Li, Yong; Astroza, Rodrigo; Conte, Joel P.; Soto Muñoz, Pedro (Wiley, 2017)Nonlinear finite element (FE) modeling has been widely used to investigate the effects of seismic isolation on the response of bridges to earthquakes. However, most FE models of seismic isolated bridges (SIB) have used ...

Li, Yong; Astroza, Rodrigo; Conte, Joel P.; Soto Muñoz, Pedro (Elsevier, 2017)In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...

Astroza, Rodrigo; Pastén Puchi, César; Ochoa Cornejo, Felipe Agustín (Elsevier, 2017)Site response analysis is crucial to define the seismic hazard and distribution of damage during earthquakes. The equivalent-linear (EQL) is a numerical method widely investigated and used for site response analysis. ...

Astroza, Rodrigo; Gutiérrez, Gonzalo; Repenning, Christian; Hernández, Francisco (Earthquake Engineering Research Institute, 2018)This paper presents the identification of the instantaneous modal properties and the experimental response of a full-scale, five-story base-isolated RC building tested on a shake table. A suite of earthquake motions of ...

Mercado, Vicente; Ochoa-Cornejo, Felipe; Astroza, Rodrigo; El-Sekelly, Waleed; Abdoun, Tarek; Pastén, Cesar; Hernández, Francisco (Elsevier Ltd, 2019)This paper combines data from laboratory, centrifuge testing, and numerical tools to highlight the predictive capabilities of the Bayesian method for uncertainty quantification and propagation. The Bayesian approach is ...
