Long-term deformation measurements of large span timber structures

The paper includes conclusions from evaluation of results obtained from long-term measuring of innovative types of timber structures. Based on the results of measurements of vertical and horizontal deformation components it is possible to analyze the real behaviour of structures in given conditions. By assessing deformations in various stages, including particularly external and internal environment temperatures, relative air humindity and moisture content of wood, decisive parameters for real structure behaviour can be established. Data are processed from period 2001-2008.
