Interaction among moving inertial loads and footbridge

Henryk Ciurej


The aim of the paper is formulation of equations expressing interaction among moving inertial
loads of pedestrians and cyclists and a footbridge. The equations of motion of all interacting
structures was shown. The fundamental matrices relations representing the interaction of all
substructures and a deck was presented. The shown formulas allow to analysis of responses of
structures with simultaneous excitations of forces changing in time and space, inertial moving
loads, tuned mass dampers and kinematic excitations.
