Abstract:Magistrsko delo obravnava primerjalno numerično analizo potresnega odziva večetažne armiranobetonske stavbe z dvema različnima stropnima konstrukcijama: popolnoma monolitno armiranobetonsko ploščo ter montažno stropno konstrukcijo iz predizdelanih votlih betonskih plošč. Primerjalna analiza je bila izvedena v programu RFEM 6 z uporabo linearno elastične potresne analize s spektri odziva, skladno z zahtevami standarda Evrokod 8, ob upoštevanju linearno elastičnih materialnih modelov, teorije prvega reda (geometrijsko linearni pristop) ter Reissner-Mindlinove teorije plošč. Osrednji cilj je bil preučiti, v kolikšni meri mehanske lastnosti in robni pogoji dveh stropnih konstrukcijskih rešitev vplivajo na potresni odziv konstrukcije, zlasti na rezultate modalne analize, globalno togost ter na razvoj notranjih statičnih količin v stenah, ob ohranitvi enake mase konstrukcij. Izdelana sta bila dva numerična modela: prvi s tipsko monolitno AB-stropno konstrukcijo, drugi pa z montažno stropno konstrukcijo iz predizdelanih votlih betonskih plošč. Rezultati analize, izvedene v okviru magistrskega dela, so pokazali, da sta večja statična nedoločenost in nižja ravninska togost stropne konstrukcije iz predizdelanih votlih betonskih plošč vodili do daljših nihajnih časov, večjih pomikov, rahlih sprememb nihajnih oblik ter povečanja upogibnih momentov in prečnih sil v stenah ob dosledno nekoliko nižjih osnih silah.

Title:Comparative numerical analysis of the influence of a monolithic and a precast hollow core slab on the seismic response of a reinforced concrete structure
Abstract:This master's thesis presents a comparative numerical analysis of the seismic response of a multi-storey reinforced concrete building with two different floor systems: a fully monolithic reinforced concrete slab and a precast floor system composed of hollow-core concrete slabs. The comparative analysis was carried out using the RFEM 6 software, applying a linear elastic response spectrum method in accordance with the requirements of Eurocode 8. The analysis was based on linear elastic material models, first-order theory (geometrically linear approach), and the Reissner–Mindlin plate theory. The main objective was to examine the extent to which the mechanical properties and numerical boundary conditions of the two floor systems affect the seismic response of the structure, particularly in terms of modal analysis results, global stiffness, and the development of internal forces in the walls, while maintaining equal structural mass in both models. Two numerical models were created: the first with a typical monolithic RC floor system, and the second with a precast floor system composed of hollow-core concrete slabs. The results of the analysis performed within the scope of this thesis showed that greater static indeterminacy and lower in-plane stiffness of the precast floor system led to longer natural periods, increased displacements, slight changes in mode shapes, and an increase in bending moments and shear forces in the walls, while axial forces were consistently slightly lower.
