Evaluation of seismic resistance of a residential house in Ljubljana |
Sekundarni povzetek: |
The subject of the Thesis is seismic performance assessment of a residential masonry building located in Ljubljana. Firstly, different failure mechanisms of masonry walls, i.e. flexural mechanism, the sliding shear mechanism and shear mechanism characterized by formation of diagonal cracks, are presented and discussed. In the second part, the individual residential house is considered as a case study. Seismic forces were determined by the lateral force method of analysis, as it is defined in SIST EN 1998-1:2005. A model of each storey was developed in program SAP 2000 in order to assess internal forces in structural walls. Since in-situ tests of material characteristics were not available, which is quite common in practice, we assumed them from the literature. However, such approach yield results which are slightly more uncertain, since it is well known that the material strength of the masonry wall significantly affects the earthquake-resistance and even the collapse mechanism of the masonry wall and the entire structure. Finally, resistance of all individual elements and that of the building was checked. The results show that the building is not able to withstand design seismic actions, therefore strengthening measures are proposed and discussed. |

V diplomski nalogi je narejena ocena potresne odpornosti zidane konstrukcije. V prvem delu so obravnavani trije možni porušni mehanizmi za določevanje odpornosti nearmiranega zidu: upogibni mehanizem, strižni mehanizem z zdrsom ter strižni mehanizem z nastankom diagonalnih razpok. V drugem delu naloge obravnavamo individualno hišo. Potresne sile smo določili z metodo z vodoravnimi silami, pri čemer smo upoštevali potresno obtežbo, kot jo definira standard SIST EN 1998-1: 2005. Za določitev obremenitve zidov smo uporabili program SAP2000, s katerim smo izdelali poenostavljen etažni model stavbe. Materialne karakteristike zidu iz opečnih votlakov smo privzeli iz literature. Takšen pristop je precej običajen v praksi, če ni na voljo in-situ preiskav. Rezultati so tako nekoliko bolj negotovi, saj imajo materialne lastnosti zidu velik vpliv na nosilnost ter tudi na mehanizem porušitve elementa in konstrukcije. V zadnjem delu nalogu navajamo kontrole odpornosti posameznih elementov ter tudi kontrole odpornosti stavbe kot celote. Rezultati kažejo, da stavba ni sposobna prevzeti projektne potresne obtežbe, zato so opisani predlagani |
