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 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...

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 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 ...

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...

This paper discusses vibration serviceability assessment of cross-laminated timber (CLT) floors induced by human activities, with special emphasis on vibrations induced by walking. In the first part current design criteria for vibration serviceability check of timber and CLT floors were analyzed in line with the more general vibration performance-b...

In the pavement structure, stresses and deformations occur due to the effect of the environment and traffic load. The stresses that will occur mostly depend on the traffic load, the type of materials used, the modulus of elasticity of the materials used, the thickness of the layers... Due to the effect of the environment and traffic on the pavement...

This paper analyzes the impact of the quality of geodetic base, i.e., the method of obtaining spatial data for the purposes of road design. Quantities of earthworks, shape and size of the road body obtained by designing the road on geodetic base obtained from different sources (LiDAR scanning, topographic maps, and Open-source data) are compared to...

The paper presents the results of our own experimental research on the effect of the high range water reducing admixture content – HRWRA (applied in the range from 0.8 to 1.2% by mass of cement – mc) on the properties of self-compacting concrete in the fresh and hardened state. The research showed that increasing the HRWRA content lead...
