 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.
