AB  - The paper discusses the structural behaviour of concrete-filled steel tube columns (CFT)
when applied to the top-down construction method as temporary internal supports for ceilings. Their
ultimate capacity to take into account the actual boundary conditions of the column is essential for
successful application in construction. The paper presents the full-scale in situ testing of four slender
specimens with variable D/t ratios under concentric axial loading. The CFT columns were supported
on the previously jacked concrete piles. In addition, detailed finite element numerical models in
ABAQUS and PLAXIS computer programs were developed. The models include the nonlinear
behaviour of materials and the nonlinear behaviour of soil. The soil–pile–column interaction and
impact of the CFT column–pile connection stiffness on global column stability were considered.
The numerical model was validated by comparison with the experimental results. In conclusion,
the coefficient for the effective buckling length of the studied columns is proposed. Finally, the
experimental results of the critical buckling forces were compared with widely used international
design codes Eurocode 4-EC4, American standard-ACI and the Australian standard-AS.

AB  - In the cut zone number 6 on E-80 Niš-Dimitrovgrad highway from km 28 +
478,00 to km 28 + 643,00 slope stability was affected causing mass movement. Additional
inclinometers measured the mass wasting thickness between 14 m and 25 m. The height
of the cut determined the slope protective backfilled gallery to be the best solution. The
paper presents the detailed geostatic calculation of landslide stabilization using computer
programs Plaxis 2D and RocScience Slide. Further, it shows the static calculation of the
protective gallery in the computer program Radimpex Tower 3D. Results confirmed that
the proposed structure was rigid enough to provide the necessary protection for the road
structure.

AB  - The paper presents retaining structure to stabilize the landslide in the middle
section from 878+775 to km 878+825, and slope protection on both left and right sides
in order to provide vertical cutting and excavation to the level of highway platform.
Retaining structure was designed as micro-pile wall with three different types of walls
depending on the pile position. Micro-pile is made from steel pipe dia. Ø139.6 mm and
8.8mm thick wall, which is filled with cement mortar of minimum strength 30 MPa. In a
constructive view, the designed retaining structure is a plate that is resting on the
continual tie beams, which are supported in discrete points by geotechnical anchors.
Calculation of stability and bearing capacity of protective structure was carried out in
several phases. Phases are modeled according to the technology of execution of works.
The calculation was performed in FEM program called Plaxis 2D. This calculation is
based on the finite element method, using an incremental, iterative process. Based on the
performed analysis, calculation of stability and bearing capacity, it can beconcluded
that designed support structure satisfies all the necessary conditions of stability and
bearing capacity.

AB  - In this paper, results of experimental investigation of bearing capacity and stability of slender and moderately slender CFT circular tubes are presented. The effects of ratio thickness/ radius of steel cross section and support conditions are investigated. Numerical simulation for the tested examples was performed in computer program ABAQUS. In this simulations, nonlinear constitutive models were used for modelling of concrete, steel and concrete/steel connection. With modified Rick's method critical buckling force for the CFT column was calculated. Verification of the obtained experimental results was performed with comparison with several world standards: EC4, ACI, AS, AISC, as well as with the results obtained in ABAQUS.

AB  - CFT columns are one of the basic structural elements in "top-down" construction method. Because of the large depth of excavation the question of stability of these columns raises. This paper presents a procedure for calculation of critical buckling force of CFT columns which are on the upper side elastically fixed in the concrete ceiling and on the bottom side elastically fixed in the drilled pile. Using computer programs ABAQUS 6.12 and LPILE, as well as appropriate constitutive models the boundary conditions on the upper and lower end of the CFT columns are determined. For a building called "Cvijetni prolaz" in Zagreb, using program created in Excel the critical buckling force of elastically fixed CFT columns is determined. The dependence of the critical buckling force decreasing with increasing depth of excavation is presented. The impact of concrete class, diameter and wall thickness of the steel section, length and diameter of the pile, the thickness of the ceiling on the critical buckling force of CFT columns is analysed. The results are shown in diagrams and tables.

AB  - One of the methods of construction which are  increasingly used in urban conditions is a "Top Down" method. This method of construction is suitable when constructing buildings with a larger number of underground floors. Construction of the building is done from top to bottom where the ceilings of a structure are used for shoring of the structure for pit protection. One of the important elements in this method are internal ceiling supports. In the design engineers tend to minimise the costs and dimensions of these supports. This leads to the problem of their stability and capacity. This paper presents the analysis of bearing capacity of steel pipe filled with concrete which is on the bottom end elastically wedged in a pile and on the upper end in a constructed cealing of the building.
AB  - Jedna od metoda gradnje koja se sve više primenjuje u gradskim uslovima jeste "Top Down" metoda. Ovakav način gradnje je pogodan kada se izvode objekti sa većim brojem podzemnih etaža. Konstrukcija objekta izvodi se odozgo na dole pri čemu se tavanicama objekta vrši razupiranje zaštitne konstrukcije temeljne jame. Jedan od bitnih elemenata kod ove metode jesu unutrašnji oslonci tavanica. Pri projektovanju teži se da koštanje, odnosno dimenzije ovih oslonaca budu minimalne. To dovodi do problema njihove stabilnosti i nosivosti. U radu se prikazuje analiza nosivosti stuba od čeličnih cevi ispunjenih betonom koji su sa donje strane elastično uklješteni u šip, a sa gornje strane u izvedenu konstrukciju objekta.

AB  - Zidovi ispune unutar AB skeletnih konstrukcija obično se posmatraju kao nekonstruktivni elementi i zbog toga se njihov doprinos zanemaruje pri proračunu konstrukcija. Istraživanja u novije vreme pokazala su da zidana ispuna može značajno izmeniti ponašanje konstrukcije. U ovom radu sprovedena je analiza ponašanja AB ramovske konstrukcije sa ispunom pri dejstvu zemljotresnog opterećenja. Ispuna je modelirana prema preporukama FEMA koristeći softverski paket SAP 2000. Za definisanje histerezisnog ponašanja ispune izabran je Pivot model. Rezultati proračuna upoređivani su sa rezultatima proračuna korišćenjem Kinematic modela na osnovu čega su usvojeni zaključci koji su prikazani u radu. Infill walls within frame buildings have been considered as non-structural elements and thus have been typically neglected in the construction design process. Research in recent years has shown that masonry infill can significantly alter the behavior of the structure. In the present paper an analysis has been made to study the behavior of RC frames with infill when subjected to dynamic earthquake load. Infill has been modelled according to FEMA using software package SAP 2000. Hysteresis behavior of infill was defined with Pivot model. The results of the calculations are compared with the results made using Kinematic model, based on this conclusions are presented.
