Stirrups design Stirrups design ASultani (Structural) (OP) 26 Apr 15 15:31 Hey guys I am new in this site I just wanted to know how can I design stirrups for the critical length of columns it's formula or any information Thanks RE: Stirrups design hokie66 (Structural) 26 Apr 15 20:33 In columns (which are compression members), the ligatures are normally called ties, not stirrups. Stirrups are shear reinforcement in flexural members. Your concrete code will have provisions for spacing, size, etc. for column ties. RE: Stirrups design msquared48 (Structural) 26 Apr 15 20:39 Columns have ties and beams have stirrups. Mike McCann, PE, SE (WA) RE: Stirrups design JAE (Structural) 26 Apr 15 21:00 hokie66, don't the engineers in Australia (or is it England) refer to stirrups as links?

Maybe from English trained engineers here. But the normal word is stirrup. RE: Stirrups design Trenno (Structural) 26 Apr 15 22:25 Column ties and beam ligs (or ligatures). (Aus) I've even seen beam fitments. RE: Stirrups design KootK (Structural) 26 Apr 15 22:31 If you're concerned about column ties in the plastic hinges of special moment frames, that is code mandated too. It's in the seismic section of ACI 318 and results in pretty dense confinement reinforcing. I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Yeah, but you're a "banana bender" - Queenslander RE: Stirrups design ASultani (Structural) (OP) 29 Apr 15 04:49 Okay guys thanks But how to design the ties for the start and end of columns? RE: Stirrups design jayrod12 (Structural) 29 Apr 15 13:49 If there's a lot of bending and therefore shear, you design them the same as you would beam shear. Elsewise design them as containment reinforcement for your vertical bars and maybe add a couple extra at the top and bottom.
