Concrete Beam Repair
Concrete Beam Repair
(OP)
Hi,
I'm reviewing a concrete beam in a building under construction which was loaded accidentally from a falling object. Some diagonal shear cracks have formed near the supports on both faces. There are no flexural cracks so I'm thinking that the bars have not yielded and are probably still ok. Since we are still in the construction stage of the project, I recommended demolishing the beam and reconstructing. The project manager wants me to review other options including epoxy injection since the the location of this beam and the time it would take would hold back other works. I'm a bit weary about this this option. Are there other suitable options or should I press the issue of demolition.
Thanks

I'm not sure I'd be too quick to demolish. If you could get the concrete out of there and leave the original bars, that would be great, but that's kind of tricky.

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.
