LOAD SPECTRA FOR BRIDGE EVALUATION

SPECTRE DE CHARGES POUR L'EVALUATION DES PONTS

Evaluating existing bridges can be more complex then designing new structures. It is suggested herein that bridge inspections should include load history as well as bridge condition. A recently developed weigh-in-motion technology reduces uncertainty by accurately determining records of truck weights, bridge response and repetitive stress-spectra. Reliability predictions can further assist decision-making by modelling fatigue failure and overall fail-safe capacity. Applications include inspection, posting, legal limits, enforcement, rating and permit assessments. Such evaluation-related problems can all benefit from improved load modelling and site-specific loading statistics formulated into a reliability model.
