 The paper is focused on the analysis, redesign and rehabilitation solutions applied for old existing structures in seismic zones. The old malting building, erected between 1857-1876 at the “Timisoreana” Brewery, is a five storeys masonry structure and a tower composed of: walls of (140-50) cm thickness; inter-storey floors - brick masonry vaults supported by steel profiles; a tower, of about 14 m height and 2.80 m diameter, supported by an interior dome. The main structural damages were: vertical cracks in the tower masonry structure; corrosion of steel members – horizontal circular rings for confining the tower; steel profiles for supporting the floor masonry vaults. The static and dynamic analysis at different actions showed up major structural vulnerability, mainly due to the period of design and erection (19th century). In order to preserve the old building as architectural monument and to reduce the seismic failure risk, some strengthening solutions were designed and applied. The strengthening solutions were selected in order to obtain technical and economical advantages: safe behaviour at seismic actions; slight change of overall structural stiffness; easy strengthening technology and short refurbishment period; low rehabilitation cost.
