This study covers the seismic performance evaluation of an old template-reinforced concrete
building in Albania designed in 1982. This building category is constructed as residential
moment-frame with no shear walls. For the demand calculation, Incremental Dynamic
Analysis (IDA), is selected as a method that provides the response behavior of the structure
under a set of ground motion records from the elastic range until total collapse. More than
one thousand dynamic analyses are performed in the environment of ZeusNL software,
developed particularly for earthquake applications. A set of 18 ground motion records with
magnitude ranging from 6.5 until 7.1 is used to perform the analyses. Furthermore, IDA
curves are generated based on the values gathered from the intensity measure (IM) and
damage measure (DM) defined as 5% damped first mode spectral acceleration, Sa(T1,5%) and
maximum global drift ratio, ϴmax respectively. In addition, limit states are selected as
Immediate Occupancy (IO), Collapse Prevention (CP) and Global Instability (GI) based on FEMA
guidelines. Finally, the interpretation of the building performance is presented in terms of
IDA fractiles are summarized as 16%, 50% and 84%.
