anchoring to reinforced concrete
(OP)
Hi,
I need to anchor pinned supports for steel beam (by double angles) to a reinforced concrete which has a lot of rebar, according to planes i have about 4 inch betweens rebar to place the anchors. But i don't know where the rebar are placed and i have some doubts.
I don't think it'll be correct to place a second column of holes in the angles (in order to find a place to hold the anchors) because it might change the force distribution in the deformation behaviour of double angles. It will be difficult to me to asses the resistance if an anchor needs to be placed at the second column of holes.
Another idea will be to make differents angles so i can switch the angle if needed. I just have 3 beams to be supported.
I don't know nothing about melting the anchors to rebars, some guide could help.
according to your experiences, How straight rebar remains after concrete is set?
Can give me some others ideas?

RE: anchoring to reinforced concrete
Not sure what you mean by "melting the anchors to rebars". You don't. You can get epoxied anchor bolts, etc.
They may be ways via ultrasound, etc. to locate the rebar.

The are chemical ways to weld the rebars.

If they had placed studs before the pour they could have welded or mechanically interlocked them in.
