Unsteady Theoretical Analysis on the Wake-Induced Vibration of Suspension Bridge Hangers
Publisher: American Society of Civil Engineers
Abstract: The hangers on long-span suspension bridges are significantly prone to wind-induced vibrations due to their light mass, low frequency, and small structural damping. These vibrations are known to cause fatigue problems and ...
Parameter and Aerodynamic Force Identification of Single-Degree-of-Freedom System in Wind Tunnel Test
Publisher: American Society of Civil Engineers
Abstract: The extended Kalman filter with unknown inputs (EKF-UI) method has been extensively studied for application in system and input identification of multiple-degrees-of-freedom systems. The inverse problem is, however, ...
Experimental Investigation on Quasi-Steady and Unsteady Self-Excited Aerodynamic Forces on Cable and Rivulet
Publisher: American Society of Civil Engineers
Abstract: The aerodynamic forces on the cable and rivulet are usually determined by the quasi-steady method, which cannot take signature turbulence into account. Furthermore, the oscillation of the cable and rivulet might have ...
Comparative Study on the Wake-Induced Vibration of PWS and WR Six-Cable Hangers of Suspension Bridges and Its Mitigation
Publisher: ASCE
Abstract: With the continuous increase in the span of suspension bridges, six-cable hangers have been gradually adopted to meet the load requirements in the design of suspension bridges. However, the aerodynamic interference between ...
