Analysis of Thermal Stress in Asphalt Overlay Based on Thermal-viscoelasticity Theory
Publisher: American Society of Civil Engineers
Abstract: The thermal stress responses of various structural asphalt pavement under different cooling conditions were analyzed considering thermal-viscoelasticiy of asphalt pavement mixture by using finite element software. The ...
Unify Energy Harvesting and Vibration Control Functions in Randomly Excited Structures with Electromagnetic Devices
Publisher: American Society of Civil Engineers
Abstract: With the extensive studies on energy harvesting via electromagnetic devices in civil or mechanical structures, a novel dual-function device, termed electromagnetic damping and energy harvesting (EMDEH) device, has been ...
Vibration-Based Structural Damage Identification under Varying Temperature Effects
Publisher: American Society of Civil Engineers
Abstract: Vibration-based methods are promising for damage identification; however, their capabilities for damage identification under temperature variations are usually limited. In the paper, a vibration-based nondestructive global ...
Damage Identification for Beam Structures Using the Laplace Transform-Based Spectral Element Method and Strain Statistical Moment
Publisher: American Society of Civil Engineers
Abstract: The Laplace transform-based spectral element method (LTSEM) can avoid some limitations of the conventional Fourier transform-based spectral element method (FTSEM) in handling finite-length structures, such as the wrap ...
Identification of Free–Free Flexibility for Model Updating and Damage Detection of Structures
Publisher: American Society of Civil Engineers
Abstract: Aerospace and civil structures are sometimes measured under free constraints. In many substructuring methods, the substructures are independently analyzed with free constraints as well. When a structure is free because of ...
Fire-Resistance Behavior of Completely Overlapped Tubular Joints under Lap Brace Axial Loading
Publisher: American Society of Civil Engineers
Abstract: The fire resistance behavior of completely overlapped tubular joints was experimentally and numerically investigated. Three completely overlapped tubular joint specimens with different geometric properties were tested to ...
Feasible Range for Midtower Lateral Stiffness in Three-Tower Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: This study investigates the structural characteristics of midtowers in three-tower suspension bridges and proposes a direct approach to determining feasible midtower stiffness for preliminary designs. The lateral stiffness ...
Power Analysis of SDOF Structures With Tuned Inerter Dampers Subjected to Earthquake Ground Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tuned inerter dampers (TID) have been demonstrated as efficient energy dissipation devices for seismic response control. However, its potential capability for energy harvesting remains largely unexplored. Here, we present ...
