Seismic assessment of masonry structures by means of code-based selected records
| Resumo: | Through the centuries, earthquakes represent one of the main causes of damage and loss of cultural heritage, monumental buildings, and historic centres, affecting the development of many countries worldwide. These kinds of constructions are usually constituted by structural masonry and have shown evidence of good behaviour under vertical static loads, however, given the mechanical properties of this heterogeneous material, such as the high specific mass, low tensile/shear strength, and reduced ductility, makes its use unsuitable in seismic prone areas. This paper conducts a comprehensive study regarding the seismic assessment of an existing masonry structure, using various sets of ground motions selected and fitted to the target elastic response spectrum according to the Eurocode 8 provisions. A comparison between the fitted response spectrum in the period range of 0.2T1-2T1 and in the full period domains is performed. |
