Improving the Wind Stability of Suspension Bridges during Construction
Publisher: American Society of Civil Engineers
Abstract: The wind stability of suspension bridges in the construction phase can often be more problematic than in the final state. In this paper, numerical wind stability analyses are performed for the erection process of both ...
Improving Suspension Bridge Wind Stability with Aerodynamic Appendages
Publisher: American Society of Civil Engineers
Abstract: The influence of aerodynamic appendages on the wind stability of box-girder suspension bridges is examined, with special reference to the stability of bridges with very long spans (above 2,000 m). Aerodynamic appendages ...
Preliminary Design of Prestressed Concrete Stress Ribbon Bridge
Publisher: American Society of Civil Engineers
Abstract: A stress ribbon bridge is a very slender structure in which the deck hangs in a suspended cablelike form. The structural response of this kind of structure is complex because of the combined effects of geometric nonlinearity, ...
Interface Behavior in Fiber-Reinforced Polymer-Strengthened Beams Subjected to Transverse Loads: Maximum Transferred Force
Publisher: American Society of Civil Engineers
Abstract: Experimental results of externally bonded strengthened beams, available to date in the literature, have shown the existence of some types of brittle failures that involve the premature laminate debonding before reaching ...
Design Proposal to Avoid Peeling Failure in FRP-Strengthened Reinforced Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: According to the available experimental work, the most common failure in existing structures strengthened by plate bonding is the laminate peeling off. In the last few years, an important effort in the development of ...
