

    For information at support, beam dimension is 26"x48" deep, which is more than the required dimensions, satisfying the short and long term deflections. Lookinf for minimum 26"X? at end. Architect requires 16".

    Mininum dimension at end of tapered cantilver beam

    As per attached sketch, what should be the minimum dimension at the end of tapered cantilver beam. Normally it should be half of that at support. If beam depth is more than required, is there any codal requirement for minimum depth at end of cantilver.

    Glulum modelling in ETABS

    Have some modelled wood framing in ETBAS. Just wondering, can we just analyze or it can be done modifying the steel or concrete material properties. Originally there is no wood design tab in ETABS.

    Estimation of rebar and concrete quantity

    Can we estimate approx. quantity of rebars from Etabs. I can see concrete volume, but steel weight can be a big difference on quantities.

    Stirrups placement in cantilvered beams

    I agree, if the architect does not want a simple shape, how it can be built simple. I am also thinking to specify varying stiruups sizes.

    Stirrups placement in cantilvered beams

    Thanks BAretired, Just wondering, is it easy to control that spacing pattern on site. Any limitations expected for placement, which would be dangerous, i mean any arrangement which cannot be monitored on site easily.

    Hi Apsix, Appreciate if you can give a sketch for your idea.

    Slender Column

    there is another way to make your top story as master and then column will display in full height. One of my collegue did this. I will double check it for you tomorrow.

    Stirrups placement in cantilvered beams

    Normally stirrup hooks are on top for simply supported beams, is it not good that hook for cantilever should be at bottom face on compression side.

    Stirrups placement in cantilvered beams

    As per Canadian Code, it is allowed, only concern is placement problem. I don't like either lapping the stirrups too. See Canadian code recommendations regarding stirrup lapping.http://files.engineering.com/getfile.aspx?folder=1033b9fa-8cb3-4b33-82de-8bdfa7f89c34&file=SK.pdf

    ETABS different roof elevation

    apply loads manually at each diaphagms. assign each level as different diaphragm and apply forces at column faces or diaphragm centre. Auto lateral forces have to be double check all the times.
