Strengthening and Retrotting of Structures using Post-installed Connections

Indian Association Of Structural Engineers (IAStructE)

ABOUT THIS CONFERENCE

As urban demands evolve, extension of the service life of existing buildings has become essential to balance growth with sustainability. This often requires strengthening structures affected by aging, change in functional needs, safety requirements, or design and construction deficiencies. Structural retrofitting improves performance, reduces downtime, conserves materials, and ensures public safety, using either global or local strengthening methods as needed. This lecture will cover common strengthening techniques include concrete jacketing with post-installed rebars, steel jacketing using post-installed anchors, and innovative shear-strengthening systems employing post-installed chemical anchors without base plates. Shear failure and punching shear failure are critical for concrete beams, slabs and foundations. This discussion will review the local strengthening techniques with postinstalled solutions, codal provisions for design, testing and installations and some real-time case studies demonstrating the application of this technology in existing structures...
