20.500.12556/RUL-188378 Projektiranje armiranobetonske stavbe bolnice po trenutnih in prihajajočih standardih Evrokod magistrsko delo Design of a reinforced concrete hospital building according to current and future Eurocode standards Poseben izziv v potresnem inženirstvu predstavljajo objekti posebnega pomena, kot so zdravstvene ustanove, ki morajo ostati funkcionalne po potresu za zagotavljanje nujne medicinske pomoči. Prihajajoča nova generacija standardov Evrokod 2 in Evrokod 8 prinaša pomembne spremembe na tem področju, zato v tem magistrskem delu primerjamo postopek projektiranja nosilne konstrukcije armiranobetonske (AB) bolnišnice v Ljubljani, z mešanim konstrukcijskim sistemom, sestavljenim iz okvirov in stenastih jeder. Konstrukcija je v celoti projektirana in dimenzionirana za razred duktilnosti DCM po trenutno veljavnih standardih in DC3 po delovni različici nove generacije Evrokodov. Delo sistematično prikaže zasnovo nosilne konstrukcije, opis materialov in obtežb, analizo in dimenzioniranje medetažnih plošč ter potresno analizo in dimenzioniranje izbranih AB nosilnih elementov za prevzem potresnih vplivov. Osrednji del naloge vključuje tudi primerjavo dimenzij oz. količin armature nosilcev, stebrov in AB jedra, določenih po trenutno veljavni in novi generaciji Evrokodov. Nova generacija standarda Evrokod 8 uvaja nekatere spremembe, kot so nova definicija spektra pospeškov, posodobljene razrede duktilnosti ter spremenjen način določanja projektnih vplivov, vključno z ovojnicami upogibnih momentov in prečnih sil v stenah. V novi generaciji standarda so faktorje pomembnosti nadomestili faktorji zmogljivosti. Obravnavana konstrukcija spada v razred posledic CC3b, ki predstavlja najvišji razred posledic, obravnavan v novi generaciji standarda, in je projektirana za lokacijo Ljubljana ter tla tipa B. Za obravnavano konstrukcijo se faktor zmogljivosti zmanjša z 1,4 na 1,25, zaradi česar je bil potresni vpliv manjši. Posledično so bile pri okvirnih elementih ugotovljene manjše računsko potrebne količine armature. Pri stenah pa posodobljen način določanja projektnih vplivov vodi do večjih projektnih obremenitev, zato so bile kljub manjšemu potresnemu vplivu računsko potrebne količine armature primerljive. Vse ugotovitve veljajo izključno za obravnavani objekt in razred posledic CC3b ter izbrano lokacijo (tip tal B). A particular challenge in earthquake engineering is posed by buildings of special importance, such as healthcare facilities, which need to remain functional after an earthquake in order to provide essential medical services. The forthcoming new generation of Eurocodes 2 and 8 introduces significant changes in this field. Therefore, this master's thesis compares the structural design procedure for a reinforced concrete hospital building in Ljubljana, featuring a dual structural system composed of reinforced concrete frames and core walls. The structure was fully designed and dimensioned for ductility class DCM according to the currently applicable standards and for ductility class DC3 according to the draft version of the new generation of Eurocodes. The thesis systematically presents the structural design, material and load definition, structural analysis and design of the floor slabs, as well as a detailed global seismic analysis and seismic design of selected reinforced concrete structural. A central part of the study is the comparison of the dimensions and reinforcement quantities of beams, columns and the reinforced concrete core walls designed according to the current and new generations of Eurocodes. The new generation of Eurocode 8 introduces several important changes, including a new definition of the acceleration spectrum, updated ductility classes, and a modified approach to determining design actions, including bending moment and shear force envelopes in walls. Importance factors have been replaced by performance factors. The investigated structure belongs to consequence class CC3b, the highest consequence class considered in the new generation of the standard, and is designed for the location of Ljubljana and ground type B. For the investigated structure, the performance factor is reduced from 1.4 to 1.25, resulting in a lower seismic action. Consequently, smaller quantities of required reinforcement were obtained for the frame elements. For the walls, however, the modified procedure for determining design actions leads to higher design demands; therefore, despite the lower seismic action, the required reinforcement quantities remained comparable. The presented findings apply exclusively to the investigated building, consequence class CC3b, and the selected site category (ground type B). magistrska dela gradbeništvo Evrokod 8 Evrokod 2 potresnoodporno projektiranje armiran beton master thesis civil engineering Eurocode 8 Eurocode 2 design for earthquake resistance reinforced concrete true false false [U.
