Assessment of seismic resistance of a traditionally-built farmhouse |
Sekundarni povzetek: |
In this thesis we have checked the earthquake resistance of a traditionally-built farmhouse in Spodnje Danje by using SAP2000 software. The first part of the thesis summarizes the requirements of the SIST EN 1998-3:2005 standard, which is intended to be used for seismic performance assessment and retrofit of existing buildings, and the procedures for the assessment of individual elements on the basis of three different failure mechanisms of masonry walls - sliding shear resistance, shear resistance due to formation of diagonal cracks and flexural resistance. In the second part of the thesis we have briefly described the design of the structure, the material and the modelling of the structure in SAP2000. We have constructed two models with the same structural systems. The only difference was, that the masses in model 1 have been defined at storey level, while in model 2 the masses have been computed automatically by the program on the basis of defined density of the wall and vertical load on the floors. Seismic demands, which were determined by modal response spectrum analysis, were compared with the capacities for each structural element, and thus earthquake resistance for individual elements as well as global earthquake resistance of the structure was evaluated. The comparison between the results shows that shear forces in the walls are very similar if calculated by using model 1 or 2, but the use of model 1 is less computationally demanding and provides transparent results. The results of the study show that the structure is incapable of resisting the design earthquake loads. |

V nalogi smo s pomočjo programa SAP2000 preverili potresno odpornost tradicionalno grajene kmečke hiše v Spodnjih Danjah. V prvem delu naloge smo povzeli zahteve standarda SIST EN 1998-3:2005, ki je namenjen za oceno obnašanja obstoječih stavb med potresom. V skladu z določili standarda smo za določitev potresne obremenitve elementov uporabili modalno analizo s spektri odziva. Nosilnost posameznih elementov smo preverili na podlagi treh možnih porušnih mehanizmov zidovja - strižne nosilnosti z zdrsom, strižne nosilnosti z nastankom diagonalnih razpok in upogibne nosilnosti. V drugem delu diplome smo na kratko opisali zasnovo zgradbe, material in modeliranje konstrukcije v programu SAP2000. Naredili smo dva modela z enakim modelom konstrukcijskega sistema, razlikovala sta se samo v tem, da smo pri modelu 1 celotno maso definirali na nivoju etaž, pri modelu 2 pa je program maso izračunal na podlagi specifične teže zidov in ploskovne obtežbe v horizontalnih elementih na višini etaž. Za oba modela smo določili obremenitev elementov zaradi potresne obtežbe ter jo primerjali z njihovo nosilnostjo. Na ta način smo ocenili potresno odpornost posameznih elementov ter tudi globalno potresno odpornost konstrukcije. Primerjava rezultatov analiz za oba modela pokaže, da so prečne sile v stenah zelo podobne ne glede na uporabljen model, vendar program bistveno hitreje izračuna obremenitve v elementih zaradi potresa v modelu 1. Rezultati obeh analiz kažejo, da stavba ni sposobna prevzeti projektne potresne obtežbe. |
