Of special value are the results of measurements of the same values obtained along an extended service life. They provide an opportunity to compare results, track down tendencies, and more quickly recognise signs of aggravating technical condition of structures.}, abstract={The paper presents an analysis of changes to the geometry of a bridge structure - a cable-stayed footbridge used for pedestrian and bicycle traffic across the Brda river in Bydgoszcz. Measurements were made by means of surveying techniques within a period of 25 years of the structure service life.}, abstract={The collected data enabled numerous comparative analyses to be conducted. Displacements of footbridge structural elements observed across time led to formulation of recommendations for further use of the footbridge. For instance, recommendations for footbridge adjustment, including improvement of its geometry, were provided. In addition, a general analysis of the effect of footbridge displacements on its static operation was conducted.}, type={artykuł}, title={Analysis of changes to steel footbridge geometry within 25 years in sernice = Analiza zmian geometrii stalowej kładki dla pieszych w okresie 25 lat eksploatacji}, keywords={footbridges, steel footbridge, technical condition of structures, geometry of structures, kładki dla pieszych, klatka stalowa, stan techniczny konstrukcji, geometria konstrukcji}, }
