Complex Variable Solution of Interference Effect of Two Nearby Strip Footings on Layered Soil
Publisher: ASCE
Abstract: This study provides a solution for determining stress and displacement measurements of layered soil under the interaction of two adjacent strip footings by using conformal transformation methods (CTMs) in complex variable ...
Adsorptive Removal of Parts per Million Level Selenate Using Iron-Coated GAC Adsorbents
Publisher: American Society of Civil Engineers
Abstract: Selenate removal by adsorption using iron-coated granular activated carbons (Fe-GACs) is reported in this study. Adsorption kinetics and equilibrium experiments with initial selenium concentration of 1 mg/L were conducted ...
Smoothed Classic Yield Function for C2 Continuities in Tensile Cutoff, Compressive Cap, and Deviatoric Sections
Publisher: ASCE
Abstract: In elastoplastic analyses, a yield function needs convexities and C1 continuities, to meet the requirement of return mapping algorithms. However, many classic criteria in geotechnical engineering have shortages: either ...
Refined Peridynamic Modeling of Bond-Slip Behaviors between Ribbed Steel Rebar and Concrete in Pull-Out Tests
Publisher: ASCE
Abstract: Peridynamics (PD) has been increasingly used to study the damage behaviors of reinforced concrete (RC) structures due to its strong capacity in analyzing discontinuous problems. In this paper, bond-based peridynamics (BPD) ...
Effect of Partially Imperfect Interface on Dynamic Response of a Circular Lined Tunnel in an Elastic Half-Space Subjected to Plane SH Waves
Publisher: ASCE
Abstract: Loose zones and voids often exist behind the crown and the spandrel of a tunnel, and the interface between a tunnel lining and its surrounding medium is therefore partially debonded. To elucidate the partially imperfect ...
Temperature Prediction for Expressway Pavement Icing in Winter Based on XGBoost–LSTNet Variable Weight Combination Model
Publisher: ASCE
Abstract: Ice cover on pavement may reduce the road adhesion coefficient and increase the crash risks, which might result in more traffic crashes. The primary factor utilized to assess whether the wet pavement is icy or not is the ...
Real-Time Optimization of Urban Rail Transit Train Scheduling via Advantage Actor–Critic Deep Reinforcement Learning
Publisher: American Society of Civil Engineers
Abstract: Under the condition of urban rail transit uncertainty of passenger demand and the high frequency of departure intervals, this study presents an innovative real-time urban rail transit (URT) train service scheduling control ...
