    Götaälvbron: Töjningsmätningar för kalibrering av beräkningsmodell2015Report (Other academic)
    Abstract [en]

    The Götaälv Bridge in Gothenburg was instrumented with strain gauges in April 2015. This report is a presentation of the measurements performed until 29 April. The measurements were performed by personnel from the Division of Structural Engineering and Bridges at KTH. The project was commissioned by the City of Gothenburg – Traffic & public transport authority through ÅF Infrastructure AB and performed in collaboration with researchers from the Division of Structural Engineering at Chalmers University of Technology.

    The monitoring system comprised 23 strain gauges divided between two areas. One between support 13 and 14 at the South Viaduct and one between support III and IV at the elevated river part. Measurements were performed at four arranged bridge openings and a calibration monitoring using two trucks with known weights. Continuous measurement was also performed during the afternoon Tuesday 28 April.

    For the bridge openings, stresses up to 5,6MPa were recorded on the elevated river part. The recorded stresses are lower than those caused by the ordinary traffic in the instrumented locations.

    The calibration measurements were performed during night using two trucks with weights of 25,0 tons and 25,1 tons, respectively. Together, they caused maximum recorded stresses of 15,4MPa for the South Viaduct and 16,8MPa for the elevated river part. Associated stress ranges were 19,4MPa and 19,8MPa, respectively. The largest values were recorded in the gauges located close to the mid spans.

    Stress range spectra are presented for the short term continuous measurement. The daily traffic gives in general lower stress ranges than the trucks used for the calibration. A large portion of the cycles are distributed over small stress ranges.

    For the gauges on the elevated bridge part, the analyses show a significant influence of dynamics on the results.

    Långtidsmätningar av töjningar och accelerationer på Nya Årstabron 2013-08-21 till 2014-01-202014Report (Other academic)
    Abstract [sv]

    Denna rapport har sammanställts med det primära målet att visa resultat för de KTH-sensorer som är installerade på Nya Årstabron. Mätningen har pågått sedan bygget av bro 2003 men denna rapport fokuserar på resultat från perioden 2013-08-21 till 2014-01-20. Tidigare mätresultat finns redovisade i årliga rapporter från KTH-Brobyggnad.

    Mätsystemet består av 21 sensorer för töjningsmätning, 1 LVDT sensor för deformations-mätning, samt 6 accelerometrar. I dagsläget fungerar 19 utav de ursprungliga 21 trådtöjnings-mätarna. LVDT:n kan fungera korrekt men överensstämmer inte helt resultatmässigt med sensor BK5, som är ingjuten i betongen där LVDT:n är monterad på betongytan. Alla 6 accelerometrar fungerar utmärkt.

    Systemet har varit avstängt under delar av 2012 och 2013 då Trafikverket stängde av den fasta Internetuppkopplingen vid årsskiftet 2011-2012. Sedan augusti 2013 har KTH kontakt med mätutrustningen via ett trådlöst modem.

    Generellt kan sägas att en jämförelse med tidigare mätta värden inte visar på någon förändring i brons beteende. Dock, en viss tendens till förändrade töjningsnivåer i flänsarna kan iakttagas och en fortsatt studie av dessa är att rekommendera.

    Det avancerade mätsystemet som den nya Årstabron har kan även nyttjas för att identifiera brons egenfrekvenser, modformer, dämpkvoter, krympning/krypning, sprickbildning samt andra långtidseffekter. Detaljerad information om specifika tågkonfigurationer är också möjlig att erhålla, innefattande tågets fart, axellaster och axelavstånd.
