RISFracture and Time-Varying Multifractal Behaviors of Single-Flawed Red Sandstone with Different Wavilness Angles
Publisher: ASCE
Abstract: To study the cracking behaviors and deformation damage process of single-flawed red sandstone with different wavilness angles, a series of uniaxial compression tests are conducted to investigate the effect of wavilness ...
3D Digital Analysis of Cracking Behaviors of Rocks through 3D Reconstruction Model under Triaxial Compression
Publisher: ASCE
Abstract: The cracking behaviors of rocks significantly affect their mechanical properties. In this paper, a digital analysis approach with X-ray Computed Tomography (CT) imagery is developed to investigate the cracking and mechanical ...
Probabilistic Assessment for Slope Using the Generalized Chebyshev Inequalities
Publisher: ASCE
Abstract: This paper aims to estimate the probability of failure (Pf) of slope based on Chebyshev inequalities. Traditionally, for a slope reliability analysis, the supposed distribution types of shear strength parameters are employed; ...
3D Numerical Study on the Growth and Coalescence of Pre-existing Flaws in Rocklike Materials Subjected to Uniaxial Compression
Publisher: American Society of Civil Engineers
Abstract: A novel, meshless numerical method, called general particle dynamics (GPD), is proposed to simulate the initiation, propagation, and coalescence of three-dimensional (3D), pre-existing penetrating and embedded flaws as ...
Design Criteria for Box Columns Under Biaxial Loading
Publisher: American Society of Civil Engineers
Abstract: Several design criteria for isolated, simply supported welded rectangular box‐column subjected to compression and combined with biaxial bending are examined. The load carrying capacity of the columns is presented in terms ...
Seasonal Modulations of El Niño–Related Atmospheric Variability: Indo–Western Pacific Ocean Feedback
Publisher: American Meteorological Society
Abstract: AbstractThe spatial structure of atmospheric anomalies associated with El Niño?Southern Oscillation varies with season because of the seasonal variations in sea surface temperature (SST) anomaly pattern and in the ...
Influence of Hydrodynamics on the Performance of a Biofilm Airlift Suspension Reactor
Publisher: American Society of Civil Engineers
Abstract: Five biofilm airlift suspension (BAS) reactors filled with ceramic materials as biocarriers were used to investigate the hydrodynamics, liquid mixing, and biofilm detachment kinetics in the BAS reactor. A mathematical model ...
Three-Dimensional Stability Analysis of Bank Slopes with Reservoir Drawdown Based on Rigorous Limit Equilibrium Method
Publisher: ASCE
Abstract: The fluctuation of reservoir water levels has significant impact on bank slope stability near a reservoir. Therefore, it is necessary to analyze the stability of bank slopes with reservoir drawdown. In this paper, a novel ...
The Influence of Traffic Distribution by Route Choice Behavior Under the Condition of No Inducing Information Based on the Limited Rational Fuzzy Game
Publisher: American Society of Civil Engineers
Abstract: When no guidance information is available, drivers often depend on recent experience to select a travel route. This paper is based on the theory of behavior reinforcement, establishing a vehicle route choosing model without ...
Numerical Simulation of Failure Process of Rock-Like Materials Subjected to Impact Loads
Publisher: American Society of Civil Engineers
Abstract: In this research, a novel meshless numerical method, termed general particle dynamics (GPD), to simulate crack initiation, propagation, and coalescence in rock-like materials subjected to impact loads was developed. In the ...
