Lap lengths in columns
Lap lengths in columns
(OP)
Hi,
I was curious to know what type of lap lengths you allow for in columns?
Where I live we seldom use bars larger in size than 32mm diameter.
Thanks

40db is a good rule of thumb.

I my opinion, Tension lap is required to be able to develop moment resistance for lateral displacement capacity (Seismic / Wind)

I was just interested to know because if you use #18 bars and 40*Ø lap you end with a splice in excess of 2m long. That is basically two thirds of your floor to floor height. I would imagine it is cheaper to use mechanical splices then.
As I said, not really applicable to something we do here. I was just interested in the type of details you guys do on the other side of the Atlantic.
