Concave Pyramids of Second Sort -The Occurrence, Types, Variations
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
Correspondingly to the method of generating the Concave Cupolae of second sort, the Concave Pyramids of second sort have the similar logic of origination, and their counterpart in regular faced convex pyramids (tetrahedron, ...
Geometrical Characteristics and Solid Modeling of the Grasshopper Escapement Mechanism
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
This paper presents the geometrical properties of one special type of escapement mechanism – the grasshopper escapement, by which the first marine chronometers were equipped. The most important and distinguish mechanical ...

Nonlinear stability analysis of the frame structures
(South Eastern European Graduate School For Master and PhD Formation in Engineering, 2014)
In this doctoral thesis, the nonlinear stability analysis of frame structures is presented. Numerical analysis was performed by the finite element method. Stiffness matrices were derived using the trigonometric shape ...
The Structural Transformation of Concave Cupolae of Fourth Sort Using Different Variants of Constructive Procedure, 4th International Scientific Conference on Geometry and Graphics
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
Concave Cupolae of fourth sort (CC IV) are polyhedra which lateral surface is created by folding a quadruple strip of equilateral triangles, while the bases are regular polygons. The unit cell that forms the deltahedral ...
Influence of soil-structure interaction on the seismic response of RC buildings
(Društvo građevinskih konstruktera Srbije, Beograd, 2014)
In this paper the effects of the soil-structure interaction (SSI) on dynamic response of reinforced-concrete (RC) buildings of different heights are analyzed. Two 3D numerical models of 5 and 10-storey reinforced-concrete ...
Pit protection for deep excavations-modern methods of construction and design
(Faculty of Civil Engineering Ljubljana, 2014)
In urban areas, increasingly there is a need for building of a higher number of underground floors. Construction of pit protection for deep excavations in urban conditions, next to existing objects in the complicated ...
