RISCracking Analysis of Plain Concrete under Coupled Heat Transfer and Moisture Transport Processes
Publisher: American Society of Civil Engineers
Abstract: A smeared cracking approach is developed in this paper to simulate the crack propagation in plain concrete caused by coupled heat transfer and moisture transport processes. The cracking state of each concrete element is ...
Case Study: Two-Dimensional Model Simulation of Channel Migration Processes in West Jordan River, Utah
Publisher: American Society of Civil Engineers
Abstract: The paper presents the application of a two-dimensional depth-averaged numerical model to simulate the lateral migration processes of a meandering reach in the West Jordan River in the state of Utah. A new bank erosion ...
Four Dimensional Holospectrum—A New Method for Analyzing Force Distributions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new method, called four dimensional (4D) holospectrum, is introduced for analyzing force distributions. First, it is shown that the dynamics of a three dimensional force can ...
Sensitivity Analysis of Nonequilibrium Adaptation Parameters for Modeling Mining-Pit Migration
Publisher: American Society of Civil Engineers
Abstract: The nonequilibrium adaptation parameters of a depth-averaged two-dimensional hydrodynamic and sediment transport model were examined in the study. Calculated results were compared to data measured in two sets of published ...
Closure to “Sensitivity Analysis of Nonequilibrium Adaptation Parameters for Modeling Mining-Pit Migration” by Dong Chen, Kumud Acharya, and Mark Stone

An Interdecadal Enhancement of the Impact of ENSO on the Summer Northeast Asian Circulation around 1999/2000 through the Silk Road Pattern
Publisher: American Meteorological Society
Abstract: In this study, we find that the negative relationship between El Niño–Southern Oscillation (ENSO) and summer Northeast Asia (NEA; 30°–50°N, 110°–140°E) circulation, especially the geopotential height anomalies in the upper ...
Role of Workforce Management in Bridge Superstructure Labor Productivity
Publisher: American Society of Civil Engineers
Abstract: There have been many studies on different aspects of the construction process in regard to how they each impact construction productivity. In reviewing the documentation of this research, very few articles were located ...
Determination of the Main Direction of a Sliding Body Based on a Three-Dimensional Finite-Element Limit-Equilibrium Method
Publisher: ASCE
Abstract: The safety evaluation of three-dimensional rock or soil slopes strongly depends on the factor of safety based on the potential direction of sliding body. In fact, considering the objectivity of sliding, there should be a ...
Utilization of Waste Adsorbent Generated after Ca/Al-LDH Adsorption of High-Concentration Phosphate: Fluorine Removal
Publisher: American Society of Civil Engineers
Abstract: Ca–Al-layered double hydroxide (Ca/Al-LDH) is an excellent sorbent for wastewater decontamination and is widely used in the treatment of this phosphate and fluoride-containing wastewater. In this study, we propose a strategy ...
Second-Law Thermodynamic Comparison and Maximal Velocity Ratio Design of Shell-and-Tube Heat Exchangers With Continuous Helical Baffles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shell-and-tube heat exchangers (STHXs) have been widely used in many industrial processes. In the present paper, flow and heat transfer characteristics of the shell-and-tube heat exchanger with ...
