Experimental study on wire breakage detection by acoustic emission

Limin SUN, Ji QIAN

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4,   Pages 503-509 doi: 10.1007/s11709-011-0132-8

Abstract: In the experiments, the attenuation laws of waveform amplitudes were discussed based on stress wave propagationFinally, based on the waveform attenuation laws and the linear position method, the amplitude and energyillustrated that the stress wave from different sources has a different frequency spectrum, and the amplitude attenuationfactor varied with the stress wave frequency; high frequency waves had a greater attenuation factor.and thus, the wire breakage signal can be distinguished from the other source by comparing the non-attenuation

A practical multi-lane factor model of bridges based on multi-truck presence considering lane load disparities

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 4,   Pages 877-894 doi: 10.1007/s11709-021-0756-2

Abstract: Many bridge design specifications consider multi-lane factors (MLFs) a critical component of the traffic load model. Measured multi-lane traffic data generally exhibit significant lane disparities in traffic loads over multiple lanes. However, these disparities are not considered in current specifications. To address this drawback, a multi-coefficient MLF model was developed based on an improved probabilistic statistical approach that considers the presence of multiple trucks. The proposed MLF model and approach were calibrated and demonstrated through an example site. The model sensitivity analysis demonstrated the significant influence of lane disparity of truck traffic volume and truck weight distribution on the MLF. Using the proposed approach, the experimental site study yielded MLFs comparable with those directly calculated using traffic load effects. The exclusion of overloaded trucks caused the proposed approach, existing design specifications, and conventional approach of ignoring lane load disparity to generate comparable MLFs, while the MLFs based on the proposed approach were the most comprehensive. The inclusion of overloaded trucks caused the conventional approach and design specifications to overestimate the MLFs significantly. Finally, the benefits of the research results to bridge practitioners were discussed.
