Abstract:
Presents the procedure followed for the assessment of the structural condition of a reinforced concrete water tower 39.45 m high, with a reservoir capacity of about 400 m3, built in 1930 at Larissa, Greece. The water tower was built in an area of high seismicity and has been since then in continuous operation up to now. However, the structure presents serious symptoms of degradation due partly to past earthquake damages and mainly to the corrosion of the reinforcement which has led to extensive concrete cracking and spalling. So, an investigation was decided upon, aiming at the evaluation of the existing residual structural capacity and at the decision-making on probable intervention for the upgrading of the structure. In this paper, the in situ measurements and investigations, the laboratory tests, and the analytical computations carried out so far for the assessment of the structural condition of the tower, together with the results and the conclusions of this research, are presented in short.
