heal.abstract	A range of seismic assessment methods is employed to evaluate the seismic behavior of a newly constructed building and to estimate its seismic losses. For this scope, a 7-story building with a basement constructed in Kallithea, Greece in 2022 was studied. In addition, we studied the seismic behavior of an added roof water tank, this being the typical practice for several areas outside of Athens with low or inadequate water pressure. As such non-structural components are rarely designed by structural engineers, the aim is to investigate whether there will be damage due to the (typically amplified) roof top acceleration. The Rapid Visual Inspection method was used in order to classify the building in a priority category for further checking. For the second level rapid seismic assessment, the methods proposed by Dritsos S., Vougioukas E. and the new FEMA P-2018 guidelines were applied. In addition, nonlinear static analyses were performed based on the Greek code (KANEPE), Eurocode 8-Part 3, and ASCE/SEI 41-17. The Rapid Visual Inspection method revealed that the building belongs to the category with low priority for further checking, as expected of a newly designed structure. Regarding the results of the second level rapid seismic assessment methods and the nonlinear static analyses, considerable scatter is observed, with KANEPE being the most conservative approach. Furthermore, the analysis of the roof water tank showed that it failed at a peak ground acceleration PGA of 0.067g, or 40% of the design PGA, corresponding to an earthquake with a 35-year return period rather than the needed 475 years. Therefore, this water tank has a high probability of collapse during the lifetime of the building (50 years), potentially causing severe water damage to the roof, stairwell, and floor contents. Moreover, the fragility curves of the building were estimated using the SPO2FRAG software for both KANEPE and EC8, further showing the conservatism of KANEPE. Finally, the repair cost for various levels of building damage was estimated using the PACT software developed by FEMA P-58. The results showed that in all cases, the critical elements are generally the infills, the walls, and the roof water tank, although the average annual loss is low, reaching only 0.66% (KANEPE) to 0.16% (EC8) of the total building replacement cost.	en
