Název v původním jazyce

Vehicle/bridge interaction dynamics for high speed rail suspension bridges considering multiple support excitations

Popis výsledku v původním jazyce

In this study, a railway suspension bridge is modeled as a suspended beam and the train over it as a sequence of moving sprung masses. To investigate the bridge response subjected to simultaneous actions of moving load and earthquake-induced support motions, the total response of the suspended beam under ground motions can be decomposed into two parts: the pseudo-static response and the inertia-dynamic component, in which the pseudostatic displacement is analytically obtained by exerting the support movements on the suspended beam statically and the governing equations in terms of the inertia-dynamic component as well as moving oscillators are transformed into a set of nonlinearly coupled generalized equations by Galerkin?s method. When conducting thedynamic response analysis of a suspended beam subject to moving vehicles and multiple support excitations, one needs to deal with nonlinear coupling vibration problems with time-dependent boundary conditions. Instead of solving the couple
