| Abstract: |
The paper deals with the results and design recommendations obtained from an experimental programme and its application on a structural rehabilitation. The experimental programme presents the strengthening effect of RC columns by coating with new RC jacketing. Methods of increasing bond between old and new concrete are analysed: no bonding agent; surface chemical bonding agent; mechanical fixed connectors; chemical fixed connectors. The analysed strengthening solutions are applied on an existing four storeys RC framed structures built in 1940 and located in a seismic zone. The structure presents poor quality concrete, poor reinforcement detailing and weakness of reinforcement at present-day magnitude of seismic action. As the owner requirement was to build two more storeys, some rehabilitation solutions were adopted: RC jacketing of foundations and columns; CFRP jacketing of beams and slabs. |
