Nonlinear static procedures (NSPs) are widely used for the seismic displacement prediction of existing buildings. These procedures have become increasingly important with the emergence of performance-based engineering as a technique for seismic evaluation and design where the expected performance is better correlated to displacement response. This paper presents an evaluation study of current NSPs for seismic performance assessment of masonry buildings. The evaluation is conducted through comparison of displacement predictions from current NSPs with the values recorded from shake table tests of a masonry building model. The investigated NSPs are: the improved Displacement Coefficient Method (DCM) defined in FEMA440 and implemented in the ASCE-41 and the improved Capacity Spectrum Method defined in FEMA-440. The predicted displacements are used for probabilistic damage assessment using fragility curves that describes the probability of being or exceeding a specific damage state given displacement response. The results showed that NSPs predicted high probability of extensive damage state which is in good agreement with the observed damage from testing. This paper also presents a discussion of the sources of variability in the predicted displacement and damage prediction using the investigated NSPs and emphasis the importance of the consideration of uncertainties in seismic performance assessment using fragility curves.
