Research on Wind Structure in the Wind Tunnel of Wind Engineering Laboratory of Cracow University of Technology

The paper is devoted to the research of the wind structure in a wind tunnel. The work consists of the measurements of flow velocities with use of the X hot-wire anemometers at different sets of turbulizers, as well as the statistical analysis of the measured signals. Power spectral density functions have been obtained for 45 sets of turbulizers placed at the inflow, then 6 sets related to PSD functions representing real wind characteristics have been selected for further analysis.

Influence of exploitation damage on the capacity of scaffolding frame standards

The following paper presents numerical analyses and laboratory tests used for analyzing the impact of exploitation damage to the main structural members of the scaffolding frame system. The presence of inevitable defects reduces the strength of material compared to the theoretical strength. Numerical analysis preceded by own laboratory research allows you to describe precisely the behavior of the element. Performing a series of calculations gives information on the impact of the damage size and location on the bearing capacity of the scaffolding frame.
