Using limited materials for numerical modeling of structural samples and comparing the behavior of samples with each other in order to reduce the number of straw test samples in order to reduce laboratory costs is one of the best methods today. ANSYS is one of the finite element software that is used for modeling reinforced concrete elements by Sol...

The task was set, due to the capabilities of modern software systems, to assess the effect of the increase in inelastic deformations under prolonged load action on the loss of stability of thin-walled dome coverings. The study of the dependences of the forms of the loss of stability of dome covering from creep concrete that will help further with o...

This study presents results of chemical leaching of contaminated soil from several metallurgically loaded locality of Richnava in Slovakia, applying two chelants – Na2EDTA and Na3EDDS of different molar concentration, done at different leaching conditions. The lower molar concentration (2 mM) of chelants showed comparable effect on Mn, Ni, As...

In the present paper, the authors develop a methodology for stability monitoring of the hydrotechnical-defensive embankment that is exposed to heavy frequent traffic. The proposed methodology envisages several phases of observation, work and monitoring: (1) macroscopic observations, (2) geophysical-geoelectric tests, (3) group of exploration works,...

In many projects, piles are designed and installed as the ultimate solution in foundation construction, load transition to the resistant subsurface layers, providing lateral resistance, and overcoming the poor performance of surface soils. Pile design should be done with respect to structural consideration, the load-carrying capacity of the surface...

Efficient roadway management requires knowledge of the structural capacity of the roadway or the load-bearing capacity of the pavement structure. In order to determine the existing conditions of the pavement structure and define appropriate intervention measures, it is necessary to determine relevant impact on surface of the pavement structure on h...

The natural bentonite and bentonite/iron oxide composite were used as sorbents of Cu(II). Their sorption properties were examined under the different conditions such as pH of the solution, initial metal ion concentration. The bentonite removed 71 % Cu(II) while composite 90 %. Their maximum adsorption capacities were 34.1 and 44.4 mg Cu(II) g -1, r...

In paper is given overview on geotechnical characteristics of the terrain on location of a bridge number 3, on highway Tarcin – Konjic. Complexity of geological structure, in near surface where it consists from sediments of weathering crust to depth of around 30,0 m, as well as in substrate that consists of sediments of clayey debris, determined th...
