Retrofit Opening in Tilt-Up Wall Panel
Retrofit Opening in Tilt-Up Wall Panel
(OP)
Does any one have a good reference for evaluating retrofit openings in existing tilt-up concrete walls? We have shop drawing of the existing panel, know the reinforcement and spacing, concrete strength, etc. My concern is cracking at the corners of the new opening and what should/can be done for ensure serviceability of the existing panel.

As for the corner bars, although I do not believe the article and still use them regardless, there was an article a few years ago espousing the fact that they were not needed. The choice is yours. However, I never use them in a retrofit siuation, only new construction. In that fact may be your answer.
