BIM-based Damage Estimation of Buildings under Earthquake Loading Condition

Abstract

In this study, it is tried to provide an estimation of damages imposed to a prototype office building as a result of earthquake occurrence. For this purpose, first a model is developed in BIM and then its properties are exported to a structural analysis software (opensees) in order to evaluate the structure's response under specific loading condition. Next, the outcome of opensees is used to identify the building's Damage State (DS). Then, the associated costs with each damage state are estimated by Performance Assessment Calculation Tool (PACT) provided by Federal Emergency Management Agency (FEMA). Finally, a Life Cycle Environmental Assessment is performed to identify the environmental impacts of the damages imposed to the building as a result of earthquake. For this purpose, embodied energy of the building is calculated and then based on the damage probability, the total embodied energy losses are calculated.
