Trying to get an idea of what can be done to fix shear cracks in existing beams.
This request has come through on a 40 year old structure, but I'm not sure yet if this is was due to lack of stirrup detailing, insufficient grade beam design, or the incorrect placement of a piles support.
1. If the analysis AND field investigation proves that sufficient stirrups were used and cracks still occurred, what is the protocol?
2. If the analysis OR field investigation proves an insufficient design, detailing, or construction, can we remove existing concrete to expose longitudinal bars and wrap new stirrups?
