Publisher: American Society of Civil Engineers
Turbulent Jet Mixing Enhancement and Control Using Self-Excited Nozzles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new self-excited jet methodology was developed for the mixing enhancement of jet fluid with its surrounding, quiescent, stagnant, or coflowing fluid. The nozzles, of a square or rectangular ...
Nonlinear SDOF Model for Dynamic Response of Structures under Progressive Collapse
Publisher: American Society of Civil Engineers
Abstract: The transient dynamic response of the substructures above a removed column is the most direct and realistic to demonstrate the structural performance against progressive collapse. To efficiently obtain the transient dynamic ...
Nonlinear SDOF Model for Progressive Collapse Responses of Structures with Consideration of Viscous Damping
Publisher: American Society of Civil Engineers
Abstract: The effect of damping on progressive collapse responses of structures is typically ignored. However, the margin of conservatism resulting from ignoring damping is not well known. Therefore, in this paper, a nonlinear ...

Publisher: American Society of Civil Engineers
Abstract: A direct eigenvalue analysis approach to solving the stability problem of randomly and periodically parametrically excited linear systems is developed based on the response moment stability, Floquet theorem, Fourier series, ...
Applications of Erosion Hotspots for Watershed Investigation in the Appalachian Hills of the United States
Publisher: American Society of Civil Engineers
Abstract: Soil erosion, more than any other factor, has more significant and direct impacts on a hydrological watershed in terms of environmental problems. After deriving the erosion hotspots, this study used them to investigate two ...
A New Approach for Interval Dynamic Analysis of Train-Bridge System Based on Bayesian Optimization
Publisher: ASCE
Abstract: A train-bridge system (TBS) is inevitably subjected to parameter uncertainty, which leads to variability in its dynamic responses. In practice, it is difficult to characterize parameter uncertainty using precise probability ...
Bayesian Modeling Approach for Forecast of Structural Stress Response Using Structural Health Monitoring Data
Publisher: American Society of Civil Engineers
Abstract: The advancement in structural health monitoring (SHM) technology has been evolving from monitoring-based diagnosis to monitoring-based prognosis. The structural stress response derived by the measured strain data is ...
Binary Segmentation for Structural Condition Classification Using Structural Health Monitoring Data
Publisher: American Society of Civil Engineers
Abstract: Structural health monitoring (SHM) is the process of conducting structural condition diagnosis and prognosis based on appropriate analyses of in situ measurement data. Direct assessment of structural condition using time ...
Design and Application of Double-Parallelograms-Based Tuned Mass Damper for Low-Frequency Vibration Absorption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low-frequency vibration suppression is challenging in practical engineering problems due to the harsh requirement for vibration reduction devices, which requires constant low stiffness over a wide amplitude range. A passive ...
