Abstract
Magistrska naloga zajema postopek projektiranja lesenega razglednega stolpa. Stolp je umeščen na vrh hriba Javornik nad Črnim Vrhom in meri v višino 29,8 m. Primarno vertikalno nosilno konstrukcijo stolpa predstavljajo štirje zunanji in štirje notranji leseni stebri pravokotnega prečnega prereza, ki so na nivojih etaž povezani z zunanjimi in notranjimi prečnimi lesenimi nosilci. Horizontalno stabilnost objekta zagotavljamo z zavarovalnimi jeklenimi povezji, z jeklenimi diagonalami. Diagonale so vgrajene po zunanjem obodu stolpa. Stolp ima trinajst vmesnih etaž na katerih so stopniščni podesti. Na podeste so pritrjene stopniščne rame preko katerih je urejena vertikalna komunikacija do vrhnje štirinajste etaže, kjer imamo prostorno razgledno ploščad. Nosilna konstrukcija stolpa je projektirana in dimenzionirana upoštevaje sistem standardov Evrokod in mednarodni standard ISO 12494. V nalogi je sistematično predstavljena zasnova nosilne konstrukcije, analiza vplivov, postopek dimenzioniranja lesenih nosilnih elementov in njihovih karakterističnih spojev ter dimenzioniranje armiranobetonske temeljne plošče. Analiza vplivov na konstrukcijo je razdeljena na stalne in spremenljive vplivi. Pri spremenljivih vplivih smo upoštevali tudi obtežbo ledu, saj se je na tem območju v preteklosti že pojavil žledolom. Glavni poudarek naloge je na dimenzioniranju primarnih nosilnih elementov konstrukcije ter dimenzioniranju spojev glavnih nosilnih elementov konstrukcije. S pomočjo računalniškega programa Tower smo izvedli vse kontrole napetosti in stabilnosti posameznih elementov konstrukcije, v nalogi pa smo dimenzionirali samo najbolj obremenjene elemente pri merodajnih obtežnih kombinacijah. Prikazani so tudi postopki dimenzioniranja sekundarnih nosilnih elementov konstrukcije ter dimenzioniranje armiranobetonske temeljne plošče.

Title:Design of timber lookout tower on Javornik hill above Črni Vrh
Abstract:
The master´s thesis covers the process of designing a timber lookout tower. Tower is located at the top of Javornik hill above Črni Vrh and is 29,8 m tall. The load-bearing vertical structure of the building consists of four outer and four inner timber columns. All columns have a rectangular cross – section and are connected with timber crossbars in the levels of each floor. Horizontal stability of the building is ensured with bracing system with steel tension rods, which is installed around the outer perimeter of the tower. The tower has thirteen intermediate floors with platform, which connects staircase and lead to the highest forteenth floor, where is a spacious viewing platform. The load bearing structure of the tower is designed and dimensioned according to Eurocode system and international standard ISO 12494. The master´s thesis systematically presents the design proces of the load bearing structure elements, analysis of actions and environmental influences, the process of dimensioning timber load- bearing elements and their characteristic joints and designing of the reinforced concrete base plate. Analyzes of actions on the construction are divided into permanent and variable actions. In terms of variable actions we also took into account the weight of ice, as this environmental influence has already acurred in this area in the past. The emphasis of the master´s thesis is on the dimensioning of the primary load- bearing elements and the dimensioning of the joints. All tension and stability checks were made with computational program Tower. In the assignment were dimensioned only the elements with maximal internal forces in the relevant load combination. There were also dimensioned the secondary load – bearing elements of the strucutre and the reinforced concrete base plate.

Keywords:timber lookout tower, computational model, dimensioning of load-bearing elements, dimensioning of characteristic connections, dimensioning of base plate
