Abstract (EN):
Purpose – When a numerous amount of buildings was built in reinforced concrete, in a period when
the regulations did not have the design philosophy for the occurrence of earthquakes, it is of extreme
importance to carry out full and effective structural assessments, specially considering and comparing
bare frame and infilled structure. The paper aims to discuss these issues.
Design/methodology/approach – Among several possibilities to make the evaluation as, simplified,
linear analysis and static non-linear analysis, the non-linear dynamic can provide the most accurate
numerical behaviour compared to the real one. The time-history non-linear analyses are developed on
the software SeismoStruct for different levels of intensity. Local verifications are then applied
separately from both Eurocode and Italian Code.
Findings – The application of validated models for the analysis of real buildings allows a complete
seismic assessment. The level of uncertainty increases integrating particularities regarding the infill
masonry walls. The paper shows important global and local seismic safety for these complex typology
of buildings.
Originality/value – A representative common concrete structure without seismic provisions is first
analysed and discussed in terms of global behaviour, deformations and progression of forces. The case
study structure is considered both as bare structure and with integrated infill panels. It is also
discussed in a local level, about brittle and ductile mechanisms, and extra comparisons between
different interpretations of different standards. The case study structure is considered both as bare
structure and with integrated infill panels.
