SENSITIVITY ANALYSIS OF TRACK VIBRATIONS DUE TO VERTICAL STIFFNESS VARIATION IN...
Dimitrovová, Zuzana; Varandas, José N.; de Almeida, João R.; Silva, Manuel G.A.High speed trains, when crossing regions with abrupt changes in vertical stiffness of the track and/or subsoil, may generate excessive ground and track vibrations. There is an urgent need for specific analyses of this problem so as to allow reliable esimates of vibration amplitude. Full understanding of these phenomena will lead to new construction solutions and mitigation of undesirable features. In this paper...
Influence of cross section geometry on the confinement of reinforced concrete c...
Paula, Raquel F.; Silva, Manuel G.; Vinagre, JoãoComunicação apresentada em International Symposium Polymers in Concrete (ISPIC 2006), Guimarães, 2006 ; Confinement effectiveness of externally bonded FRP jackets depends on different parameters namely type of concrete, steel reinforcement, FRP jacket stiffness (type of FRP, number of plies and design of wrap), shape of cross section, radius of corners for non-circular sections, and loading conditions. In orde...
