Considering the complexity of the problem of stress – strain state and stability of structural systems, nonlinear theory is applied in this paper. The subject of the paper is to perform the stiffness matrix and geometric stiffness matrix, and to define the problem of bifurcation stability. Solving the problem of bifurcation stability presents...

This paper presents a monopitch timber truss roof, through the stages of its design, static calculation and execution. It is a structure that originally was not carried out in accordance with project documentation, and the realization of its restructuring failed to make the final form. It all lead to constructing a new roof structure. The intention...

In the last few years there has been a significant progress in the adoption of technical regulations regarding recycled aggregate, which affects the facilitation and stimulation of its practical application. However, the new European regulations are still incomplete, and beside that, it is evident there is no harmonization between national standard...

A non‐linear elastic‐plastic Generalised Beam Theory (GBT) is formulated and used to investigate the buckling behaviour of aluminium and stainless steel thin‐walled members. The analysis consists of calculation cross‐section (local) and member (global) deformations and has been shown to be a very efficient tool for analyzing local and global stabil...

Metrological Laboratory of Civil Engineering, Institute of Geodesy and Geoinformatics, began work in 1985, and it is performed calibration of all types of instruments used in surveying. For the whole time of his work in the laboratory were tested and calibrated a lot of different measurands that are used in geodesy. In the aim to advance the work i...

This paper treats the principle of static testing on braced girder of a sport hall built by the primary school "Srbija" in Pale. During testing simulated snow load was performed on the roof and was applied on a major steel braced (three‐band) roof grider, with span L = 23 m. The following measurements and observations were performed: measurement of...

The paper examines different heuristic an operational models in urban and regional planning, in planning of complex infrastructral projects but also in broader context of social sciences and administrative disciplines. Speciffically, it examines relations between positivist approach to heuristic, and approaches which are generally reffered to as ph...
