The paper shows a methodology that can be applied to assess the seismic vulnerability of regular and tall masonry towers. The methodology may be summarized as the following sequence of steps: 1) Preliminary numerical model of the structure; 2) Environmental vibration test and elaboration of the recorded signal; 3) Dynamic identification of the structure and of the basic dynamic parameters; 4) Non linear pushover analysis on the final identified model. This approach seems effective in giving reliable results on the ultimate resistance of the masonry structures, since most of the time the irregularities in the material cannot lead to a single value of elastic modulus valid all over the structure.

Abstract
The paper shows a methodology that can be applied to assess the seismic vulnerability of regular and tall masonry towers. The methodology may be summarized as the following sequence of steps: 1) Preliminary numerical model of the structure; 2) Environmental vibration test and elaboration of the recorded signal; 3) Dynamic identification of the structure and of the basic dynamic parameters; 4) Non linear pushover analysis on the final identified model. This approach seems effective in giving reliable results on the ultimate resistance of the masonry structures, since most of the time the irregularities in the material cannot lead to a single value of elastic modulus valid all over the structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
