Design of class 4 cross section in axial compression according to EUROCODE 3
(MASE 13. International symposium 2009, 14th – 17th October 2009. Ohrid, Macedonia, Skopje 2009, Knjiga 1, 2009)
In this paper theoretic basis of design of class 4 cross section in axial compression according to EN1993-1-5 is given. Design procedure is given as an flow chart and ilustrated with an worked example. Plate buckling is ...
Compiled free surface mathematical models uncertainty propagation / Propagacija neodređenosti kod linijskih modela otvorenih tokova
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and ...
Hydraulic model study of turbulent flow measurement in sewer pipes conjunction / Hidraulička modelska ispitivanja merenja protoka na spoju kolektora sa silovitim tečenjem
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper presents capabilities and benefits of use of physical models for flow analysis in large sewer pipes and conjoining objects. A group of objects pertaining to the Belgrade Sewer System is modeled and results are ...
Warm-mix asphalt technologies in Europe and USA / Tehnologije asfaltnih mešavina po toplom postupku u Evropi i SAD
(Srpsko društvo za puteve VIA-VITA, Beograd, 2009)
Warm-mix asphalt (WMA) represents the group of technologies that enables reduction of temperatures at which the asphalt mixture is produced and placed. WMA is produced at 20 to 55°C lower temperatures than those typical ...
Vibration serviceability of building floors / Stanje upotrebljivosti međuspratnih konstrukcija s obzirom na vibracije
(Savez građevinskih inženjera Srbije, Beograd, 2009)
Satisfaction vibration serviceability of floor structures becomes more important in the case of light-weight and flexible structures. Practically, all modern floor structures are potentially problematic in the sense of ...
Testing the stability of gps oscillators within Serbian permanent gps stations network
(19th IMEKO World Congress 2009, 2009)
Periodic tests of quartz oscillators incorporated in GPS receivers in Serbia are performed in accredited metrological laboratories by the procedure adopted in metrological laboratory ML160. However, receivers of Serbian ...
Temperature field in roller compacted concrete dams / Temperaturnu polje u gravitacionim branama od valjanog betona
(Savez građevinskih inženjera Srbije, Beograd, 2009)
This paper presents 2D and 3D numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled with actual dam shape, RCC technology and adequate description of ...
Estimating double side-channel spillway capacity / Procena propusne moći dvostrukog bočnog preliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The capacity of the double side-channel spillway, consisting of the two spillways, with channels joining into a common single branch, is estimated in this paper. For the specific site conditions, such an arrangement may ...
Consequences of non planned urban development during turbulent times in Serbia - case study of suburb Kumodraz watershed in Belgrade
(Risk Management of Water Supply and Sanitation Systems, 2009)
Development is usually based oil numerous analyses accounting for planning, economy and population assessments as well as urbanism, architectural and civil engineering infrastructure planning and project design. The modern ...
Evolution of the wave function of an atom hit by a photon in a three-grating interferometer
(Physica Scripta, 2009)
In 1995, Chapman et al (1995 Phys. Rev. Lett. 75 2783) showed experimentally that the interference contrast in a three-grating atom interferometer does not vanish in the presence of scattering events with photons, as ...
