Abstract

Magistrska naloga obravnava statično in dinamično analizo mostu Renke, ki je bil zgrajen leta 1991 z namenom omogočanja prehoda ljudi iz naselja do železniške postaje na nasprotni strani reke Save. Danes so na mostu vidne poškodbe, vključno s preperelimi deskami, odpadanjem barve in rjavečimi jeklenimi elementi, ki so posledica pomanjkanja rednega vzdrževanja. Analiza mostu je narejena s pomočjo programa SCIA Engineer, z uporabo linearne in nelinearne teorije. Pri analizi so upoštevani standardi iz družine Evrokod 1, 2, 3, 7 in 8. Preverjeni so tako jeklena konstrukcija mostu kot tudi betonski temelji. Most je opisan kot viseči most, pri čemer se glavna jeklenica naslanja na dva pilona, ki sta postavljena na obeh straneh mostu in sta zasnovana v obliki črke A. Glavna jeklenica je sidrana v zaledje s težnostnim zidom in geotehničnimi sidri. Širina mostu znaša 1,62 m, glavni razpon meri 72 m, stranska razpona pa 15 m in 10 m. Na glavno jeklenico so simetrično pritrjene vešalke, ki zagotavljajo oporo glavnemu L-nosilcu in horizontalnemu povezju s hrastovimi deskami. Glavni cilj magistrske naloge je primerjava rezultatov analize mostu Renke med standardom JUS in sodobnim evropskim standardom Evrokod. Analiza kaže, da Evrokod v nekaterih primerih prinaša bistveno drugačne rezultate od standarda JUS, deloma tudi zaradi uporabe različnih materialnih parametrov. Ta primerjava omogoča boljše razumevanje vpliva standardov na varnost in zmogljivost mostu ter poudarja pomen uporabe aktualnih standardov pri načrtovanju in vzdrževanju infrastrukture.

Secondary title:	Static and dynamic analysis of the steel suspension bridge in Renke
Secondary abstract:	This master's thesis focuses on the static and dynamic analysis of the Renke Bridge, which was constructed in 1991 with the purpose of providing access to the railway station on the opposite side of the Sava River. Today the damages can be seen on the bridge, including weathered boards, peeling paint, and rusting steel elements, resulting from inadequate regular maintenance. The analysis of the bridge is carried out with the SCIA Engineer software, both linear and nonlinear theory. The analysis considers standards from the Eurocode 1, 2, 3, 7 and 8. Both the steel structure of the bridge as well as its concrete foundations are examined. The bridge is described as a suspension bridge, with the main cable supported by two pylons located on both side of the bridge, designed in the shape of the letter A. The main cable is anchored to the backstay with a gravity wall and geotechnical anchors. The bridge has a width of 1.62 meters, a main span of 72 meters, and side spans of 15 meters and 10 meters. Hangers are symmetrically attached to the main cable, providing support to the main L-beam and horizontal connections with oak boards. The main goal of this thesis is to compare the results of the Renke Bridge analysis between the JUS standard and the modern European Eurocode standard. The analysis reveals that Eurocode yields significantly different results from the JUS standard in some cases, partly due to the use of different material parameters. This comparison provides a better understanding of the standards' impact on the safety and performance of the bridge, emphasizing the importance of using current standards in the design and maintenance of infrastructure.
