DIMENSIONING OF A BRIDGE FOR PEDESTRIANS AND CYCLISTS

Predmet diplomske naloge je statična analiza in dimenzioniranje mostu za pešce in kolesarje. Bistvo diplomske naloge je dimenzioniranje že obstoječega mostu po evropskih standardih EUROCODE. Posebnost mostu je v stropu in tleh, sestavljenih iz CLT (Cross Laminated Timber) plošč in štirih lepljeih nosilcev. Nosilci in plošča delujejo kot T-nosilec. Za podrobno analizo T-nosilca je bilo potrebno modelirati linijski element v interakciji s CLT ploščo. Ker v Evropi za dimenzioniranje CLT plošč še ne obstajo veljavni standardi, je bilo potrebno izpeljati porušne mehanizme CLT plošč. Most je osrednjega razpona 35 m in visi na dveh vrveh, ki delujeta kot verižnica. Že obstoječi most smo hoteli prilagoditi slovenskim standardom. Poleg mehanske odpornosti smo navedli še nekatere rešitve za komunalno opremljenost takšnih mostov. Navajamo tudi postopek za pridobitev ustrezne dokumentacije pred izgradnjo mostu.The subject of my diploma is the constructional analysis and dimensioning of a bridge for pedestrians and cyclists. The essence of this diploma is adjusting an existing bridge to suit the European EUROCODE standards. The special feature of the bridge is its ceiling and floor consisting of a CLT (Cross Laminated Timber) panel and four glued beams. Panel and beams function as a T-beam. The detailed analysis of a T-beam required modelling of a line-element in interaction with a CLT panel. Due to the lack of valid CLT panel modelling standards in Europe it was necessary to derive equations for failure mechanisms of CLT panels. The bridge has a central span of 35m and is suspended on two steal ties. Our goal was to adjust the existing bridge to suit the Slovenian standards. In addition to mechanical resistance, we have listed some other solutions for municipal equipment of such bridges. We also offer the procedure for obtaining the appropriate documentation before the beginning of the construction work on a bridge
