Do-Eun Choe, Auteur ; Paolo Gardoni, Auteur ; David Rosowsky, Auteur |Reinforced concrete (RC) columns are the most critical components in bridges under seismic excitation. In this paper, a simple closed-form formulation to estimate the fragility of RC columns is developed. The formulation is used to estimate the [...]

Do-Eun Choe, Auteur ; Paolo Gardoni, Auteur ; David Rosowsky, Auteur |The increased deformation and shear fragilities of corroding RC bridge columns subject to seismic excitations are modeled as functions of time using fragility increment functions. These functions can be applied to various environmental and mater[...]

Ramesh Kumar, Auteur ; Paolo Gardoni, Auteur |Current seismic design of bridges is based on “one-time” performance of the bridges during the design seismic event. However, there might be a considerable probability of observing more than one damaging earthquakes in a bridge’s service life. B[...]

Qindan Huang, Auteur ; Paolo Gardoni, Auteur ; Stefan Hurlebaus, Auteur |Knowing the ability of reinforced concrete (RC) bridges to withstand future seismic demands during their life-cycle can help bridge owners make rational decisions regarding optimal allocation of resources for maintenance, repair, and/or rehabili[...]

Vahid Bisadi, Auteur ; Paolo Gardoni, Auteur ; Monique Head, Auteur |Using steel pedestals has become an effective method for elevating simply supported bridges in the United States. However, a method is needed to estimate their lateral load capacity and probability of failure subjected to different levels of app[...]

Paolo Gardoni, Auteur ; Pillai, Radhakrishna G., Auteur ; Hueste, Mary Beth D., Auteur |The presence of air voids, moisture, and chlorides inside tendons or ducts was cited as a reason for the early age strand corrosion and failure in the Mid-bay, Sunshine Skyway, and Niles Channel posttensioned (PT) bridges in Florida, United Stat[...]

Paolo Gardoni, Auteur ; David Trejo, Auteur ; Marina Vannucci, Auteur |Current models of the modulus of elasticity, E, of concrete recommended by the American Concrete Institute and the American Association of State Highway and Transportation Officials are derived for normally vibrated concrete (NVC). Because self-[...]

Jinquan Zhong, Auteur ; Paolo Gardoni, Auteur ; David Rosowsky, Auteur |Probabilistic models are developed to predict the deformation and shear demands due to seismic excitation on reinforced concrete (RC) columns in bridges with two-column bents. A Bayesian methodology is used to develop the models. The models are [...]

Qindan Huang, Auteur ; Paolo Gardoni, Auteur ; Stefan Hurlebaus, Auteur |In performance-based seismic design, general and practical seismic demand models of structures are essential. This paper proposes a general methodology to construct probabilistic demand models for reinforced concrete (RC) highway bridges with on[...]

Laura C. Bolduc, Auteur ; Paolo Gardoni, Auteur ; Jean-Louis Briaud, Auteur |Scour at a bridge pier is the formation of a hole around the pier due to the erosion of soil by flowing water; this hole in the soil reduces the carrying capacity of the foundation and the pier. Excessive scour can cause a bridge pier to fail wi[...]

Jessica Simon, Auteur ; Joseph M. Bracci, Auteur ; Paolo Gardoni, Auteur |One of the greatest challenges in the United States today is overcoming the deterioration of an aging infrastructure system. In particular, the highway/bridge infrastructure system has traditionally been neglected of maintenance and repair. One [...]

Jinquan Zhong, Auteur ; Paolo Gardoni, Auteur ; David Rosowsky, Auteur |Corrosion-induced cracks in reinforced concrete (RC) structures degrade the stiffness of the cover concrete. The stiffness degradation is mainly caused by the softening in the stress-strain relation in the cracked concrete. Limited efforts have [...]
