Sekundarni naslov:	Analysis of suggested improovement of the precast concrete structure
Sekundarni povzetek:	The thesis focuses on the behaviour of the construction in question and how it is able to whitstand different combinations of vertical and horizontal loads. The decision for such analysis was based on the fact that such type of design is offered on the market and one is able to buy it. First part of the thesis focuses on the general use of precast concrete, when the use of such constructions is justified and what are the interactions between different construction elements. Joints and connections, which are very important in precast structures, are described in the second part. Third part of the thesis focuses on the structure which is, by its design, made of two different types of constructions. In the thesis I talk about left and right part of the construction. Left part of the object consits of two floors while the right part only has groundfloor. We can therefore talk about the stucture of two different levels of rigidity. Different respons to eartquake load is also expected. Software Tower 5.5 was used to analyse the structure. Modal analysis of primar structure was not possible because the software considered the structure to be labile. While examining the calculation of the manufacturer I came to the conclusion that some of the loads were not chosen correctly nor were they in accordance with Eurocode. Therefore we needed to improve the design and had done so with as little intervention possible. Calculation and modal analysis of improved structure was possible in accordance with Eurocode. The thesis does not focuse on dimensioning of elements. The primar structure is able to whitstand vertical loads. Our main point of interest was how much would the different types of constructions sway towards one another in case of an earthquake and would they collide. The calculation of the improoved design shows that the horizontal sways may be big enough and the constructions may collide. The thesis therefore shows that such combining of two different types of constructions in Slovenia is improper and that such constructions need considerable improovement.

Povzetek (ePrints):	Diplomsko delo obravnava obnašanje obstoječega montažnega objekta pod kombinacijami vertikalnih in horizontalnih obtežb. Osnova za odločitev za takšno analizo je dejstvo, da je takšno konstrukcijo možno kupiti na trgu. Prvi del naloge opisuje splošno uporabo prefabriciranega betona v različne namene, kdaj je le-ta upravičena in kakšni so medsebojni vplivi med posameznimi konstruktivnimi elementi. Drugi del je namenjen opisu vezi in povezav med elementi, ki so pri takšnih konstrukcijah nadvse pomembni. Tretji del opisuje objekt z nosilno konstrukcijo, ki je po svoji zasnovi iz dveh različnih tipov. V nalogi navajam levi in desni del konstrukcije. Levi del objekta je dvoetažen, desni del pa enoetažen. Govorimo torej o objektu, globalno, dveh različnih togosti in različnega obnašanja v primeru potresne obtežbe. Za modeliranje objekta sem uporabil program Tower 5.5, ki modalne analize osnovne konstrukcije ni izvedel, ker je bila konstrukcija labilna. Ob pregledu statičnega računa proizvajalca hale sem ugotovil, da nekatere obtežbe niso ustrezno izbrane, sploh pa na v skladu z Evrokodi. Z mentorjem sva se izboljšave lotila z najmanjšim možnim dodajanjem in spreminjanjem nekaterih nosilnih elementov. Statični račun in modalno analizo izboljšanega objekta je bilo potem možno izvesti v skladu z Evrokodi. S samim dimenzioniranjem se v nalogi ne ukvarjam. Osnovni objekt pod vertikalno obtežbo funkcionira, težava nastopi ob upoštevanju potresne obtežbe. Z mentorjem naju je najbolj zanimal pomik obeh tipov konstrukcije v vzdolžni smeri in ali ob nastopu potresne obtežbe lahko pride do trka objektov. Izkazalo se je, da so pomiki lahko tako veliki, da bi različni konstrukciji lahko trčili. Naloga torej dokazuje, da takšno kombiniranje različnih tipov montažne armirano betonske konstrukcije na območju Slovenije ni primeren in, da je takšen tip konstrukcije potreben večjih izboljšav in sprememb.
