Bridge weigh-in-motion systems use instrumented bridges or culverts to weigh vehicles as they pass over the structures. They also provide data to allow the calculation of several bridge performance indicators. The article starts with the basics of a bridge weigh-in-motion system and briefly describe ...

The dynamic component of bridge traffic loading is commonly taken into account with a Dynamic Amplification Factor (DAF)—the ratio between the dynamic and static load effects on a bridge. In the design codes, this factor is generally more conservative than in reality. Recently a new method of cal- c ...

Optimalno upravljanje mostov, ki vključuje stroške vzdrževanja, potencialna tveganja in vzdrževanje funkcionalnosti, zahteva natančne informacije o stanju konstrukcij. Eden od ključnih kazalnikov obnašanja je konstrukcijska varnost mostu, ki zahteva poglobljeno poznavanje prometnih obremenitev in nj ...

This study describes the development and testing of a railway bridge weigh-in-motion (RB-WIM) system. The traditional bridge WIM (B-WIM) system developed for road bridges was extended here to calculate the weights of railway carriages. The system was tested using the measured response from a test br ...

As part of the reconstruction of a multi-span viaduct on a Slovenian highway, a permanent remote monitoring system with over 200 sensors was established. Several parameters are monitored on different parts of the viaduct by means of temperature sensors, accelerometers, strain gauges, long-gauge defo ...

Uneven road surfaces are the primary source of excitation in the dynamic interaction between a bridge and a vehicle and can lead to errors in bridge weigh-in-motion (B-WIM) systems. In order to correctly reproduce this interaction in a numerical model of a bridge, it is essential to know the magnitu ...

Okoljevarstvene zahteve in zakonodajno okolje narekujeta velike spremembe v mobilnosti, ki bodo v prihajajočih letih močno povečale delež hibridnih ter predvsem električnih vozil. Ena glavnih razlik teh pogonov v primerjavi s konvencionalnimi je drugačen način delovanja, kot je nenadna prekinitev in ...

Real contact area is a challenging phenomenon in tribology, where despite established theoretical models, detailed experimental studies are still lacking. This work is focused on the evolution of the real contact area of multi-asperity steel contacts during sliding, by using sub-micron characterisat ...

In this study we evaluated the tribological performance of polypropylene composites with wood-flour fillers obtained as a by-product from the wood-processing industry, which were based on unrecycled and recycled polypropylene polymer matrices. The mechanical properties of polypropylene-wood composit ...
