This project’s aim is not only to study the bearing capacity of a multi-storey reinforced concrete hotel, but also to study its strengthening. The hotel constructed in 1967 in Greece in seismic zone 2 area (Z2, a_GR/g=0.24) under the provision of the national codes of Members of Reinforced Concrete (1954) and of the Design Code for Earthquake Resistant structures (1959). It is a 5-storey reinforced concrete building with underground floor, ground floor (two levels), mezzanine floor, approachable and non approachable roof. Its overall high is 27.53m, including the non approachable roof, while the typical high of floors is 3.2m. SAP2000 is used for the analyses of the building. Modal response spectrum analysis, nonlinear static (pushover) analyses and nonlinear dynamic time-history analyses are performed. Three pairs of acceleration time histories are used. They are the earthquakes events of Corinth (1981, magnitude: 6.6), Kalamata (1986, magnitude 6.2) and L’Aquila-Italy (2009 magnitude: 6.3). The acceleration time-histories are obtained by the PEER Ground Motion Data Base-Beta version. The acceleration time-histories are scaled. The assessment of the bearing capacity shows that the structure requires rehabilitation. The rehabilitation aim is to reach the life safety performance level. Nonlinear static (pushover) analyses and nonlinear dynamic time-history analyses are performed to the retrofitted structure, showing that the target-performance level is succeeded, when seismic action corresponding to seismic return period of 475 years, or the scaled L’Aquila, Corinth, Kalamata acceleration time-histories are imposed to the structure.
