The proposed project will develop hybrid Bridge Weigh-In- Motion (BWIM) and Structural Health Monitoring (SHM) systems applicable to major highway bridges. This system will improve the efficiency and accuracy of BWIM systems deployed and inspection procedures used in multi-lane bridges that operate under a range of traffic and weather conditions. The developed system is expected to improve the reliability and robustness of currently used BWIM or SHM methods through using probabilistic analysis approaches rather than deterministic solutions, real-time integrated sensor arrays, innovating sensing technologies, and cloud base analytics. The proposed BWIM-SHM system will be validated through the design, development, and implementation of the hybrid system on two major highway bridges in the Province of New Brunswick. This project will support NBDTI in developing and validating the accuracy and functionality of several advanced and integrated technologies applicable to a hybrid BWIM-SHM system. The proposed system would provide NBDTI and other transportation authorities a cost-effective, non-destructive, permanent, and convenient alternative to the current weigh-in-motions systems and simultaneously offer SHM functionalities for condition monitoring of critical bridges. Three research trainees will receive advanced training in specialized topics in bridge engineering focusing on load rating, bridge structural assessment, bridge dynamics, and numerical modelling. This proposal highlights initiatives to improve equity, diversity, and inclusion within the research team and throughout the training plan. This research will contribute to the existing body of knowledge across multiple disciplines including bridge engineering, numerical simulation, system identification, digital twining, and internet of things.

拟议项目将开发适用于主要公路桥梁的混合桥梁动态称重（BWIM）和结构健康监测（SHM）系统。该系统将提高在各种交通和天气条件下运行的多车道桥梁中部署的BWIM系统和检查程序的效率和准确性。开发的系统预计将通过使用概率分析方法而不是确定性解决方案，实时集成传感器阵列，创新传感技术和云基础分析来提高目前使用的BWIM或SHM方法的可靠性和鲁棒性。建议的BWIM-SHM系统将通过混合系统的设计、开发和实施在新玩法省的两座主要公路桥梁上进行验证。该项目将支持NBDTI开发和验证适用于混合BWIM-SHM系统的几种先进集成技术的准确性和功能性。拟议的系统将为NBDTI和其他交通当局提供一个具有成本效益的，非破坏性的，永久的，方便的替代目前的动态称重系统，同时提供SHM功能，用于关键桥梁的状态监测。三名研究学员将接受桥梁工程专业课题的高级培训，重点是额定载荷、桥梁结构评估、桥梁动力学和数值建模。该提案强调了在研究团队和整个培训计划中提高公平性，多样性和包容性的举措。这项研究将有助于跨多个学科的现有知识体系，包括桥梁工程，数值模拟，系统识别，数字缠绕和物联网。
