| Summary: |
| Repair of reinforced concrete structures is usually caused by changes in
stress patterns or by reduced amount of reinforcement in the structural elements, due to
the effect of corrosion. This is a reason for detailed examination of the built materials
and analysis of loads and stress patterns. According to results decision was made on
the type and method of structural repair. Paper presents the modern methods for repair
of reinforced concrete structures. The first part describes how to repair using carbon
fibre bands and fabrics. Calculation for repair with carbon fibre was made in the
program S & P FRP Lamella, under the current regulations for the calculation of
carbon fibre EC2. Second part of the paper presents solution for reinforced concrete
ribbed ceiling repair Reparation have been carried out by implementing new composite
elements, for the most damaged parts of the ceiling and beams, as well as by applying
light-weight beams in every other field of of ceiling ribs for smaller cracks. Besides these
works also is presented reparation of minor damaged ribs adding a specially shaped
steel in order to form composite sistem with undamaged parts of ribs and poured
mixture as a epoxy- special mortars. |
