Tensegrity type cable domes are three-dimensional structural configurations, prestressed inside the perimeter compression ring, in which the continuous tension throughout the roof structure is made by continuous tension cables and discontinuous compression struts. These kinds of structures can be formed like spatially triangulated networks or like networks nontriangulated in space. This paper examines some effects of network geometry on the behaviour and structural efficiency of tensegrity type cable domes. In this paper the roof cover is considered non-interactive with the supporting structure, unlike rigidly clad tensegrity type cable domes. Since the main bearing elements of tensegrity type cable domes are prestressed cables, they show non-linear load deformation and rely upon geometric stiffness. A geometrically non-linear analysis of non-triangulated and triangulated structures for different load conditions was conducted employing a computer program based on the perturbation theory. The incrementally-iterative procedure, with an approximation of the stiffness matrix by combining the elastic and geometric stiffness matrix, allows detection of structural instabilities

Sustainable building involves reducing negative environmental impacts with a simultaneous increase in life quality. The aim is to optimize building performances while considering all aspects of sustainability: environmental, economic, and social. The building structure determines the building’s performances, and it should be designed and evaluated as a subsystem of the building, in line with the objectives of the system–building. This paper investigates structural design based on integrated design objectives within the criterion of social benefits for users throughout the use phase of the building, focusing on protection and safety, aspects of comfort, spatial organization, spatial adaptability, and maintenance. The problem was studied using integrative literature review methodology and system theory. The main findings of the research are a review and critical analysis of the representative literature and the derived conceptual framework for structural design based on the criterion of social benefits for building users, which should support more comprehensive and more efficient decision-making during systemic design and optimization of buildings. The presented integrated literature review indicates the need for the application of a systemic approach to structural design in order to create sustainable buildings.

The advances and proliferation of digital technologies impact architectural practice asking for a revision of not only design production but also the education of future professionals. Using a case study from the University of Belgrade—Faculty of Architecture, this paper examines the efficient application of 3D printing as a design tool and opportunities for the implementation of this technology in architectural education. The research goal was to establish an educational framework for the studio course that was appropriate to local settings, starting with a review of educational approaches and usage of 3D printing in architectural design. Starting with the premise that there is a bidirectional relationship between design and its tool, educational framework for architectural design studio was proposed, tested in real educational settings, and evaluated. The results indicate that the use of 3D printing in studio course proved to be an effective tool for design exploration and presentation that supports (1) linking the logical way of thinking that requires parametric modeling with concept-based thinking; (2) change in mindset that occurs in the design process when students have a physical model in front of them to assess; and (3) improvement of deep understanding of spatial cognition among students as well as their competencies related to the use of the specific technology in the design process. The paper demonstrates how 3D printing technology improved educational methods, impacted students’ experiences in the design process, and elevated design exploration to previously unattainable levels of materiality, detail, complexity, accuracy, and aesthetics.

Original scientific paper This paper demonstrates the results of experimental determination of load bearing capacity of structural timber member connections realized by WOLF and LKVC metal connector plates. Considering the complexity of the connections realized by these modern mechanical fasteners, this paper deals only with plate anchorage capacity (stress in the metal-wood contact). The aim of the conducted experimental study was to determine the metal connector plate anchorage capacity in accordance with the provisions of Eurocode 5 and also to analyse the ratio of the load bearing capacities of these two types of connectors in terms of their geometry. Experimental testing was conducted by loading of multiple samples up to the limit plate anchorage capacity. Discussion of the test results included the analysis of the connection deformation for different levels of load, as well as the mode of reaching the limit plate anchorage capacity. Review of the determined limit plate anchorage capacities, for the determined displacements of connection, was given in the conclusion, together with the comment on test results.

S obzirom na kompleksnost veza ostvarenih ovim savremenim mehaničkim spojnim sredstvima, predmet rada obuhvaća samo nosivost bočne veze (naprezanje u spoju metal-drvo). Cilj provedenih eksperimentalnih ispitivanja je bio da se utvrdi nosivost bočne veze ostvarene metalnim konektorima, u skladu s odredbama Eurokoda 5 i da se paralelno s tim analizira odnos nosivosti ova dva tipa konektora, s aspekta njihove geometrije. Eksperimentalno ispitivanje je provedeno na više uzoraka, opterećivanjem uzoraka do dostizanja granične nosivosti bočne veze. Diskusija rezultata ispitivanja je obuhvatila analizu pomjerljivosti veza za različite nivoe opterećenja, kao i način dostizanja granične nosivosti bočne veze. U zaključku je dan komentar o utvrđenim graničnim nosivostima bočne veze, za određena pomjeranja veze, i zauzet je stav po pitanju dobivenih rezultata.
