【 摘 要 】

A wooden bell tower, erected in the 16th century, was vertically deflected due to uneven settlement of the subgrade having insufficient load-bearing capacity. The structure's condition was continuously deteriorating due to the advancing structural deformation. Structure renovation was designed and carried out in two phases. Foundations in the form of piles and strips were executed under the existing structure in the first phase, and then the structure was reinforced and straightened with twelve hydraulic jacks. The damaged above-ground components of the construction and its sheathing were replaced in the second phase. With the designed and executed procedure, it was possible to preserve the historical building in the unaltered form without interfering with the elements of the 500 hundred-years-old structure's construction. Force values and jacks' displacements were measured during straightening. The construction's behaviour, when eliminating the deflection, was described with the measurement forces in jacks and its displacement.
