Reinforcement Detailing Good Practices

[Stoppie]

Hi all, first post here. Firstly a thank you to this community. What an invaluable resource!

I have come across a few good practice tips in detailing reinforcement, that aid other parties to provide quality work, such as:
* limiting bar lengths to fit onto a pickup truck for small (residential scale) projects to allow contractors to collect the reinforcement from the fabricators themselves.
* limiting bends on bars to 4 bends (where possible) as more than 4 bends become difficult to handle and form in the machines used.

and was wondering what else there may be. Please share your experience.

Thanks... maybe for some residential work the first one might not be practical for main steel... and it poses a bit of a hazard for people following a pickup truck from behind. If possible, it makes sense, though. I've not done a lot of residential work, though.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

A few useful ones I have learnt, which might be specific to where I live:

*Where it is allowed by the code (e.g. shear reinforcement in a slab), contractors often prefer to use a two-piece stirrup with lap splices for the vertical legs, rather than closed stirrups or bars with both ends hooked. Easier to install and adjust on site.

*When detailing fairly dense reinforcement or where dimensions are important, I now make a habit of considering the bar to have an overall diameter of 1.2x the nominal diameter, to account for the largest size ribs allowed in our reinforcement standard (i.e. max rib height = 0.1x bar diameter).

Gusmurr, how deep are your slabs, or how small is your shear reinforcement to get a lap splice in the slab depth?

Slab is probably the wrong word. The example I was thinking of were 1000-1300 mm deep 'slab-like' column headstocks that formed part of a train station overpass.

But we often get asked to provide the same detail for the internal shear reinforcement in beams, pile caps, etc.
