... deck since this is all that is required to capture many of the central control-theoretic issues. This model will typically represent the lowest-frequency heave and torsional modes of the bridge structure, which have symmetrical mode shapes . For some three-dimensional suspended bridge structures...

... or residual stresses. The results show significant differences from the ideal bond case. Comparisons made to a three-dimensional finite element analysis show a good agreement. 09 02 2007 28 08 2007 08 04 2008 beams (structures) bending bridges (structures) cantilevers finite element...

... to decouple the equation of motion, such as the state space approach ( 4 ) and the finite element method (FEM) ( 5 ). The modal superposition technique has good accuracy for identification but it demands heavy computation when multiple vehicles cross a multispan bridge structure. The FEM approach is flexible...
