Impact of complex system behavior on seismic assessment of RC bridges
… in experimental testing or calibrated numerical analyses due to assumptions made in test set-up, modeling simplifications, and disregard of system-level interaction. Nonlinear time-history analyses are performed on a set of bridge models subjected to a suite of carefully selected seismic records. …

Seismic Performance Comparison of a Fixed-Base Versus a Base-Isolated Office Building
… analysis in ETABS. In the analysis phase, nonlinear time history analyses at DBE and MCE levels are conducted in PERFORM-3D to obtain the related floor accelerations and interstory drifts. Finally, in the performance assessment phase, probable damage costs are computed using fragility …

Deep learning-based surrogate models for post-earthquake damage assessment
… classes on targeted structures are determined by nonlinear time history analyses. The development of various surrogate models is progressed in four phases. In Phase I, the multilayer perceptron (MLP) is used to develop multivariate seismic classifiers with up to 50 hand-crafted intensity measures …

Nonlinear Finite Element Modelling of Reinforced Concrete Frames Retrofitted with Shape Memory Alloy Buckling Restrained Braces
… located in high seismic zones. Furthermore, nonlinear time-history analyses are conducted. Earthquake records that simulate design earthquakes for the cities of Montreal and Vancouver were selected for the dynamic loading. At the end of the thesis, an optimized BRB design is provided in which …

Informing Code-Compliant Site-Specific Infrastructure Seismic Evaluations With Physics-Based Simulated Ground Motions
… and scaled to a target spectrum for performing nonlinear time-history analyses. Suitable sets of ground-motion records shall be selected by appropriately considering the earthquake parameters controlling the hazard at the site, including magnitude, fault distance, tectonic regime, and impulsive …

Next generation seismic fragility curves for california bridges incorporating the evolution in seismic design philosophy
… Parameterized high-fidelity three-dimensional nonlinear analytical models are developed for the portfolios of bridge classes within different design eras. These models incorporate a wide range of geometric and material uncertainties, and their responses are characterized under seismic loadings. …

Seismic Response of Short Period Structures and the Development of a Self-Centering Truss Moment Frame with Energy Dissipating Elements for Improved Performance
… includes a set of preliminary monotonic pushover analyses and nonlinear time history analyses to confirm the expected behavior of the system. Next, a mechanics investigation was undertaken where static pushover analyses (monotonic and cyclic) were used to help derive equations to predict system …
