Retrofitting Suspension Bridges Using Distributed Dampers
Publisher: American Society of Civil Engineers
Abstract: Suspension bridges in the Central and Eastern United States (CEUS) were built before recent advances in earthquake engineering, and may be susceptible to seismic ground motions. A retrofit strategy is proposed in which ...
Discussion of “Pipe Efficiency Analysis at a Water Utility” by Amarjit Singh and Stacy Adachi
Publisher: American Society of Civil Engineers
Multi-Axial Mechanical Stimulation of HUVECs Demonstrates That Combined Loading is not Equivalent to the Superposition of Individual Wall Shear Stress and Tensile Hoop Stress Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over the past 25 years, many laboratory based bioreactors have been used to study the cellular response to hemodynamic forces. The vast majority of these studies have focused on the effect ...
Hydraulic Performance of Aggregate Beds with Perforated Pipe Underdrains Flowing Full
Publisher: American Society of Civil Engineers
Abstract: Results are presented from an experimental study of the stage discharge relationship for a porous pipe buried under loose laid aggregate. A series of steady-state experiments were performed in which the depth of flow over ...
An Extended Finite Element Method for Two-Phase Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An extended finite element method with arbitrary interior discontinuous gradients is applied to two-phase immiscible flow problems. The discontinuity in the derivative of the velocity field is ...
Shear Buckling of Sandwich, Fiber Composite and Lattice Columns, Bearings, and Helical Springs: Paradox Resolved
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As shown three decades ago, in situations where the initial stresses before buckling are not negligible compared to the elastic moduli, the geometrical dependence of the tangential moduli on ...
Size Effect on Flexural Strength of Fiber-Composite Laminates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The size effect on the flexural strength (or modulus of rupture) of fiber-polymer laminate beams failing at fracture initiation is analyzed. A generalized energetic-statistical size effect law ...
Greater Future U.K. Winter Precipitation Increase in New Convection-Permitting Scenarios
Publisher: American Meteorological Society
Abstract: For the first time, a model at a resolution on par with operational weather forecast models has been used for national climate scenarios. An ensemble of 12 climate change projections at convection-permitting (2.2 km) scale ...
