What is the standard way to splice rebar to form a longer rebar?
What is the standard way to splice rebar to form a longer rebar?
(OP)
In a tension concrete member, when the rebar is not long enough and need splice them to make a longer rebar, I have seen some contractor weld lap splice along overlap portion, some contractor use wire to tie the lap splice at overlap portion, some just let it overlap a development length and leave it. So what is the standard way in these overlap portion in practice?
Also in a flexural beam, is it allowed to splice two (or more) short rebar to make up whole length rebar in tension?
Thank you very much for your precious response.

It is a matter of specifying a splice length, either tension or compression, that will permit the reinforcing steel stress to redistribute to the next bar. There are several factors that determine the splice length and these are noted in ACI or CSA standards and likely other standards. Try to provide splices in areas of reduced moments, etc.

Lapping without tieing is not acceptable.

It is allowed to to splice two bars in same beam. But the splice should be staggered and should be avoided in maximum bending moment area.
