The strut-type hybrid system can be made in different geometric shapes, which are affected by: the number and arrangement of struts, the shape and position of the cable in relation to the girder, and the size and shape of the cross-section of the girder. When choosing a system, all the listed parameters can vary geometrically, which has consequences on the behaviour of the girder when carrying the load by directly affecting the change in the stiffness of the system. In addition to the geometric parameters, the stiffness of the hybrid system is affected by variations in the properties of the incorporated materials and their mutual relations. In this paper, based on a detailed parametric analysis, the principles of design, the choice of materialisation, and the possibility of further optimisation of the persistent-type hybrid systems are given, with the aim of additionally increasing the load capacity and reducing the deformability. The results of this research are presented in the form of general expressions and diagrams, which can be applied with sufficient accuracy in practice when choosing the form and materialisation of the hybrid system, as well as the possibility of further optimisation of the system by applying pre-stressing. Using the example of external pre-stressing of a glued laminated timber girder, with the assumption of ensuring the lateral stability of the system, the results of the analysis of the behaviour of such a system under load in real conditions, i.e. the influence of the environment and changes in material properties, are given.

Modern-day is defined as a period of globalization, a complex construct that can pose a threat to maintaining the uniqueness of a place and creating a distinctive city identity. The hypothesis of this paper is that, while the phenomenon of globalization is researched within different disciplines, a common interdisciplinary theme stands out - the experience and perception of urban space that further builds a unique impression of the observed scene. The assumption will be investigated through the formation of a qualitative model for examining the urban potential with the aim of affirming the visual quality of the place as an important factor in the construction of local identity. The established model is examined through case studies of the 20th-century heritage. This period was chosen because it represents the subject of a contemporary global discussion about the conservation, activation and use of heritage in urban structures. The premise is that the qualitative model can be adequately applied to architecture from this period and contribute to its visibility and understanding, as well as to the examination of its role in the creation of contemporary local identity. The research is significant because it enables an interdisciplinary consideration of heritage as a key factor in building the modern city identity based on its visual impression.

There are more than forty projects for building Orthodox churches preserved in the Archives of Bosnia and Herzegovina in Sarajevo. Presented here are four projects for the churches with domes and one for three-conchal building with no dome.
The oldest projects are those of Višegrad (dated from 1882) and Zenica (dated from 1889), which represents the church built between 1883-1885. Name of the architect remains unknown in both cases– a project for the church in Višegrad is not signed and signatures of Franz Blazek and perhaps Miloš Komadina on a project for the church in Zenica are not a proof of them being the authors. Projects testify the wishes of the church patrons for their temples to show connection with the Serbian sacral architecture of the 13th century (Višegrad) or to visually manifest growing economic power and social standing of the Serbian Orthodox community, building their church similar to the cathedral in Sarajevo (Zenica). Project for the St Sava church in Blažuj was created in 1895/96, following wishes of the patrons, representatives of the Church community. Project of August Butschа embodied the idea of national recognition in historicist neo-byzantine style created by famous architect of historicism Teophil Hansen, which was back in the time generally recognized as a neo-Byzantine style, and in this specific case as an Orthodox and Serbian one. “Serbian-Byzantine style” of the mausoleum chapel of Lower Tuzla merchants Jovanovićs at Trnovac was almost for sure initiated by their wishes, and the chapel was built in 1889 by well-thought design of the architect Franz Blazek. Neo-Moravska three-conchal basis of Vodjenica church, projected in 1911 by Milos Miladinovic, can be considered as an aspiration of the church patrons to have their temple look like Mostanica.
Projects presented can be considered as rare testimonies to the role that “carriers of the patronage mechanism in the process of originating and forming of the church architecture” had in Bosnia and Herzegovina in the Austro-Hungarian period, when the lack of national state resulted in lack of a clear view of the sacral construction forms that would express its identity.
