abstract = {Rational yet simple and fast evaluation methods are needed to assess the seismic behavior of existing buildings. This is particularly important for post-disaster buildings such as emergency shelters and hospitals, for evaluations before or after an earthquake event. Current guidelines available in Canada (NRC 92) or United States (FEMA 154) propose rapid visual screening methods for this purpose. However, a more reliable method that could quantify structural seismic demand parameters and provide a better assessment of building performance is still needed. In this research, a 3-dimensional simplified assessment method is proposed for post-disaster buildings. The method is based on in situ building data collected from inspection, information on site conditions, and ambient vibration measurements (AVM). The proposed assessment method can be employed for the evaluation of seismic demand parameters such as relative floor displacements; story drift ratios, floor absolute accelerations and story shear forces. Another research project is being conducted in parallel which is aimed at evaluating the seismic performance of Operational and Functional Components (OFCs) (also called nonstructural components) of buildings. This matter is of high importance since OFC failure or malfunction can cause life safety hazards and significantly impact building functionality, and damage to property even if the structural system has performed satisfactorily during the earthquake. In this project, an inclusive database of buildings in which AVM were performed was collected. Using the aforementioned procedure, floor response-histories are derived for selected levels of the buildings and then considered as base excitation for OFCs to generate the corresponding floor response spectra (FRS). These experimental FRS are then used for seismic response evaluation of OFCs, with due consideration of dynamic interaction between the primary and secondary systems. The second objective of the research is to compare the derived FRSs with the corresponding Design Uniform Hazard Spectrum (UHS) recommended in the National Building Code of Canada (NBCC 2010) and develop a mathematical model to generate FRSs directly from the UHS taking into consideration the effect of different types of seismic force resisting systems, building height, soil conditions, location of the OFCs in the building, OFC/building period ratio, and estimated damping. The oral presentation will also include a detailed case study to illustrate the proposed procedures.<br/>},
