Anchorage decisions often determine whether a repair detail is practical, code-compliant, and capable of transferring load into existing concrete. Presented with Luis R. Pelayo, PE, SE, this session connects code and qualification requirements to the realities of existing members: uncertain geometry, reinforcement congestion, edge distance, concrete condition, installation access, and temporary loading. The case studies show how those constraints shape partial-depth repairs, section enlargement, and full replacement.
Key ideas
- Anchor capacity depends on the volume and condition of concrete engaged, not the steel component alone.
- Going deeper or adding more anchors does not automatically produce a better detail.
- Existing geometry, reinforcement, loads, installation access, and temporary conditions must be understood early.
- Code requirements, evaluation reports, testing, constructability, and repair sequencing need to work as one design system.
