Abstract
This master thesis deals with a detailed investigation of the influence of layered casting and phased construction on the stressing due to self-weight. The investigations are carried out with finite element analysis and in particular, the occurring stressing due to self-weight without and with regard to the casting and construction process are compared. The investigations were done for two different cases. The first case is a massive concrete foundation which is casted in layers. Although the layers are placed fresh-in-fresh on top of each other, the casting process lasts overall that long that the lower layers developed already significant stiffness before the upper layers do even set. The investigations in this case focus therefore on the question how the resulting differences on the present stiffness over the height may cause significant changes in the horizontal stressing due to the settlement due to self-weight. The second case is a jointless building construction with two building cores and several floors over the height. The floors are cast subsequently whereby the increasing self-weight with ongoing construction process causes a subsidence cavity in which the whole structure settles. And by this the build-up of a bending moment over the entire height of the building with a tensile force in the foundation slab is presumed.
Abstract (croatian)
Tema ovog diplomskog je istražiti utjecaje betoniranja u slojevima i fazne gradnje na naprezanja uzrokovana vlastitom težinom konstrukcija. Istraživanja su provedena analizom konačnih elemenata, a posebno su se uspoređivala naprezanja uzrokovana vlastitom težinom gdje su utjecaji prilikom betoniranja i samog procesa izgradnje uspoređeni. Ispitivanje je provedeno na dva različita slučaja. Prvi slučaj je slučaj masivnog betonskog temelja gdje se betoniranje vrši u slojevima. Iako su slojevi lijevani jedan na drugi, cijeli proces traje sve dok donji sloj ne razvije dovoljnu krutost prije nego li se gornji sloj slegne. U fokusu ovog istraživanja je istražiti kako rezultirajuće razlike na postojećoj krutosti po visini mogu uzrokovati značajne promjene u horizontalnim naprezanjima kao posljedica slijeganja zbog vlastite težine. Drugi slučaj predstavlja kruta okvirna konstrukcija s dvije betonske jezgre te je primjer fazne gradnje. Pretpostavka u ovom slučaju je da će moment savijanja u pločama rasti s većom visinom te da će se pritom u temeljnoj ploči javiti velika vlačna sila odnosno naprezanja.
