Evaluation of Viscous Dampers for Stay-Cable Vibration Mitigation
Publisher: American Society of Civil Engineers
Abstract: Many cable-stayed bridges around the world have displayed excessive and unanticipated vibrations of the main stays, often associated with the simultaneous occurrence of wind and rain, and mitigation of these vibrations has ...
Free Vibrations of Taut Cable with Attached Damper. I: Linear Viscous Damper
Publisher: American Society of Civil Engineers
Abstract: Free vibrations of a taut cable with an attached linear viscous damper are investigated in detail using an analytical formulation of the complex eigenvalue problem. This problem is of considerable practical interest in the ...
Free Vibrations of Taut Cable with Attached Damper. II: Nonlinear Damper
Publisher: American Society of Civil Engineers
Abstract: Free vibrations of a taut cable with a nonlinear power-law damper attached near the end are considered. An approximate analytical solution for the amplitude-dependent effective damping ratios in each mode is developed by ...
Load‐Deflection Behavior of Space‐Based Inflatable Fabric Beams
Publisher: American Society of Civil Engineers
Abstract: The use of inflatable structures has often been proposed for aerospace applications. The advantages of such structures include low launch weight and easy assembly. To consider using inflated fabric beams in aerospace ...
Low-Rise Steel Structures under Directional Winds: Mean Recurrence Interval of Failure
Publisher: American Society of Civil Engineers
Abstract: The Commentary to the American Society of Civil Engineers (ASCE) Standard 7-05 states that the nominal mean recurrence interval (MRI) of the wind speed inducing the design strength is about 500 years if the specified load ...
