RISDynamic Network Flow Model for Power Grid Systemic Risk Assessment and Resilience Enhancement
Publisher: ASCE
Abstract: Power infrastructure networks are susceptible to performance disruptions induced by natural or anthropogenic hazard events. For example, extreme weather events or cyberattacks can disrupt the functionality of multiple ...
Rocking Response of Unanchored Building Contents Considering Horizontal and Vertical Excitation
Publisher: ASCE
Abstract: The seismic performance of unanchored slender contents at various floor levels within a building has received little attention in the literature, despite earthquake reconnaissance reports routinely emphasizing the overturning ...
Development of Design Code Oriented Formulas for Elastomeric Bearings Including Bulk Compressibility and Reinforcement Extensibility
Publisher: American Society of Civil Engineers
Abstract: The introduction of alternative reinforcement types for elastomeric bearings has rendered it necessary to consider the extensibility of the reinforcement as an additional design parameter. The extensibility of the reinforcement ...
Out-of-Plane Behavior of Lightweight Metallic Sandwich Panels

Performance Enhancement of Steel Columns Using Concrete-Filled Composite Jackets
Publisher: American Society of Civil Engineers
Abstract: This paper studies the cross-sectional behavior of steel columns strengthened with fiber-reinforced polymers (FRPs). The composite column is constructed by wrapping the steel I-section column with epoxy-saturated glass- ...
Simplified Approximations for Critical Design Parameters of Rectangular Fiber-Reinforced Elastomeric Isolators
Publisher: American Society of Civil Engineers
Abstract: Analytical solutions for critical design properties of elastomeric bearings, such as the compression modulus, bending modulus, and maximum shear strain due to compression or rotation, including the compressibility of the ...
Shear Strain Demands in Elastomeric Bearings Subjected to Rotation
Publisher: American Society of Civil Engineers
Abstract: In seismic base isolation applications, fiber reinforcement was initially proposed as a potential cost-saving alternative to conventional steel reinforcement in laminated bearings. Steel reinforcement is often assumed to ...
Lateral Response Evaluation of Fiber-Reinforced Neoprene Seismic Isolators Utilized in an Unbonded Application
Publisher: American Society of Civil Engineers
Abstract: This study examines the experimentally obtained lateral response characteristics of model scale square fiber-reinforced elastomeric isolator (FREI) bearings, which are intended to mitigate seismic induced forces on ordinary ...
Seismic Fragility Evaluation of Lightly Reinforced Concrete-Block Shear Walls for Probabilistic Risk Assessment
Publisher: American Society of Civil Engineers
Abstract: With the North American seismic codes moving toward adopting performance-based seismic design (PBSD) approaches, there is a need to develop seismic probabilistic risk assessment (PRA) tools for different construction ...
Seismic Isolation of a Shear Wall Structure Using Rectangular Fiber-Reinforced Elastomeric Isolators
Publisher: American Society of Civil Engineers
Abstract: The seismic response of a 2-story reinforced concrete shear wall structure seismically isolated using unbonded rectangular fiber-reinforced elastomeric isolators (FREIs) is investigated. Using rectangular isolators, rather ...
