1072. Using weigh-in-motion data to determine bridge dynamic amplification factorJan Kalin, Aleš Žnidarič, Maja Kreslin, 2015, published scientific conference contribution Abstract: The dynamic component of bridge traffic loading is commonly taken into account with a Dynamic Amplification Factor (DAF) - the ratio between the maximum dynamic and static load effects on a bridge. In the design codes, this factor is generally higher than in reality. While this is fine for new bridges that must account for various risks during their life-time, it imposes unnecessary conservativism into assessment of the existing well defined bridges. Therefore, analysis of existing bridges should apply more realistic DAF values. One way of obtaining them experimentally is by bridge weigh-in-motion (B-WIM) measurements, which use an existing instrumented bridge or culvert to weigh all crossing vehicles at highway speeds. The B-WIM system had been equipped with two methods of obtaining an approximation to the static response of the. The first method uses the sum of influence lines. This method relies on accurate axle identification, the failure of which can have a large influence on the DAF value. The other method uses a pre-determined low-pass filter to remove the dynamic component of the measured signal; however an expert is needed to set the filter parameters. A new approach that tries to eliminate these two drawbacks has been developed. In this approach the parameters for the filter are determined automatically by fitting the filtered response to the sum of the influence lines. The measurement of DAF on a typical bridge site agrees with experiments performed in the ARCHES [1] project: dynamic amplification decreases as static loading increases.

1080. Extinction risk alert: evaluating conservation trends for the Golden-dimpled Ground Beetle (Carabus clatratus auraniensis J. Müller, 1903) in Western BalkansAndreja Brigić, Lea Ružanović, Mihaela Kristina Mlinarić, Snježana Vujčić-Karlo, Toni Koren, Al Vrezec, Andrej Kapla, 2025, original scientific article Abstract: Due to extensive habitat loss and specialised ecological niche, the Golden-dimpled Ground Beetle (Carabus clatratus) became a locally extinct species with fragmented distribution throughout Europe. The subspecies C. clatratus auraniensis J. Müller, 1903 was described from the Vrana Lake in the Mediterranean biogeographical region of Croatia. This study aims to: assess conservation status of C. clatratus auraniensis in the Western Balkans through a chronogeonemy analysis; evaluate habitat suitability at the type locality by analyzing historical land use changes; and determine the effectiveness of protected area networks in ensuring the long-term survival of the species in core area of its distribution in Western Balkans. The chronogeonemy analysis reveals the extinction of C. clatratus auraniensis in the Mediterranean biogeographical region, including in its type locality. This is most likely caused by land use changes such as ongoing habitat degradation and wetland drainage, primarily driven by urbanisation and agriculture. However, the gap analysis indicated a good coverage by protected areas, contradicting previous results. The protected areas were established after the subspecies extinction and therefore have no impact on its conservation success. This indicates that gap analysis must be combined with other methods, e.g. chronogeonemy analysis, in order to detect real-time conservation trends. The conservation status of C. clatratus auraniensis in the Continental biogeographical region is stable, with continuous occurrence since the late 19th century and an increase in records in the last three decades, even with long dispersal records (e.g. Mura River in NE Slovenia). Records increase are linked to large well-preserved semi-natural wetlands along the Sava, Drava and Danube rivers, reflecting the subspecies’ good prospects. Reintroduction into protected areas in the Mediterranean region of Croatia could be a viable strategy to support the survival of this subspecies, enhancing the conservation prospects for rare C. clatratus in Europe.
