RISUncertainty Analysis and Quantification in Flood Insurance Rate Maps Using Bayesian Model Averaging and Hierarchical BMA
Publisher: American Society of Civil Engineers
Abstract: Flood Insurance Rate Maps (FIRMs) managed by FEMA have been providing ongoing flood information to most communities in the United States over the past half-century. However, the uncertainty associated with the modeling of ...
Developing Customized NRCS Unit Hydrographs for Ungauged Watersheds in Indiana
Publisher: American Society of Civil Engineers
Abstract: The Natural Resources Conservation Service (NRCS, formerly the Soil Conservation Service, SCS) unit hydrograph (UH) is one of the most commonly used synthetic UH methods for hydrologic modeling and engineering design all ...
Electrokinetic Enhancement: Effect of Sample Stacking on Strengthening Heavy Metal Removal in Electrokinetic Remediation of Municipal Solid Waste Incineration Fly Ash
Publisher: American Society of Civil Engineers
Abstract: Municipal solid waste incineration (MSWI) fly ash is internationally categorized into a hazardous waste due to its high content of heavy metals (HMs) and dioxins. A traditional electrochemical platform was intrinsically ...
Effective Load Transfer Capacity Analysis for Asphalt Mixture Skeleton Based on Main Force Chain Characteristics and Discrete Element Method
Publisher: ASCE
Abstract: To clarify the effective load transfer capacity of asphalt mixture skeletons, granular material mechanics and the discrete-element method (DEM) were introduced to analyze the morphological characteristics of skeleton main ...
Cohesion Performance of Tack Coat Materials between Polyurethane Mixture and Asphalt Mixture
Publisher: ASCE
Abstract: A polyurethane (PU) mixture was used to replace the wearing course of asphalt pavement because of its excellent mechanical properties, which necessitated the selection of suitable interlayer bonding materials between the ...
Fatigue Deformation Model of Plain and Fiber-Reinforced Concrete Based on Weibull Function
Publisher: American Society of Civil Engineers
Abstract: A novel model based on the three-parameter Weibull function is proposed to describe the three-stage fatigue deformation behavior of plain and fiber-reinforced concrete. The fatigue strain at a particular stress between ...
Algorithms for Generating Air-Void Structures of Idealized Asphalt Mixture Based on Three-Dimensional Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: The air-void structure of an asphalt mixture is a very important feature because it significantly impacts the strength and modulus of the material. Consequently, in-depth research into an air-void structure for quantification ...
Flexural Performance of UHPC–Concrete–ECC Composite Member Reinforced with Perforated Steel Plates
Publisher: ASCE
Abstract: A novel reinforced concrete structural member comprising ultrahigh-performance concrete (UHPC) and engineered cementitious composite (ECC) was proposed for use in underground structures, such as prefabricated utility ...
Converting Iron Mine Tailings into Composite Aggregates for Ultrahigh-Performance Mortar
Publisher: American Society of Civil Engineers
Abstract: Iron tailings (IT) are by-products of iron ore mining, which have the characteristics of high stockpile and low cost. Recycling IT as alternatives for high-quality quartz sand (QS) in ultrahigh-performance mortar (UHPM) ...
Frequency Effect on the Compressive Fatigue Behavior of Ultrahigh Toughness Cementitious Composites: Experimental Study and Probabilistic Analysis
Publisher: American Society of Civil Engineers
Abstract: Ultrahigh toughness cementitious composite is a cementitious material that exhibits the characteristic of pseudo strain hardening under uniaxial tension, and has potential use in structures that experience repeated or ...
