Análise da interação trilho-viaduto

Abstract

A rigorous approach making use of a computer program for three-dimensional analysis of structures which considers the interactions of forces between rails and railway bridge structure is presented. The forces are due to thermal variations and to forces caused by trains passing over the structure. The acting forces are distributed to the rails and structures by means of the ballast which is represented by a constitutive relation between relative displacements and applied forces.
