Abstract

This paper describes the dynamic considerations in the design of a long span (200 to 600 ft) cable-stayed guideways for future tracked levitated vehicles (TLV’s) which will be used for high speed ground transportation. A design approach is described in which a cable-stayed guideway structure can be synthesized to simulate the behavior of a beam on elastic foundation. This result is achieved by the “cable-tuning” approach, in which the cable stays are selected to achieve an equivalent uniform elastic foundation. The design approach insures that the live load deflection of the trackway beam is manifested as a traveling wave which moves horizontally at the same velocity as the vehicle, thereby minimizing dynamic interaction problems. Parametric results are presented for the dynamic response of a beam on elastic foundation. Optimum cable and tower configurations are developed for this guideway concept and a typical conceptual design is described.
