Development of a Bridge Weight-in-Motion (BWIM) system for structural safety and reliability


This project is developed as part of a cooperation agreement between DNIT and UFSC managed by the Laboratory of Transportation (LABTRANS). The researchers of CORE are responsable for the development of a BWIM system for structural safety and reliability, with focus on vehicles that require a special traffic authorization.  BWIM uses strain data from sensors located under the bridge in order to characterize actual traffic loading, bridge structural behavior, among others. The tecnical challenge is to filter such data identifying statical loading, dynamical effects and measurement error. For this purpose, CORE’s team is developing new methods based on Regularization Theory and Bayesian Estimation.
