Systems for weighing vehicles while they are in motion are in widespread use in many countries. The accuracy of these weigh-in-motion (WIM) systems is strongly influenced by the road profile and vehicle dynamics. Systems based on sensors that are embedded in the pavement or placed on top of the road surface can measure the axle load only for the fraction of a second for which the wheels are present on the sensor. An alternative to pavement WIM systems that increases the length of the load-sensitive element is to use an existing bridge as a weighing scale (Bridge WIM). A major test of a Bridge WIM system at a test site near the Arctic Circle is described in this paper. The test was conducted along-side a larger test of pavement WIM systems. A large number of trucks from random traffic were weighed statically and the results compared to those from the Bridge WIM system. The accuracy of the system is assessed in accordance with the COST 323 WIM specification, which provides a standardized method of accuracy classification. The Bridge WIM system is proven to perform satisfactorily and consistently for a wide range of temperatures in near-Arctic climatic conditions.

Vehicle-bridge interaction happens all the time on roadway bridges and this interaction performance carries much useful information. On one hand, while vehicles are traditionally viewed as loads for bridges, they can also be deemed as sensors for bridges' structural response. On the other hand, while bridges are traditionally viewed as carriers for vehicle weight, they can also be deemed as scales that can weigh the vehicle loads. Based on these observations, a broad area of studies based on the vehicle-bridge interaction have been conducted in the authors' research group. Understanding the vehicle and bridge interaction can help develop strategies for bridge condition assessment, bridge design, and bridge maintenance, as well as develop insight for new research needs.This book documents fundamental knowledge, new developments, and state-of-the-art applications related to vehicle-bridge interactions. It thus provides useful information for graduate students and researchers and therefore straddles the gap between theoretical research and practical applications.

Weigh-in-motion (WIM) is a process of measuring the dynamic tire forces of a moving vehicle and estimating the corresponding tire loads of the static vehicle. This collection of lectures from the International Conference on Weigh-in-Motion details applications such as: collection of statistical traffic data, support of commercial vehicle enforcement, roadway and bridge cost allocation, and traffic management.

Bridge Maintenance, Safety, Management, Life-Cycle Sustainability and Innovations contains lectures and papers presented at the Tenth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2020), held in Sapporo, Hokkaido, Japan, April 11–15, 2021. This volume consists of a book of extended abstracts and a USB card containing the full papers of 571 contributions presented at IABMAS 2020, including the T.Y. Lin Lecture, 9 Keynote Lectures, and 561 technical papers from 40 countries. The contributions presented at IABMAS 2020 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of maintenance, safety, management, life-cycle sustainability and technological innovations of bridges. Major topics include: advanced bridge design, construction and maintenance approaches, safety, reliability and risk evaluation, life-cycle management, life-cycle sustainability, standardization, analytical models, bridge management systems, service life prediction, maintenance and management strategies, structural health monitoring, non-destructive testing and field testing, safety, resilience, robustness and redundancy, durability enhancement, repair and rehabilitation, fatigue and corrosion, extreme loads, and application of information and computer technology and artificial intelligence for bridges, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of making more rational decisions on maintenance, safety, management, life-cycle sustainability and technological innovations of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including engineers, researchers, academics and students from all areas of bridge engineering.

Bridges are vital component of a country's transportation system and its economy. However, large number of ageing bridges are either structurally or geometrically deficient in some way. In recent years, the remaining life of ageing bridges, were calculated by detailed evaluation and damage assessment using structural health monitoring (SHM) techniques integrating bridge-weigh-in-motion (BWIM) systems. The field study of an existing BWIM system in Winnipeg, Manitoba was conducted on the Prototype Bridge. This work was extended to analysis and comparison of the algorithms adopted on the Prototype Bridge which provided deep insight in identifying the sources of error in BWIM systems. It was followed by a study on fatigue assessment of steel girder bridges. This research contributes by incorporating field measurements from BWIM system on the Prototype Bridge to estimate fatigue loading and damage assessment. In analytical phase, a simply supported beam subjected to moving and pulsating load was investigated for signal simulation and filtering in MATLAB. This was done as an initial exercise to understand dynamic effects of the load and its relevance to bridge natural frequency. This work was presented in a conference proceeding, attached in appendix. The experimental part of this work aims to identify sources of error in BWIM systems with the aid of the Model Bridge and verify area method, tested on the Prototype Bridge. The method was further investigated on the Model Bridge to obtain 95% confidence interval over real bridge BWIM testing. Model bridge structure was fabricated using polycarbonate. The model was designed to have natural frequencies like the Prototype Bridge. It was instrumented at two different locations with piezoelectric sensors for estimating velocity, transverse position, and class of model truck. It was instrumented with electrical strain gauges at three transverse locations for estimating Gross Vehicle Weight (GVW) of model truck. Video camera was used for verifying velocity profile. Author endeavored to establish relevance of long-term monitoring data obtained from BWIM to bridge evaluation. In this work it was proposed that SHM will add another level of inspection to CHBDC clauses and will improve the estimation of load carrying capacities of existing bridges.
