A new dynamic load testing of bridges is proposed and theoretically investigated. A transient analysis of passing vehicle over a bridge in ANSYS and an analytical program [...]

Ageing, erosion, local damage or increase of the operating loads can decrease the reliability and load bearing capacity of building structures. Vibration monitoring may p [...]

Summary: Assessment of degradation rate of material can be carried out by many experimental techniques differing in complexity and sophistication. A relatively simple met [...]

The paper describes an analysis for the purpose of theoretical lifetime prediction of telecommunication towers, guyed masts and antenna’s extensions. It brings simple a [...]

The damage of structural masonry walls is one of the most widespread harming injuries and cause of loss of serviceability and seismic capacity for a building. Therefore a [...]

The partial investigations of orthotropic decks carried out in the Institute of Theoretical and Applied Mechanics, v.v.i., in Prague for a project of the European Union � [...]

The paper deals with vortex-induced oscillations of footbridge hangers at a very low wind speed. The two-spans (2x50m) reinforced concrete structure with the central pylo [...]

Downtrend of the fundamental natural frequency of a structure with time, detected by periodical diagnostic in-situ measurements, can signal damage starting anywhere in th [...]

The authors have noticed the newest observations and few analysis of excitation mechanism. They suppose that the import knowledge of the forces frequencies of step or str [...]
