Abstract
The structural reliability of the wooden tower of the Grote of St. BavoChurch in Haarlem has been assessed with the regular methods. In addition to the regular methods, some modern technologies have been used in the structural analysis. The mechanical properties of the timber have been determined with longitudinal vibration tests and visual grading. The inclination of the tower has been determined with a terrestrial laser scanner and the entire has been modeled and verified with a Finite Element Model. Conclusions are based on the results of the Finite Element Model, which takes the determined mechanical properties and inclination in consideration.
