Aim of thesis
´The aim of this bachelor thesis is to perform a seismic analysis of an historical masonry building
located in seismic zone based on Italian code NTC 2008 and investigate the possible retrofitting
techniques in order to preserve the building in case of earthquake. Elective method will be applied
on chosen structure and in case of unsatisfactory results would be the structure retrofitted.

Study case – „Palizzi“ castle
´Adress: Via Sant´Angelo, 14 Regio Calabria (RC) Palizzi, 89038, Italy
´Name of building: „Palizzi“ castle
´Permanent parcel: st. 113, 114
´Building use: Historical monument
´Owner: Municipality of Palizzi

Thank you for your attention!
•I want to acknowledge “Studio KR e Associati” and “Studio Associato Amaddeo-Fiumanò” for providing
the blueprint and the design specification of the castle.

Questions from supervisor and oponent
´Existují i jiné možnosti úpravy historické konstrukce, tak aby vzdorovala seismickému zatížení?
Uveďte příklady které znáte. •Do another retrofitting methods for historical structures exist?
Please give examples. ´Jaký máte názor na zpevnění zdiva injektáží? Je vhodná pro zpevnění zdiva
při účincích seismického zatížení? •What is your opinion about strengthening masonry by injection
method? Can the method be applied for earthquake resistance? ´V jakém zdivu obecně lze injektáž
aplikovat a v jakém naopak ne? Co je rozhodující parametr? •In which type of masonry could be
possible to apply injection method and in which not? What is the critical parameter?
