ACI detailing of columns
ACI detailing of columns
(OP)
dear engineers
i have a question about the following paragraphs taken from ACI 318
10.7.4 Offset bent longitudinal reinforcement
10.7.4.1 The slope of the inclined portion of an offset
bent longitudinal bar relative to the longitudinal axis of the
column shall not exceed 1 in 6. Portions of bar above and
below an offset shall be parallel to axis of column.
10.7.4.2 If the column face is offset 3 in. or more, longitudinal
bars shall not be offset bent and separate dowels,lap spliced with the longitudinal bars adjacent to the offset
column faces, shall be provided.
what is cause for the 10.7.4.2? what will happen if the offset is about 4 in and i offset bent the long. bar with condition of maintaining the required slope of 1h:6v ???????????
if i have a beam with depth of 600mm adjecant to the column face that will be offset b 4 in can i offset the bar or have i to terminate it and provide a new dowel ??????
thanks

You have it backwards. If the sides are offset 3" or more, you cannot use 1:6 sloped bars.
I am not sure about the condition described in the OP's question. Perhaps he can provide a detail.

What is the name of this document/book to get it?
Or can you send it to download??

The text layers have -txti and -txtm for imperial and metric. Feel free to use, but, check first...

I'll drink to that... come to think of it, I'll drink to nearly anything.
Any improvements or corrections would be appreciated.

RE: ACI detailing of columns
i have attached a pdf with 4 details of columns to explain my first statements in my first post to clear what i want to say and understand
i want to know what are the right and wrong ones ( i recommend detail 2 and 4 to match the ACI318 statement that if i understand it right)
thanks
