Secondary title: Design of load-bearing structural elements made of cross laminated timber
Secondary abstract: In the past years, timber has become a cutting-edge product, but it has not achieved the limits of its evolution. The belief that timber can be used solely for the construction of holiday houses, garden sheds, and other functional facilities is proving to be obsolete. Nowadays, both public and private timber constructions can compete with the most challenging building structures. What enhanced the development of timber was the invention of cross laminated timber; a construction element that allows for highly complicated and demanding architectural and constructional building designs. This graduation thesis presents a design of a cross laminated timber panel construction in a seismic area. First, the thesis highlights the advantages of timber constructions in terms of sustainable development. It goes on to describe cross laminated wooden panels, which have more uniform and better mechanical properties than one-way laminated timber elements. For the structural design of cross laminated timber panels, the HOBS (‘Homogenised, Orthotropic plane stress Blass reduced cross Section’) method was used, as proposed by Blass and Fellmoser. The design of the load-bearing construction elements made of cross laminated timber was based on an architecture student’s blueprints of a student residence halls. The modelling of the construction was conducted by the Sofistik software, which is used for basic limit states and seismic state. The crucial load-bearing elements and connectional joints were designed for the ultimate limit state. Service limit state check was performed by controls for deflection of timber panels and the displacement of flooring during seismic activity. A simplified calculation, adhering to the standard SIST EN 1995-1-2 and based on a reduced crosssection method, was used to verify the construction's compliance with the fire safety regulations. The thesis ends with a description of preservational methods for timber construction.

Abstract (ePrints): Les se je v zadnjih letih razvil v visokotehnološki izdelek, katerega meje razvoja še zdaleč niso dosežene. Miselnost, da je les uporaben le za gradnjo počitniških hiš, vrtnih lop in podobnih pomožnih objektov, z razvojem postaja del preteklosti. Danes les oziroma lesena gradnja lahko konkurira najzahtevnejšim izvedbam objektov, tako individualnega kot javnega značaja. K temu je veliko pripomogla iznajdba konstrukcijskih elementov iz križno lepljenih lesenih panelov, s katerimi lahko rešujemo zelo zahtevne in kompleksne konstrukcijske in arhitekturne zasnove objektov. V diplomski nalogi je predstavljeno projektiranje konstrukcije iz križno lepljenih lesenih plošč na potresnem območju. V začetku diplomske naloge so opisane prednosti gradnje lesenih stavb z vidika trajnostnega razvoja. Sledi predstavitev križno lepljenih lesenih plošč, ki izkazujejo mnogo bolj enakomerne in boljše mehanske lastnosti kot enosmerno lepljeni leseni elementi. Predstavljena je HOBS metoda projektiranja konstrukcij iz križno lepljenih lesenih plošč, ki sta jo predlagala Blass in Fellmoser (»Homogenised, Orthotropic plane stress Blass reduced cross Section method«). Projektiranje nosilnih elementov konstrukcije iz križno lepljenih plošč je predstavljeno na idejnem načrtu študentskega doma, katerega načrte je pripravil študent arhitekture. Modeliranje konstrukcije je bilo izvedeno s pomočjo programskega orodja Sofistik za osnovna projektna stanja in potresno situacijo. Dimenzionirani so izbrani kritični nosilni elementi in spoji za mejno stanje nosilnosti. Kontrola mejnega stanja uporabnosti je bila izvedena s kontrolo povesov plošč in kontrolo etažnih pomikov konstrukcije zaradi potresne obtežbe. Požarno zaščito konstrukcije smo preverili s poenostavljenim računskim postopkom v skladu s standardom SIST EN 1995-1-2 na podlagi reduciranega prereza. Končamo z zaščito lesenih konstrukcij.
