This paper discusses the problem of theoretical and experimental determination of dynamic factors of road bridges. Various parameters influencing the dynamic behavior of bridges are briefly described and a review of regulations in this field is given. Also, an example of the numerical determination of the dynamic amplification factor on a specific ...

The paper analyzes gender differences in the length of study and average grade between the number of enrolled and graduated students at the Faculty of Architecture, Civil Engineering and Geodesy in Banjaluka, during the period from 1996 to 2015. It was concluded that women, in civil engineering studies, are just as successful as men. However, it is...

We propose a research of geoids as real hypersufaces. Moreover, we give adjustment of some classical results on hyperusrfaces to CR submanifolds. Our main focus is to study the properties of second fundamental form which give us information on the shape of a hypersurface. Keywords: geoids, hypersurfaces, shape operator, CR submanifolds....

It is assumed that the porous material is based on the principle of conservation of mass and the principle of conservation of energy. The validity of both principles relies on experimental observations. Experimental results of different metals were used to compare the Poisson ratio as a function of porosity. A comparison is made between the theory ...

With the adoption of Eurocodes in the field of civil engineering in Bosnia and Herzegovina, analysis of structures becomes more complex compared to previous regulations. Consequently, the analysis of crane track girders becomes more detailed, with a higher degree of analysis controls during dimensioning. This paper presents the load analysis and de...

In the subject area, the term nZEB standard appears in 2011 in the legislative framework, but it never came to life, nor in the construction of new buildings, and completely unknown in the renovation of buildings. The reasons for this are insufficiently researched possibilities, i.e., unanalysed energy savings and economic profitability during the ...

In this paper the experimental procedure for the determination of ventilation heat losses across building envelopes has been shown. The alternative name for this method is Blower Door Test or Fan Pressurization method. This text is a user manual for the determination of ventilation heat losses and parameters which is used to describe the air permea...

Control of compaction of natural soil (in excavation) or compacted in the embankment during the construction of roads is one of the basic forms of quality control of the substructure. When building high-speed roads (highways and high-speed railways), the priority is to achieve a high level of control over the performed work. In order to prevent dif...

Flood forecasting (FF) is one of the most challenging problems in Hydraulic Engineering. It is also most important due to tremendous contribution in reducing economic and life losses that usually occurs during flooding. Major part of the FF system is hydrologic and hydraulic model that simulate runoff and corresponding water levels in rivers, based...
