RISExperimental Study on Effects of Casting Procedures on Compressive Strength, Water Permeability, and Interfacial Transition Zone Porosity of Rock-Filled Concrete
Publisher: American Society of Civil Engineers
Performance of On-Site Earthquake Early Warning System Using Strong-Motion Records from Recent Earthquakes
Publisher: American Society of Civil Engineers
Abstract: The method of on-site earthquake early warning was proposed in the past decade to enhance seismic preparedness and safety measures for areas close to the earthquake epicenter. The method leverages critical information ...
Transient Analysis of Dam–Reservoir Interaction Using a High-Order Doubly Asymptotic Open Boundary
Publisher: American Society of Civil Engineers
Abstract: A high-order doubly asymptotic open boundary (DAOB) for the modeling of a semi-infinite reservoir with constant cross section is developed, in which the compressibility of water and the absorption characteristic of a ...
Mechanical Behavior of Cemented Granular Aggregates under Uniaxial Compression
Publisher: American Society of Civil Engineers
Abstract: Cemented granular aggregates composed of densely packed particles bound together by a matrix partially filling the interstitial pore space, connecting adjacent grains and forming cemented grain-to-grain contacts. The ...
Mechanical Behavior of Cemented Granular Aggregates under Uniaxial Compression
Publisher: American Society of Civil Engineers
Abstract: Cemented granular aggregates composed of densely packed particles bound together by a matrix partially filling the interstitial pore space, connecting adjacent grains and forming cemented grain-to-grain contacts. The ...
Effects of Strain History and Induced Anisotropy on Reliquefaction Resistance of Toyoura Sand
Publisher: ASCE
Abstract: Recent earthquake events have indicated that liquefaction histories can greatly affect the reliquefaction resistance of saturated sandy ground. This paper reports a fundamental experimental study of medium-dense/dense ...
Probing Fabric Evolution and Reliquefaction Resistance of Sands Using Discrete-Element Modeling
Publisher: ASCE
Abstract: Recent case histories have demonstrated that soil liquefaction can occur repeatedly at a site during a sequence of earthquake events. Field observations and laboratory tests imply that reliquefaction resistance can be ...
Discrete-Element Modeling of Cemented Granular Material Using Mixed-Mode Cohesive Zone Model
Publisher: ASCE
Abstract: This paper presents an energy-controlled fracture model to simulate mechanical behavior of cemented granular material (CGM). A modified mixed-mode cohesive zone model is developed to describe the damage behavior of the ...
An Air Stagnation Index to Qualify Extreme Haze Events in Northern China
Publisher: American Meteorological Society
Abstract: AbstractStagnation weather affects atmospheric diffusion ability, and hence causes the occurrence of haze events, which have been happening frequently in northern China (NC). This work puts forward an air stagnation index ...
Simulating the Regional Impacts of Urbanization and Anthropogenic Heat Release on Climate across China
Publisher: American Meteorological Society
Abstract: ogether with economic development and accelerated urbanization, the urban population in China has been increasing rapidly, and anthropogenic heat released by large-scale energy consumption in cities is expected to be a ...
