RISDynamics of Plate Generated by Moving Harmonic Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thin plate resting on a Winkler elastic foundation subject to a moving harmonic load can be used as the model for highway and airport pavement under moving vehicle load and many other ...
Steady-State Dynamic Response of a Kirchhoff’s Slab on Viscoelastic Kelvin’s Foundation to Moving Harmonic Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, fast Fourier transform and complex analysis are used to analyze the dynamic response of slabs on a viscoelastic foundation caused by a moving harmonic load. Critical speed and ...
Developing Spectrum-Based Models for International Roughness Index and Present Serviceability Index
Publisher: American Society of Civil Engineers
Abstract: This paper presents a theoretical model for determining international roughness index (IRI) and present serviceability index (PSI) in term of power spectral density (PSD) roughness. Frequency response functions of quarter-car ...
Steady-State Dynamic Response of a Bernoulli–Euler Beam on a Viscoelastic Foundation Subject to a Platoon of Moving Dynamic Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Bernoulli–Euler beam resting on a viscoelastic foundation subject to a platoon of moving dynamic loads can be used as a physical model to describe railways and highways under traffic loading. ...
Three-Dimensional Reconstruction of Macrotexture and Microtexture Morphology of Pavement Surface Using Six Light Sources–Based Photometric Stereo with Low-Rank Approximation
Publisher: American Society of Civil Engineers
Abstract: Inadequate skid resistance of pavement surface is a substantial reason for traffic accidents. There is a close relationship between sliding resistance and characteristics of texture morphology, demanding high precision and ...
Transient Wave Propagation in Multilayered Viscoelastic Media: Theory, Numerical Computation, and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper extends the classical problem of transient wave propagation in multilayered solids to transient wave propagation in multilayered viscoelastic solids. Laplace and Hankel transforms and ...
Generalized Maxwell Viscoelastic Contact Model-Based Discrete Element Method for Characterizing Low-Temperature Properties of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: A universal asphalt concrete discrete element method (DEM) model was established in this paper. Coarse aggregates consisting of balls bonded by elastic contact models were simulated using irregular particles. Asphalt mastic ...
Pavement Condition Assessment Using Fuzzy Logic Theory and Analytic Hierarchy Process
Publisher: American Society of Civil Engineers
Abstract: This paper integrates the advantages of the analytic hierarchy process (AHP) and fuzzy logic theory and develops a new approach for pavement condition assessment and project prioritization. Roughness, deflection, surface ...
Reliability Analysis of Vehicle Stability on Combined Horizontal and Vertical Alignments: Driving Safety Perspective
Publisher: American Society of Civil Engineers
Abstract: A driver/vehicle/road closed loop dynamic simulation model considering three-dimensional (3D) alignment was established using Matlab/Simulink for reliability analysis of vehicle stability on the combined horizontal and ...
Nonstationary Dynamic Pavement Loads Generated by Vehicles Traveling at Varying Speed
Publisher: American Society of Civil Engineers
Abstract: Many of the existing studies on vehicle dynamics assume that vehicles travel at a constant speed on a homogeneous pavement surface. In this paper the effect of nonstationary surface excitation to vehicle dynamics are ...
