RISInfluence of Carbon Nanotubes on Wear of Carbide/Cobalt Micropunch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Carbon nanotubes (CNTs) coated on a tungsten carbide/cobalt (WC/Co) micropunch (150 خ¼m in diameter) and their effect on the wear of micropunches were investigated. CNTs were synthesized by homemade method. After the ...

Shake Table Test on a Long-Span Cable-Stayed Bridge with Viscous Dampers Considering Wave Passage Effects
Publisher: ASCE
Abstract: This work focused on the damping effectiveness of additional longitudinal viscous dampers employed for seismic control of long-span cable-stayed bridges considering wave passage effects. A 1/35-scale physical model scaled ...
Experimental Study on Air- and Water-Inflated Double-Rubber Dams
Publisher: ASCE
Abstract: A double rubber dam with the upper dam inflated by air and lower dam inflated by water is proposed in this paper. Large-scale physical hydraulic model tests are carried out to investigate the influence of the inflated air ...
Reliability Analysis and Design of Vertically Loaded Piles in Spatially Variable Soils
Publisher: ASCE
Abstract: At present, the reliability analysis and design method of vertically loaded piles embedded in spatially variable soils is difficult to be applied in practical engineering due to the huge computation effort required. To ...
A Novel Low-Pressure Release Method Based on Inlet Regulation for Users with Low Demand Scenario
Publisher: ASCE
Abstract: Due to the mismatch between gas production and consumption in the gas delivery system (GDS), reduced customer demand can easily lead to overpressure and gas release. Companies mainly use high-pressure release (HPR) to lower ...
Fiscal Implications of Disasters and the Managed Retreat Thereafter: Evidence from Hurricane Sandy
Publisher: American Society of Civil Engineers
Abstract: Local governments stand at the frontline of responding to natural hazards, but they often lack the capacity and resources necessary to manage such crises. Disasters can affect local government spending and revenue streams ...
Dynamic Ship-Impact Load on Bridge Structures Emphasizing Shock Spectrum Approximation
Publisher: American Society of Civil Engineers
Abstract: In current design specifications, a static procedure using code-prescribed loads has been commonly used to design bridges against ship collisions. However, the collision-induced response may be greatly underestimated as a ...
Thermal-Mechanical Model for Predicting the Wind and Seismic Response of Viscoelastic Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper presents a simplified coupled thermal-mechanical model for the modelling of viscoelastic dampers with temperature- and frequency-dependent properties subjected to long-term and short-term dynamic loading due to ...
Sliding Mode Control for a Nonlinear Aeroelastic System through Backstepping
Publisher: American Society of Civil Engineers
Abstract: This paper considers an aeroelastic two-dimensional wing-flap system with uncertainty and external disturbance. Nonlinear stiffness in pitch is expressed as the second-order polynomial form. In the uncontrolled aeroelastic ...
