DYNAMIC CONSIDERATIONS IN THE DESIGN OF A CABLE-STAYED GUIDEWAY

This paper describes the dynamic considerations in the design of long span (200 to 600 feet) cable-stayed guideways for tracked air cushion vehicles (TACV's). 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. A tower configuration is then selected to minimize the effect of tower structural compliance, relative to the vertical deviation of the vehicle as it traverses the span. Therefore, the live load deflection of the trackway structure is manifested as a traveling wave which moves horizontally at the same speed as the vehicle. This approach satisfies the dynamic requirements for acceptable passenger ride comfort and minimal vehicle/guideway dynamic interaction.
