Design of the roof structure of family dwelling house with the analysis of existing timber structure and alternative variants

U diplomskome radu je provedena analiza postojeće drvene krovne konstrukcije obiteljske stambene zgrade te vrednovana prikladnost mogućih varijanti njene zamjene novim konstrukcijskim rješenjima. Krovište natkriva potkrovlje iznad prizemlja zgrade, koje se u postojećim okolnostima ne koristi, a treba ga prenamijeniti u stambeni prostor. Prenamjena ne predviđa bitne izmjene postojeće arhitekture i građevinske konstrukcije zgrade. Izmjene i dopune arhitektonskog rješenja pretpostavljaju promjenu pokrova i djelomičnu promjenu nagiba krovne plohe zbog zamjene postojeće južne fasade potkrovlja novim i višim ostakljenim zidom potkrovlja s pratećim nužnim promjenama građevinske konstrukcije. Rad je fokusiran na moguće izmjene i dopuna građevinskog projekta u dijelu u kojemu se to odnosi samo na drveno krovište jer je nužna zamjena konstrukcije u kojoj je vidljivo propadanja materijala zbog neprikladnog pokrova i dugotrajne izloženosti vlazi. Predmet provedenih analiza su moguće izmjene statičkog sustava krovišta. Primijenjeni su postupci uobičajeni u praksi projektiranja drvenih konstrukcija te priloženi odgovarajući proračuni i nacrti. Prikladnost tehničkih rješenja je vrednovana prema kriterijima iskaza količina materijala i izvedivosti rekonstrukcije uzimajući u obzir i izvođenje priključaka.In diploma thesis an analysis was conducted of the existing timber roof structure of the family residential building and evaluated the suitability of possible variants of its replacement with new structural solutions. The roof covers the attic above the ground floor of the building, which is not used in the present circumstances, and needs to be converted into a living space. The redevelopment does not foresee significant changes to the existing architecture and construction of the building. Changes and additions to the architectural solution presuppose a change of the roof and partial change of the roof surface slope due to the replacement of the existing southern facade of the attic with a new and higher glazed attic wall with the accompanying necessary changes of the building structure. The paper focuses on possible modifications and additions to constuction project in so far it only concerns the timber roof, since it is necessary to replace the structure in which material deterioration is visible due to inadequate cover and long exposure to humidity. The subject of the analysis is the possible changes to the static roofing system. Procedures common in the design of timber structures have been applied and appropriate calculations and plans have been provided. The appropriateness of technical solutions have been evaluated according to the bill of materials and feasibility of reconstruction, taking into account the execution of joints
