RISDischarge Coefficient and Head Loss under Sluice Gates with Small Opening
Publisher: ASCE
Abstract: The water flow under a high-dam gate with a small opening has rarely been studied. The discharge coefficient and head loss under sluice gates are studied experimentally, with the relative gate opening less than 0.10, ...
Floating Offshore Wind Turbine Dynamics: Large-Angle Motions in Euler-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Floating structures have been proposed to support offshore wind turbines in deep water, where environmental forcing could subject the rotor to meaningful angular displacements in both precession ...
Pedestrian Cognition of Street Structure and Route Choices When Strolling: Comparative Study Based on Two Experimental Methods
Publisher: ASCE
Abstract: This study aimed to consider the street structure and the relationship between such structure and people’s route choices as well as people’s street structure concerns or preferences based on a common mapping tool. We used ...
Improvement of Poststall Performance of NACA 0015 Airfoil Using Leading-Edge Synthetic Jet Array
Publisher: ASCE
Abstract: Wind tunnel experiments were conducted to explore the control effect of a synthetic jet actuator array placed at the leading edge of a National Advisory Committee for Aeronautics (NACA) 0015 airfoil at two Reynolds numbers ...
PIV Measurement of Separated Flow in a Square Channel With Streamwise Periodic Ribs on One Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, particle image velocimetry (PIV) is used to investigate the physical process of separated flow in a square channel roughened with periodically transverse ribs on one wall. The ...
Semi-Analytical Solution to One-Dimensional Consolidation for Unsaturated Soils with Exponentially Time-Growing Drainage Boundary Conditions
Publisher: American Society of Civil Engineers
Abstract: This paper presents a semi-analytical solution to Fredlund and Hasan’s one-dimensional consolidation for unsaturated soils subjected to exponentially time-growing drainage-boundary conditions. Two variables are introduced ...
Prestress Loss Diagnostics in Pretensioned Concrete Structures with Corrosive Cracking
Publisher: ASCE
Abstract: Concrete cracking induced by strand corrosion can degrade bond strength and lead to prestress loss. A novel model is proposed to predict corrosion-induced prestress loss in pretensioned concrete structures. The coupling ...
Probabilistic Life Prediction for Reinforced Concrete Structures Subjected to Seasonal Corrosion-Fatigue Damage
Publisher: ASCE
Abstract: The coupled effect of corrosion and fatigue deteriorates the performance of reinforced concrete (RC) structures. This paper proposes a novel framework for the probabilistic life prediction of aging RC structures under ...
Corrosion Fatigue Crack Propagation Mechanism of High-Strength Steel Bar in Various Environments
Publisher: ASCE
Abstract: This paper investigated the corrosion fatigue crack propagation mechanism of high-strength steel bar HRB400 in various corrosive environments. Fatigue crack growth (FCG) tests were conducted under different fatigue loading ...
