RISSingle-Side Shear Bond Strength and OTZ Microstructure of UHPC Repair Materials with Concrete Substrate
Publisher: ASCE
Abstract: In this study, the effects of ultrahigh-performance concrete (UHPC) and normal-strength concrete (NSC) as repair materials on the bond strength and overlay transition zone (OTZ) microstructure were investigated. The ...
Stability and Dynamics Analysis of In-Plane Parametric Vibration of Stay Cables in a Cable-Stayed Bridge with Superlong Spans Subjected to Axial Excitation
Publisher: ASCE
Abstract: Stay cables are prone to parametric vibrations, which might severely affect the serviceability and safety of cable-stayed bridges. This paper investigates the stability and dynamic characteristics of in-plane parametric ...
Experimental Investigation on Vortex-Induced Vibration Mitigation of Stay Cables in Long-Span Bridges Equipped with Damped Crossties
Publisher: American Society of Civil Engineers
Abstract: In this study, based on the high energy-dissipating capacity of viscoelastic dampers with shearing deformation, damped stay cable crossties were proposed to mitigate the vortex-induced vibration (VIV) of stay cables in ...
