The paper presents a critical analysis of the structural response and the level of damage of a historic tower of Santo Stefano of Sessanio that was hit by the main L' Aquila earthquake of April 2009. A FE model was constructed to simulate the structural behaviour during the seismic event. The presence of a reinforced concrete slab in the upper part of the tower probably cause a different dynamic behavior compared with the lower masonry circular walls. Have also been investigated boundary conditions at the base, the different mechanical property of masonry and the contribution of the stiffness of the wooden floors. © (2014) Trans Tech Publications, Switzerland.

Abstract
The paper presents a critical analysis of the structural response and the level of damage of a historic tower of Santo Stefano of Sessanio that was hit by the main L' Aquila earthquake of April 2009. A FE model was constructed to simulate the structural behaviour during the seismic event. The presence of a reinforced concrete slab in the upper part of the tower probably cause a different dynamic behavior compared with the lower masonry circular walls. Have also been investigated boundary conditions at the base, the different mechanical property of masonry and the contribution of the stiffness of the wooden floors. © (2014) Trans Tech Publications, Switzerland.
