RISPostearthquake Vertical Load-Carrying Capacity of Extended Pile Shafts in Cohesionless Soils: Quasi-Static Test and Parametric Studies
Publisher: ASCE
Abstract: The belowground portion of extended pile-shaft-supported bridges is usually prone to earthquake-induced damage during earthquake shakings. The unobservable pile damage below the ground surface makes it difficult and ...
Ductile Behavior of Scoured RC Pile-Group Foundations for Bridges in Cohesionless Soils: Parametric Incremental Dynamic Analysis
Publisher: ASCE
Abstract: Scoured pile-group foundations (SPGFs) are susceptible to inelastic deformation during earthquakes. Hence, the ductile behavior of SPGFs has become a rising concern in academic and industrial communities. Traditionally, ...
Seismic Behavior of Pile-Group-Supported Bridges in Liquefiable Soils with Crusts Subjected to Potential Scour: Insights from Shake-Table Tests
Publisher: ASCE
Abstract: One-g shake-table tests were conducted to characterize seismic demands and reveal failure mechanisms of pile-supported bridges in liquefiable soils with crusts subjected to different scour scenarios, namely no scour, partial ...
Pile Group Effect Modeling and Parametric Sensitivity Analysis of Scoured Pile Group Bridge Foundations in Sandy Soils under Lateral Loads
Publisher: ASCE
Abstract: Scour can increase the earthquake-induced damage in pile group foundations. Quantifying the parameter sensitivity of the seismic performance for scoured pile group foundations is essential for the optimal design and retrofit ...
Quantifying Easy-to-Repair Displacement Ductility and Lateral Strength of Scoured Bridge Pile Group Foundations in Cohesionless Soils: A Classification–Regression Combination Surrogate Model
Publisher: ASCE
Abstract: Scoured pile-group foundations in bridges are likely to undergo inelastic deformation during earthquakes, which can be utilized to dissipate seismic energy and withstand seismic loads by the post-yield hardening strength ...
Probabilistic Postearthquake Vertical Load-Carrying Capacity Loss Model and Rapid Functionality Assessment for Reinforced Concrete Circular Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: The rapid and accurate postearthquake traffic capacity or functionality loss assessment for highway bridges after a strong earthquake is crucial to the decision-making for postearthquake emergency rescue and recovery, as ...
Efficient Finite-Element Model for Seismic Response Estimation of Piles and Soils in Liquefied and Laterally Spreading Ground Considering Shear Localization
Publisher: American Society of Civil Engineers
Optimal Force-Based Beam-Column Element Size for Reinforced-Concrete Piles in Bridges
Publisher: American Society of Civil Engineers
Abstract: The nonobjective disadvantages of the force-based frame element, such as the nonobjective curvature prediction, have been discussed by many researchers. The trial-and-error method is commonly used to determine element size, ...
Parametric Pushover Analysis on Elevated RC Pile-Cap Foundations for Bridges in Cohesionless Soils
Publisher: American Society of Civil Engineers
Abstract: For bridges under seismic excitations, current design practices recommend to comply with the capacity protection principle for pile foundations. However, in cases, such as elevated (or scoured) RC pile-cap foundation ...
