Semi-analytical determination of natural frequencies and mode shapes of multi-span bridge decks

Rezaiguia, Abdelouahab ; Laefer, Debra F. (Elsevier, 2009-12)

The determination of the natural frequencies and mode shapes of structures requires an analytical, semi-analytical or numerical method. This paper presents a new semi-analytical approach to determine natural frequencies ...
The use of micro-simulation for congested traffic load modelling of medium- and long-span bridges

O'Brien, Eugene J. ; Hayrapetova, Alisa ; Walsh, Cathal (Taylor & Francis, 2011-11-28)

This paper presents a new approach to the modelling of congested traffic loading events on long span bridges. Conventional traffic load models are based on weigh-in-motion data of non-congested traffic, or something similar ...
