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...

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...

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...

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...

This paper examines the process of modeling, peculiar for architectural creativity, focusing on the perception of models by creator on the one hand, and the perception of the observer (user) on the other. The research is conducted on two levels: theoretical and practical. Practical work includes modeling according to given topics that implies proce...

This paper raises the issue and examines the causes and effects of the neglect of abandoned and underused spaces in the Republic of Srpska (brownfield spaces, greenfield spaces), emphasising the necessity for their regeneration. Urban regeneration is manifoldly understood as a process, strategy and comprehensive method of urban renewal  ‐ &nbs...

This research addresses the issue of transformation of urban landscape, especially its green structure, in the context of urbanisation understood as a complex socio‐spatial process possessing both global and local characteristics. This new urban landscape extends beyond the traditional relations between the city center and periphery as two distinct...

An approach to elasto‐plastic analysis of engineering structures is presented in this study. Simple plane truss finite element with two nodes is used. This element is ideally suited as a basis for studying plasticity theory since it implies one‐dimensional state of stress and strain. Material model of linear isotropic hardening is applied. Algorith...

This paper will address methodological model of architectural design using the type and typological transformation as a mechanism for preservation of identity and cultural specificity in the growing phenomenon of globalization and unification of space. Theoretical framework of generative typology shall be presented, which will be the base of design...

Deformation measurements are of great significance and importance based on which in the processing and analysis of measurement data determined displacements and deformations of construction objects during the exploitation and obtained information on whether the construction objects comply with expectancy. The consequences of neglecting the need for...
