A timber Warren truss bridge was developed by the authors in 2010 as the emergency bridge which can be assembled within a short time in disaster. It was obtained that the construction time was within half an hour with human power assembling the bridge. However, processing the end of truss member was necessary to insert the steel connection plate. Removing the distortion of welding in processing the steel connection plate was also necessary as the problem. Therefore, this study presents connecting method without special processes of timber member except for bolt holes. Also, the connection system without welding is applied in this bridge. As for the material, the market size of 2×8 timber which can be bought easily is adopted in this presented truss bridge. The results of construction tests in the gym and in the field are shown in this paper. The results of loading tests are also reported to confirm the structural performance.
