Projektiranje lesene brvi čez avtocesto A2 na odseku Kranj vzhod - Brnik : diplomska naloga

Zupanc, Maša (author), Lopatič, Jože (mentor)

Diplomska naloga obravnava projektiranje lesene brvi za pešce in kolesarje čez avtocesto A2 na odseku Kranj vzhod – Brnik. V izhodišču so predstavljene osnovne značilnosti lesenih mostov ter okvirna navodila za projektiranje kolesarskih površin. V nadaljevanju je predstavljena zasnova predmetnega mostu ter glavne značilnosti izbranih materialov. Diplomska naloga nato obravnava glavne obtežbe na konstrukcijo, njihove kombinacije in razporeditve na štirih med seboj povezanih modelih, pripravljenih s programom SAP2000. Na podlagi dobljenih notranjih sil je bilo nato izvedeno dimenzioniranje posameznih elementov in njihovih priključkov. Za primarno nosilno konstrukcijo brvi sta bila izbrana dva lesena lepljena nosilca dimenzij 40/180 cm trdnostnega razreda GL28h. V prečni smeri primarna nosilca povezuje 23 jeklenih okvirov kvalitete S355, pozicioniranih na medsebojni razdalji 3 m. V horizontalni smeri z jeklenim vroče valjanim profilom HEB200, v vertikalni smeri pa z dvema profiloma HEB200. Za prevzem obremenitev v prečni smeri so, v kombinaciji z jeklenimi nosilci, predvidene jeklene diagonale premera 20 mm in kvalitete S235. Sekundarno nosilno konstrukcijo predstavlja pet lesenih lepljencev, dimenzij 24/26 cm, pozicioniranih na medsebojni osni razdalji 0,59 m. Povozno oz pohodno površino sestavljajo podnice iz hrastovega lesa prečnega prereza 20/12 cm.

• Title: Design of timber footbridge across highway A2 on the section Kranj east - Brnik

Abstract

This thesis contains the design of footbridge for pedestrians and cyclists that spans over highway A2 on the section Kranj east – Brnik. The introduction contains general characteristics of timber bridges and basic instructions to designing cycle-friendly infrastructures. In the following chapters present the basic design of the footbridge and the characteristics of the various materials used. The thesis then elaborates the main loads on the structure, their combinations and their application on the four interconected models prepared with computer program SAP2000. As a product of static and modal analysis, the internal forces were used in the proces of constructing the main elements of the bridge and their connestions. For the primary load-bearing structure of the footbridge, two glued laminated timber beams of dimensions 40/180 cm were chosen. In the transverse direction, the two primary beams are connected by 23 steel frames of quality S355, positioned at a mutual distance of 3 m. Primary beams are connected with a steel profile HEB200 in the horizontal direction and with two steel profile HEB200 the vertical direction. In the transverse direction steel profiles are connected with steel diagonals φ20 and quality S235. The secondary load-bearing structure of the bridge is represented by the five glued laminated timber beams, of dimensions 24/26 cm, positioned at a mutual axial distance of 0,59 m. The surface of the footbridge consists of oak wood with dimensions 20/12 cm.
