2) On the Strength of Wooden Construction under Long Sustained Load

To investigate the strength of wooden construciton under long sustained load, wooden members and joints were tested by the authors. In this paper, the results of our experiments including that of other authors are summarized in three items described below: 1. Bending creep tests of wooden beams; 2. Shearing creep tests of wooden joints, iron and wooden dowels, nail, bolt and glued joints; 3. Bending tests of wooden trussed girders. Furthermore, on the basis of the above results, the bearing stress or bearing power of the wood or Wooden connections and the methods of calculation for wooden constructions for long sustained load are suggested.
