Abstract

The paper presents results of exceptional experimentation, which focuses on the long-term loading of timber beams. The uniqueness of the research is given by real dimensions of samples and by the term of loading over one year. In the frame of investigation four currently often used timber girders had been investigated. The aim was to observe the time dependence of deflections over time. According to deflection curves the approximations for simulating the final deflection at the end of structure’s lifetime had been defined. The obtained creep coefficients were compared with the values listed in the valid standards.
