Activity concentrations of 226Ra, 232Th and 40K in some building materials used in Montenegro were measured by the gamma spectrometry (HPGe spectrometer and multidetector spectrometer PRIPYAT-2M), and the results are presented in this paper. Levels of the radionuclides in analyzed sand, cement, brick, gypsum, ceramic tile, as well as marble and gra...

This paper provides an overview of the authors’ research on the free vibration analysis of circular cylindrical shells using the Dynamic stiffness method. Exact frequency-dependent dynamic stiffness matrices, derived from Flügge shell theory and its shear-deformable extension, enable highly accurate prediction of modal properties without...

Virtual tours of monuments become more and more a vital part of the promotion of the culture and therefore tend to be one of the main areas of study in the field of cultural heritage. These representations offer users the chance to tour in areas located far away. In order to create accurate and correct 3D representations of the monument, geometric ...

This study emphasizes numerical modeling of soil medium including boundary conditions, rather than the conventional focus on input earthquake accelerations with simplified Winkler soil models typically used in soil-structure interaction (SSI) problems. A six-story frame structure founded on relatively soft ground is numerically simulated in ANSYS u...

This paper demonstrates the use of terrestrial laser scanning (TLS) to detect deflection in lattice steel girders inside a hall structure. Data were acquired using the Trimble TX8, producing a point cloud of over 349 million points. After registration and classification, the processed point cloud served as the basis for deflection analysis. Girder ...

The Devil’s Town site is a unique geomorphological formation in southern Serbia, comprising over 200 earth structures. This site has been monitored using non-invasive techniques and a high-resolution point cloud was generated through photogrammetric imaging with an Unmanned Aerial Vehicle (UAV). In this study, automatic detection of the earth...

Architectural education has often advanced at a slower pace than the rapid transformations of spatial practice and society. Within this imbalance, the architectural workshop emerges as a condensed yet intensive format of experimentation, providing a distinctive environment for testing pedagogical approaches. This study critically examines the works...

Decarbonizing the existing building stock requires moving beyond an approach based solely on reducing operational energy consumption and toward an integrated life-cycle assessment perspective. The standardization framework for building renovation encompasses energy performance, life-cycle assessment (LCA), environmental product declarations (EPDs),...

Abrasion resistance is a critical durability parameter of foamed concrete applied in floor screeds and wear - exposed surface layers. Owing to its cellular structure, abrasion performance depends on bubble morphology, including size, distribution and uniformity. This paper presents an experimental study combining high - magnification microscopy wit...

The paper describes the phases of bridge construction, geodetic measurements and monitoring procedures during the characteristic phases of construction. In the experimental part of the work, the procedure of geodetic observation of the bridge construction based on the analysis of two measurement epochs is shown. Open-source software Java Applied Ge...
