This paper uses the concept of ramp superposition to analyse the influence of a road profile on the beam stresses and to determine the critical sections where maximum stresses develop. The method also allows identifying those road segments that contribute in a higher degree to those stresses.||Type of material:||Conference Publication||Publisher:||Civil-Comp Press||Copyright (published version):||2007 Civil-Comp Press and Saxe-Coburg Publications||Keywords:||Bridge; Dynamics; Vehicle; Interaction; Bending moment; Ramp; Superposition; ISO profile||DOI:||10.4203/ccp.86.196||Language:||en||Status of Item:||Peer reviewed||Conference Details:||Proceedings of the Eleventh International Conference on Civil, Structural and Environmental Engineering Computing, St. Julians, Malta, 18-21 September, 2007|
