Preliminary design of wooden road bridge

Abstract

This paper aims to review different constructed wooden bridges hence give a basis for further development. The second purpose of the research is to develop the preliminary timber bridge design for the Pomarkku Bridge. The information was gathered mostly from literature and the Internet. Also some field researches in Pomarkku were carried out. After the analysis of the existing timber bridges composite SLT and truss options for an old stone bridge replacement was offered. BIM models of variants were done and their fitting to environment assessed by photo montage. The approximate cost estimation was conducted. Difficulties and tips of timber usage in load bearing bridge structures were discussed in this thesis. Achievements of wooden bridge industry were displayed. The possibility to use timber structures in the case study bridge was showed and assessed.
