High strength bars (Freyssibar bars)
are often used to introduce pre-stress into existing areas with high stress
concentrations or subject to bursting forces. This could include column
heads, bridge deck diaphragms, and anchorage regions. High strength bars
can provide a useful increase in load carrying capacity or act as a remedial
solution for existing over-stressed sections. High strength bars may also
be used as an alternative to plate bonding. Plate bonding Suitable for
under-strength beams and floor slabs. Steel plates of calculated length
and cross section are bolted and / or glued using epoxy adhesive to the
tension zone of the structural element. The increased depth composite section
enhances load carrying capacity.
