Preverba nosilnosti lesenega ostrešja opuščenega gospodarskega objekta na Dolenjskem : diplomska naloga

Simončič, Manca (author), Saje, Drago (mentor)

V diplomski nalogi sem se osredotočila na preverbo statike lesenega ostrešja zapuščenega gospodarskega objekta, z namenom ocene njegove varnosti pred porušitvijo in varnosti za uporabo. Statični model ostrešja je bil narejen v računalniškem programu SAP2000. Nato je sledila analiza obtežb ter njihovih kombinacij za mejno stanje nosilnosti in mejno stanje uporabnosti glede na veljavne standarde in predpise. V analizi nisem zajela dinamičnih vplivov potresa, saj sem v nalogi preverila le stanje ostrešja, ne pa tudi ostalih delov stavbe. Mejno stanje nosilnosti konstrukcije ni preseženo, saj so napetosti v posameznih elementih ostrešja znotraj dovoljenih meja. Zaradi preseženih vrednosti povesov na nekaterih mestih je kritično mejno stanje uporabnosti. Na podlagi dobljenih rezultatov sem predlagala zamenjavo dotrajanih in strohnelih lesenih elementov ter uporabo špirovcev večjih dimenzij. S temi ukrepi bi zagotovila trajnost in varnost objekta v prihodnje.

• Title: Assessment of the structural capacity of the wooden roof of an abandoned building in Dolenjska : graduation thesis

Abstract

In my thesis, I focused on the structural analysis of the wooden roof structure of an abandoned agricultural building, with the aim of assessing its safety against collapse and safety for users. The structural model of the roof structure was created using the SAP2000 software. This was followed by an analysis of loads and their combinations for the ultimate limit state and serviceability limit state, according to relevant standards and regulations. The analysis did not include the dynamic effects of an earthquake. The ultimate limit state of the structure was not exceeded, as the stresses in individual elements of the roof truss were within permissible limits. However, the serviceability limit state is critical, as deflections were found to be excessive. Based on the results obtained, I recommended replacing the worn wooden elements, including rafters, as well as the removal and replacement of decayed parts. These measures would ensure the long-term durability and safety of the structure.
