Projektiranje cestnega mostu z leseno nosilno konstrukcijo : diplomska naloga

Hribernik, Matic (author), Lopatič, Jože (mentor)

Diplomska naloga obravnava statično analizo in dimenzioniranje mostu z leseno nosilno konstrukcijo, ki je namenjen cestnemu prometu. V nalogi so določeni glavni vplivi na mostno konstrukcijo, narejena je statična in modalna analiza v računalniškem programu Sofistik. Dimenzionirani so nosilni elementi mostu in njihovi priključki. Projektiranje je narejeno v skladu z evropskim standardom Evrokod, kjer so upoštevani parametri iz nacionalnega dodatka. Most, ki ga projektiramo ni resničen in smo si njegovo nosilno konstrukcijo zamislili na podlagi že obstoječih podobnih lesenih mostov. Lokacija mostu je izbrana na regionalni cesti v naselju Luče, kjer prečka reko Savinjo. Razpon mostu znaša 32 m, njegova širina pa 7 m. Primarna nosilna konstrukcija mostu sta dve razpori na obeh straneh mostu, na kateri je v temenu razpor z jeklenimi vešalkami obešen jekleni HEB profil. Preko jeklenega profila, ki predstavlja podporo na sredini razpona, poteka 8 vzdolžnih nosilcev, ki nosijo voziščno ploščo. Voziščna plošča je narejena iz pokonci obrnjenih lesenih moralov, ki so postavljeni prečno na vzdolžne nosilce in so med sabo povezani z mozniki. Obe razpori imata kraka povezana z jekleno vodoravno vezjo, zato se v podporah pojavi samo vertikalna reakcija. Razpori in vzdolžni nosilci so pravokotnega prereza in narejeni iz lepljenega lameliranega lesa kakovosti GL-36h, morali pa so iz lesa kvalitete D60.

• Title: Design of the road bridge with timber load-bearing structure

Abstract

The subject of thesis is static analysis and design of a timber bridge, with a structure that is designed for road transport. In the thesis we set out the main actions on the bridge and we made static and modal analysis with the computer program Sofistik. We also designed load-bearing elements and their connections. The design has been done in accordance with the European standard Eurocode, where the National Annex has been taken into consideration. The bridge which we have designed does not exist and we have conceived the load-bearing structure on the basis of already existing similar timber bridges. Location of the bridge was selected on the main road in the village Luče, where it crosses the river Savinja. Span of the bridge is 32 m and its width is 7 m. The primary load-bearing structure of the bridge consists of two struts on both sides of the bridge which supports steel HEB beam through vertical hangers. On top of the steel beam, which is in the middle of the span, takes place eight longitudinal timber beams, bearing timber deck. Timber deck is made of a wooden, upright facing planks that are positioned perpendicular to the longitudinal beams and are connected with dowels. Both struts are linked with steel cables and therefore there are only vertical reactions in supports. Struts and longitudinal beams are rectangular and made of glued laminated timber GL-36H, the planks are of timber D60.
