✦ Synopsis

This paper deals with the free vibration analysis of a multi-span beam with an arbitrary number of flexible constraints. Each span of the continuous beam is assumed to obey Timoshenko beam theory. Considering the compatibility requirements on each constraint point, the relationships between two adjacent spans can be obtained. By using a transfer matrix method, eigensolutions of the entire system can be determined. Some numerical results are shown to present the effects of support stiffness and locations.

The combined effects of disorder and structural damping on the dynamics of a multi-span beam with slight randomness in the spacing between supports are investigated. A wave transfer matrix approach is chosen to calculate the free and forced harmonic responses of this nearly periodic structure. It is

By taking a pipe as Timoshenko beam, in this paper the original 4-equation model of pipe conveying fluid was modified by taking the dynamic effects of fluid into account. The shape function that always used in the finite element method was replaced by the exact wave solution of the modified four equ
