Two approaches for beam-to-beam contact modeling are considered in the paper. The first is the classic continuum approach with point-to-point contact discretization. The other is the coarsegrained approach where the physical intermolecular fields are applied for the modeling of interaction of continuous bodies. To describe the contact, the repulsiv...

The detection of erosion was carried out on a characteristic rocky pillar, with the localization and quantification of differences between two surfaces. For this purpose, based on the defined area and spatial configuration of the scanning object, scanner positions, arrangement of control points, and appropriate spatial scanning resolution were plan...

Trebinje is a city with a rich cultural and historical heritage associated with influential historical figures who have played a role in its physical construction and contributed to its identity. Legends about these people are a part of the city’s rich intangible cultural heritage and they can provide a solid basis for city branding. This pa...

The transition from ellipsoidal geodetic coordinates to rectangular 3D coordinates is quite simple, while the reverse procedure is somehow more complex due to the mathematical relationship between the ellipsoidal width and 3D coordinates. Until now, several methods for solving this problem have been defined and described in geodetic literature. In ...

Dynamic analysis of a spatially curved Bernoulli-Euler beam subjected to the moving load is considered in this paper. The isogeometric approach is used for the spatial discretization of the weak form of the equation of motion. Both the reference geometry and the solution space are represented using the same NURBS basis functions that guarantee an a...

Soil moisture is one of crucial parameters in modeling and analysis of groundwater flow. Measurement of soil water dynamics improves the understanding of processes and is vital for good groundwater flow model calibration. Determining soil moisture change during time by laboratory methods, as an integral part of practical classes, requires significa...

The construction principles underlying Bosnia and Herzegovina’s traditional building and the characteristics of its modernist architecture provide a basis for a set of criteria to evaluate its modernist heritage. The architect and town planner Juraj Neidhardt created a modernist-vernacular glossary of Bosnian-Herzegovinian architecture and to...

Urban development has always been related to the proximity of watercourses and the possibility of their use. Water in urban areas is essential for various infrastructure systems. Water areas in cities are also crucial for the population because they enable multiple activities. On the city shores along rivers or lakes, different spatial concepts are...

In this paper the experimental procedure for the determination of ventilation heat losses across building envelopes has been shown. The alternative name for this method is Blower Door Test or Fan Pressurization method. This text is a user manual for the determination of ventilation heat losses and parameters which is used to describe the air permea...

The replacement of natural aggregates (NA) with alternative aggregates in concrete can contribute to the sustainable development of the construction industry. This paper aims to present research investigating the effects of recycled concrete aggregate (RCA) and crumb rubber (CR) utilization on the performance of Self-Compacting Concrete (SCC) mixtu...
