Loss assessment methodologies have been introduced to assess the seismic performance of buildings using more meaningful metrics like direct monetary losses. Different approaches exist, each with varying degrees of complexity and requiring different levels of detail, regarding structural behavior characterization or damage and loss estimation, for example. With these developments, loss assessment is increasingly becoming a more commonplace instrument in the seismic eva‎luation and retrofitting of existing buildings. Despite these developments, there is arguably still a need to provide practicing engineers with simplified tools with which to conduct building-specific loss assessment. Displacement-based methodologies have been developed over the past number of years with a particular focus on design. The extension of this approach to loss assessment via displacement-based assessment (DBA) is very necessary. In this article after introducing a structural typology as a case study that is used in Iranian school sport buildings, the method and parameters of structural modeling and analyzing in OpenSees is discussed and after driving analytical results post processing efforts is done. The structural loss curve with rigorous and simplified methods is driven and values of expected annual loss (EAL) are compared. The expected annual loss with rigorous method is equal to 0.05 percent of replacement cost that the simplified method gives 12 percent more than this value.
