Previous work by the authors have shown that the acceleration response of a damaged beam subject to a constant moving load can be assumed to be made up of three components: ‘dynamic’, ‘static’ and ‘damage’. Therefore, appropriate filtering of the acceleration signal can be used to highlight the ‘damage’ component and quantify its severity. This paper builds on these findings to examine if the s...

Dual-function amplifiers are proposed for the first time herein enhancing capability of a scanning test vehicle bridges. To start, closed-form solutions derived dynamic responses amplifier-vehicle-bridge system with moving vehicle. Then, amplification factors amplifier and presented assessing bridge/vehicle vehicle/amplifier transmissibility. It was known that spectrum may be hindered extractin...

Abstract The suspension-type monorail (STM) is a new type of rail transit, currently developing rapidly in China. Due to its short construction duration and high terrain adaptability, STM can save large land resources. In particular, by supplementing the traffic systems medium-sized cities, contribute green tourism projects. However, no systematic study devoted transit system China, there still...

With rapid industrial development, the overloading of bridges caused by heavy multi-axle vehicles has become a critical problem worldwide. This work conducts performance-based evaluation for tied-arch subjected to vehicles, and prediction function dynamic impact factor (DIF) is proposed considering bridge frequency, vehicle speeds, road quality level. Specifically, main parameters affecting res...

Recent collapses and malfunctions of European bridges threatened the service conditions road networks pointed out need for robust procedures to mitigate impact material degradation overloading existing bridges. Condition assessment remains a challenging task, which could take advantage cost-effective reliable inspection strategies. The advances in sensors as well Information Communication Techn...

Paper presents a study about dynamic effects obtained from the dynamic load testing of the city highway bridges in Latvia carried out from 2005 to 2012. 9 prestressed concrete bridges and 4 composite bridges were considered. 11 of 13 bridges were designed according to the Eurocodes but two according to the previous structural codes used in Latvia (SNIP 2.05.03-84). The dynamic properties of the...

The paper considers the influence of the surface profile on the dynamic amplification of a simply supported bridge when subject to a quarter car vehicle model. The effect of the profile irregularities on the bridge dynamic amplification is characterized with a ‘response surface’ giving dynamic amplification due to a 'unit ramp' at any location. Even though the dynamic interaction problem is non...

This paper describes the procedures for development of signal analysis algorithms using artificial neural networks for Bridge Weigh-in-Motion (B-WIM) systems. Through the analysis procedure, the extraction of information concerning heavy traffic vehicles such as weight, speed, and number of axles from the time domain strain data of the B-WIM system was attempted. As one of the several possible ...
