RISParticle Size Effect on the Evolution of Stress and Fabric in Granular Materials under True Triaxial Conditions
Publisher: American Society of Civil Engineers
Abstract: Particle size significantly influences the macroscopic and microscopic responses of granular materials. The main purpose of previous works was to investigate the macroscopic response, but the influence of particle size on ...
Reliability Assessment of Concrete under Chloride Penetration and Fatigue Loading Based on Copula Function
Publisher: ASCE
Abstract: The reliability of concrete in complex environments is the basis for improving the reliability of concrete structures. A concrete reliability assessment based on multiple degradation factor is proposed. First, chloride ...
Fatigue Crack Assessment for Orthotropic Steel Deck Based on Compound Poisson Process
Publisher: ASCE
Abstract: This study presents a crack propagation stochastic process model for orthotropic steel deck (OSD) based on the structural health monitoring (SHM) data. An inhomogeneous compound Poisson process model, which is integrated ...
Optimization Framework to Assess the Demand Response Capacity of a Water Distribution System
Publisher: ASCE
Abstract: As large electricity consumers, water distribution system (WDS) pumping stations have the potential to become meaningful participants in demand response (DR) programs. The authors propose an optimization framework for ...
Thermal Consolidation of Saturated Silty Clay Considering Different Temperature Paths: Experimental Study and Constitutive Modeling
Publisher: ASCE
Abstract: Based on the self-developed axisymmetric test apparatus for hollow cylinder specimens, an experimental study on the thermal consolidation behavior of saturated silty clay with different overconsolidation ratios under ...
Physics-Informed Deep Learning for Computational Elastodynamics without Labeled Data
Publisher: ASCE
Abstract: Numerical methods such as finite element have been flourishing in the past decades for modeling solid mechanics problems via solving governing partial differential equations (PDEs). A salient aspect that distinguishes these ...
Climate Change and Homicide: Global Analysis of the Moderating Role of Information and Communication Technology
Publisher: American Meteorological Society
Abstract: The link between climate change and human conflict has received substantial attention in academic research using different measures of “conflict”; however, it is yet to interpret interpersonal violence in terms of homicide. ...
Effect of Particle Shape on Contact Network and Shear-Induced Anisotropy of Granular Assemblies: A DEM Perspective
Publisher: ASCE
Abstract: The particle shape plays an important role in the macroscopic response of granular materials. Based on discrete element method (DEM) simulation results of triaxial tests on samples with different particle shapes, this study ...
Exploring the Determinants of Travel-Related CO2 Emissions Considering Spatial Heterogeneity
Publisher: American Society of Civil Engineers
Abstract: Urban transportation significantly contributes to greenhouse gas emissions, with CO2 emissions from urban travelers varying across different regions. Identifying the determinants of residents’ travel-related CO2 emissions ...
Three-Dimensional Discrete-Element Modeling of Geocell-Reinforced Ballast Considering Breakage
Publisher: ASCE
Abstract: This paper presents a three-dimensional discrete-element method (DEM) study examining the settlement and breakage behavior of geocell-reinforced ballast. The reinforced ballast chamber reproduced the geocell in configuration ...
