RISHybrid Simulation Testbed for Experimental Validation and Characterization of NDE and Sensor Technology
Publisher: American Society of Civil Engineers
Abstract: An increasing number of online structural health monitoring systems have been implemented on bridges, which are often comprised of a variety of local sensing and nondestructive evaluation (NDE) devices. However, before any ...
Long-Term Evaluation of Cold-in-Place Recycling and Factors Influencing Performance
Publisher: American Society of Civil Engineers
Abstract: Cold in-place recycling (CIR) is a type of rehabilitation strategy that has shown to significantly improve the condition of flexible pavements with adequate subgrade support. The process involves milling the distressed ...
Multiyield-Surface Implementation of a Simplified Three-Dimensional Hoek–Brown Strength Criterion
Publisher: ASCE
Abstract: This work presents the implementation of a simplified three-dimensional Hoek–Brown strength criterion using a multiyield-surface plasticity approach. The adopted three-dimensional simplification of the strength criterion ...
Critical Water Velocity for Snail Habitats in Canals
Publisher: American Society of Civil Engineers
Abstract: A design velocity was determined to prevent disease-bearing snails from inhabiting irrigation canals. In tropical irrigation systems many people in the argicultural community are infected with a parasitic disease spread ...
Contraction Analysis of Multi-Agent Control for Guaranteed Capture of a Faster Evader1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a verifiable condition for the selection of a sufficient number of pursuers to capture a faster evader. The condition is based on the tracking performance of a multi-agent control scheme. Trajectory ...
Nonlinear Inelastic-Degrading Structural Modeling Approach to Assess the Seismic Soil–Structure Interaction Response of Tall Buildings
Publisher: ASCE
Abstract: Oversimplifying structural modeling in the analysis of the seismic performance of tall buildings introduces variability and biases in the computed seismic response. Engineering demand parameters (EDPs) from coupled ...
Modeling Nonlinear-Inelastic Seismic Response of Tall Buildings with Soil–Structure Interaction
Publisher: ASCE
Abstract: Soil-structure interaction (SSI) effects are of interest for the seismic analysis and the design of tall buildings on shallow foundations, particularly when both the structure and soil undergo inelastic demands. The objective ...
Centrifuge and Large-Scale Modeling of Seismic Pore Pressures in Sands: Cyclic Strain Interpretation
Publisher: American Society of Civil Engineers
Abstract: Centrifuge modeling of pore pressure buildup in a sand deposit as a result of shaking is evaluated by comparison with a large-scale experiment. In large-scale Test SG-1, a 5.6-m-thick, mildly sloping deposit of hydraulic ...
An Analysis of the Quenching Performance of a Copper Nanofluid Prepared Using Laser Ablation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The quenching performance of a copper nanofluid (copper nanoparticles in deionized water), prepared using laser ablation, is compared to deionized water in both the still and agitated state. The nanoparticles significantly ...
Factors Affecting Binder Properties between Production and Construction
Publisher: American Society of Civil Engineers
Abstract: The majority of U.S. departments of transportation (DOT) maintain quality assurance (QA) programs that require asphalt binder testing to verify grade compliance according to Superpave performance grade (PG) specifications. ...
