- Extreme wind load and its influence on the stress and deformation state of the structure (2023 - 2026, N. JENDŽELOVSKÝ, VEGA 1/0155/23)
Annotation:
The project aims to analyse the behavior of the building structure as a whole and also its individual load-bearing elements. In project reinforced concrete and steel structures will be analysed under extreme static and dynamic climatic loads, which include: wind, snow, earthquake, or fire loads. At present, we are facing extreme weather fluctuations, which amplifies the chosen solution topic. The analysis of structures will take into account modern technologies and construction procedures. Wind effects acting on individual structures as well as system of buildings will be analysed. If possible, the wind tunnel will be used. The influence of uncertainty of input quantities in individual case studies is determined by sensitivity and probabilistic analysis. The structures are calculated taking into account the interaction with the subsoil. All new structural design procedures and detection of quality are based on the idea of reducing the economic costs of the building construction.
- Smart on-line system for bridge health monitoring (2022 - 2025, M. SOKOL, VEGA 1/0230/22)
Annotation:
The main objective is to define an appropriate system for data collection and processing, numerical modeling, analysis and calibration of bridge structures in order to provide the responsible authorities with an early warning
system for bridges especially for these they are not in very good condition and therefore need constant monitoring. The necessary technical equipment needs to be designed, prepared and tuned. The strengths and weaknesses of the system should be defined and its parameters should be set by a deeper numerical analysis with regard to different damage scenarios. Numerical analyzes related to a specific traffic load should be compared with experimental data. Temperature effects should also be considered. Larger parametric case studies combined with measurements with a larger number of sensors are needed to verify and calibrate the
numerical model.

Experimental dynamics - Innovation of a laboratory
The project deals with the innovation of the laboratory (Department of Structural Mechanics, FCE STU in Bratislava). Thanks to that, the improvements of the courses Dynamika stavebných konštrukcií and Dynamics of Structures will be done. The main aim is to improve the experimental models as well as the improvements of the artificial exciter suitable for these models. Students can measure repeatedly with the device that allows them to measure and control the exciter. The study material will also be among the results of the work. That document will mainly cover instructions for the individual experiments.
