20.500.12556/DKUM-47802 DIMENZIONIRANJE GLAVNEGA DELA JEKLENEGA ŽELEZNIŠKEGA MOSTU KELANIYA BRIDGE NA ŠRILANKI DIMENSIONING OF THE MAIN PART OF THE STEEL RAILWAY KELANIYA BRIDGE ON SRI LANKA V magistrskem delu je predstavljeno preddimenzioniranje glavnega dela jeklenega paličnega železniškega mostu Kelaniya Bridge na Šrilanki z vijačenimi spoji po standardu Evrokod. Most, skupne dolžine 262,90 m, je sestavljen iz treh delov: iz jeklenega pristopnega mostu, glavnega mostu in armiranobetonskega pristopnega mostu. Glavni del mostu je sestavljen iz treh enakih podsistemov, razpon ene jeklene palične mostne konstrukcije meri 51,70 m. Poudarek leži na dimenzioniranju na utrujanje, zato so v tekstu podane tudi osnove utrujanja jekla. Dimenzioniranje mostu na utrujanje je izvedeno na podlagi dokaza s faktorji ekvivalentnih poškodb z obtežnim modelom LM71. Most je prav tako dimenzioniran na mejno stanje nosilnosti, kjer sta med drugim prikazana dokaz stabilnosti po teoriji drugega reda z upoštevanjem globalnih in lokalnih nepopolnosti ter dokaz s pomočjo metode nadomestnega tlačnega elementa. Na mejno stanje nosilnosti je dimenzionirana tudi spodnja konstrukcija z globokim temeljenjem. Ob koncu je prikazana primerjava med izkoriščenostmi prerezov konstrukcije po mejnem stanju nosilnosti in utrujanja. The master thesis deals with the dimensioning of the main part of the steel truss railway Kelaniya Bridge in Sri Lanka with bolted joints according to the Eurocode standard. The total length of the bridge is 262,90 m. The bridge consist of the following three parts: an entry steel bridge, the main part of the bridge and an entry reinforced concrete bridge. The main part of the bridge includes three steel truss structures with a span of 51,70 m each. The thesis is focused on the design of the steel truss structure for a fatigue resistance. For this purpose, a historical and technical background of the fatigue is explained. The design of the bridge for fatigue is made with damage equivalent factors based on the load model LM71. The bridge is also designed for the ultimate limit state, giving the global analysis and the dimensioning of the structure, based on the second order effects with the consideration of the global and local imperfections, as well as the structure check with the equivalent column method. In addition the lower structure with a deep foundation is designed for the ultimate limit state. The comparison between different levels of exploitation of the structure’s cross sections, based on the ultimate limit state and the fatigue calculation, is given at the end of the thesis. gradbeništvo jeklene konstrukcije železniški most analiza dimenzioniranje utrujanje civil engineering steel structures railway bridge structural analysis dimensioning fatigue true true false [R.
