V okviru magistrskega dela je obravnavano protipotresno utrjevanje nosilne konstrukcije OŠ Riharda Jakopiča v Ljubljani. V prvem delu naloge je prikazan krajši pregled razvoja prvih predpisov za protipotresno gradnjo vse do danes veljavnih Evrokodov. Opisan je splošen postopek načrtovanja rekonstrukcije objekta od ocene obstoječega stanja na podlagi terenskih oz. laboratorijskih preiskav, potresne analize obstoječega stanja v skladu z veljavnimi predpisi ter načrtovanjem utrditvenih ukrepov. Pomemben del magistrskega dela je ocena potresne odpornosti obstoječe nosilne konstrukcije objekta na podlagi nelinearne statične potisne analize v programu 3Muri. Vhodni podatki za numerični model so bili pridobljeni na podlagi dostopne tehnične dokumentacije, poročil o izvedenih preiskavah ter lastnih neporušnih preiskavah. Na podlagi rezultatov potisnih krivulj ter največjih možnih pomikov in pospeškov, ki jih dobimo s programom 3Muri, je bilo ugotovljeno, da obstoječi objekt ne zadosti zahtevam potresne odpornosti glede na zahteve veljavnega protipotresnega standarda. V zadnjem delu je analiziran postopek utrjevanja nosilne konstrukcije z opisom nabora možnih utrditvenih ukrepov. Analizirali smo več različnih možnih ukrepov za povečanje potresne odpornosti z uporabo dodatnih jeklenih okenskih okvirjev, povečanjem deleža sten, armiranobetonskih ometov in FRCM (kompozitne tkanine v cementni matriki) utrditev ter preverili njihov vpliv na protipotresno odpornost stavbe. V zaključnem delu naloge sta bolj podrobno prikazani dve najbolj uspešni varianti za utrditev nosilne konstrukcije, s katerima objekt zadosti trenutno veljavnim predpisom o potresni gradnji v Sloveniji. The master thesis deals with the seismic strengthening of the load-bearing structure of the public primary school of Rihard Jakopič in Ljubljana. In the first part of the thesis, we made a brief overview of the regulation development for the seismic design in Slovenia. The thesis describes the procedure for the design of mitigation actions for the building from the assessment of the existing condition on the basis of the results of different testing methods, seismic analysis of the building in current state and design of restrengthening measures. An important part of the master thesis is the assessment of seismic resistance of the existing load-bearing structure of the building through non-linear seismic analysis provided by the software 3Muri. The input data for the numerical model were obtained on the basis of available technical documentation, investigation reports and our own non-destructive tests. Based on the results of the pushover capacity curves and the maximum displacements and accelerations obtained with the 3Muri program, it was determined that the existing facility does not meet current requirements for the seismic resistance. In the last part of this thesis, mitigation actions were analysed with a set of possible strengthening measures. For this purpose we analysed different measures such as using steel window frames, adding load-bearing walls, applying reinforced concrete plasters and FRCM (fibre reinforced cement matrix) and assess their impact on the seismic performance of the building. In the final part of the thesis two the most successful solutions for the strengthening that satisfies the currently valid seismic requirements in Slovenia are presented in more details.

V diplomski nalogi je izdelana ocena tveganja pri oskrbovanju s pitno vodo. Gre za vodovodni sistem na področju Trnovskega gozda. Zanimiva je predvsem njegova zgodovina gradnje, saj je bil grajen s pomočjo 4 držav. Oskrbovanje s pitno vodo pa je pri tem vodovodnem sistemu v celotni meri odvisen od delovanja trase tlačnega cevovoda od zajetja Skuk pa do vodohrana Predmeja. Zato je bila ocena tveganja izdelana predvsem za območje trase tlačnega cevovoda. Na podlagi razdelitve vodovodnega sistema na različne podsisteme, gradnike in sestavne dele je omogočena izdelava registra tveganj, katere namen je pomagati upravljavcu pri določanju ukrepov za izboljšanje delovanja in zmanjšanja tveganja. Metoda, ki je privzeta za oceno tveganja na vodovodnem sistemu Gora, je omogočila dobro ugotavljanje tveganj za različne nevarne dogodke, ki bi lahko ogrozili delovanje vodovodnega sistema. Na podlagi izdelanega registra tveganj bi lahko izdelali dobre preventivne ukrepe, ki bi pripomogli k večji varnosti obratovanja vodovodnega sistema. Pri analizi tveganj nam je s poznavanjem sistema pomagal upravljavec vodovodnega sistema Gora. The thesis produces a risk assessment of supplying drinking water. It focuses on a water supply system in the area of the Trnovo Forest. The building history of the forest is specially interesting, since it has been built with the help of 4 countries. The drinking water supply in this system is entirely dependent on the performance of the penstock route from the Skuk reservoir to the water storage Predmeja.Therefore, the risk assessment was made primarily on the penstock route area. Based on the distribution of the water supply system into different subsystems, building blocks and components, it is possible to create a register of risks, the purpose of which is to assist the operator in determining the measures and actions to improve performance and reduce risk. The method used for risk assessment in the water supply system Gora has allowed a good identification of risks for various hazardous events that could endanger the operation of the water supply system.Based on the produced risk register, the creation of preventive measures, that would contribute to greater operation safety of the water supply system, is possible. All results of the risk assessment were produced with the help of the operator of the water supply system.
