Steel connections

[ajk1]

I believe that I have always known the steel angles that connect a steel beam to a steel column as "headers angles". But someone is questioning me on this and I am trying to find where this might be defined. Does anyone else use this terminology, and if so, do you know where it might be defined? I did not see it in the CISC Steel Handbook pages on connections, although I do see the word "header" in my 1973 edition of the CISC Steel handbook, in the French-English dictionary therein.

Double angle and single angle beam connections have been used by CISC for as long as I can remember. Header angle is not familiar to me.

Not as "header angles" but the small angles under a beam used for resting it during construction might be called that.

ajk1, I refer to them as header angles as well.

There is a CISC publication (I don't think they update it anymore) called "Standardized Shear Connections" by J.E. Henderson. He refers to this connection as header angles.

Thanks everyone for the responses, and particularly to CANMETT for this information. I take it from this that I was not incorrect to use the terminology "header angles" but it is perhaps not a terminology that is generally used, judging by the other responses. I will check with some of my colleagues in the office on Monday, whether they use this terminology and let you know. Thanks again everyone. Much appreciated.

I believe another term used is "clip angles". I have never heard of the connections being referred to as "header angles" but luckily if I hear someone use this term I will know what they are talking about (thank you).

Also, an angle that a beam sits on during construction would be referred to as a "seat angle" or "angle seat".

I have encountered early drawings where the connection angles are referred to as header angles... I can't reference them; it's been several decades...

CANEIT,

Does that publication also have connections for diagonal brace connections?

 

[CANPRO]

Althalus, it does not. Only has typical shear connections for standard size beams.

This morning I spoke to our chief engineer who used to work for the CISC about 30 years ago before he came to us (he is several years younger than I). He says very definitely he used the term "header angles" for steel beam connections. I believe I first learend this terminology about 1965. I was astounded by the number of engineers who say they never heard of it, but most of my work has been in reinforced concrete. Could this be one of those terminologies that is falling into dis-use? Maybe that's another problem with my getting up there in age. In wonder what steel fabricators would say to this question.

May be just a Canadian term. I have never before heard it used in the US or Australia. The derivation would be interesting, as the word "header" is often used to denote a relatively short bending member, and shear connection angles don't fall in that category.

 

[ajk1]

ok, thanks.

My experience is similar to that of hokie66...not familiar with the term, likely limited to Canada.
In my practice, I've referred to such angles installed vertically on the column as "clip angles" and those installed horizontally on the column as "seats or angle seats" (though more properly, they are "beam seats fabricated from angle"!).

 

[ajk1]

ok, I concede. I won't use the term anymore.

I like to think "header angles" is an old Canadian steelworker term, as in, "Hey Bob, watch yerslef on dat der angle, sure would be a bad header, eh?"
