reinforcement: column-beam or wall-slap
reinforcement: column-beam or wall-slap
(OP)
Hi Struct.Eng's
There are three different or maybe even more possibilitys how to connect the beam reinforcment to a edge column or the slab reinforcment to the concrete retaining wall.
Have a look on the attached sketch. Me personal I like the left solution because it is easy to manage on site. The column or wall can be concreted to the top and then later the connection reinforcement "U bar" will be placed.
BUT: Is this type of detail not weaker then the middle one or the right one? Does it not give a better connection if the L-bars are casted INTO the column or wall?

With two layers of bar I would do something like this: (diagonals are optional - this was a tall tank wall)

Of course it is a detail which does not transfer moments. Is actually a kind of a pinned support

However, there is generally no reason for the 90 degree cogs to go below the construction joint. Either lean them over or use 180 degree hooks within the slab or beam depth.

Ok by beams and columns maybe it is better rather to go for the 90degrees L' shape bars which are cast into the column
Now I found even some reports in the internet with even more solutions uuhh now am even more confuse what is the best, easiest and strongest connection
