Control of Vibrations due to Moving Loads on Suspension Bridges

Nonlinear Analysis, 2006
The flexibility and low damping of the long span suspended cables in suspension bridges makes them prone to vibrations due to wind and moving loads which affect the dynamic responses of the suspended cables and the bridge deck.

The response of a floating ice sheet to an accelerating line load [PDF]

, 2003
The two-dimensional response of a thin, floating sheet of ice to a line load that accelerates from rest at $t = 0$ to a uniform velocity V for $t \geq T$ is determined through an integral-transform solution of the linearized equations of motion.

The Extra Load Index as a method for comparing the relative economy of load carriage systems. [PDF]

, 2010
The Extra Load Index (ELI) has been proposed as a suitable method of assessing the relative economy of load carriage systems. The purpose of this study was to determine, based on empirical evidence, that the ELI can accommodate variations in both body ...
