Abstract


Storey extensions are an increasingly popular way to crowded cities. Lack experience and knowledge concerning strengthening of structures are major challenges for engineers. This paper presents strengthening practice adopted for foundations of existing building when storey extension is needed. Literature concerning strengthening techniques commonly adopted and some historical cases were reviewed. A complex hall building in university of Khartoum which was rehabilitated in 2009 by strengthening the structural members of the existing building to accommodate additional floors was undertaken as a case study. The records and reports of the original design and last rehabilitation of the building were reviewed. Field inspection of the building condition before rehabilitation was carried out. The study results showed that the appropriate design, the strengthening materials used and the procedure followed are the key factors for economical and successful strengthening
