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...

This study presents a comparative analysis of proprietary and custom point cloud classification pipelines in the context of cultural heritage documentation, using the Monodri Bridge in Evia, Greece, as a case study. The research evaluates the performance, flexibility, and suitability of commercial software solutions versus tailored, open-source wor...

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 ...

Proračunske analize i procjena uticaja zidane ispune na seizmički odgovor višespratnih armiranobetonskih okvirnih zgrada u domaćoj inženjerskoj praksi najčešće nisu sastavni dio projekta konstrukcije, iako se pri izvođenju okviri uobičajeno ispunjavaju zidanjem zidova na tradicionalan način, bez posebnih mjera izolacije. Kroz uporednu...

Composite steel and concrete structures are widely used in modern civil engineering due to their structural efficiency and economic performance. However, conventional composite systems limit the possibility of full structural disassembly and reuse of steel structure elements and composite slabs, which is increasingly important in sustainable constr...

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...

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...
