PERFORMANCES OF WOODEN LADDER-TYPE FRAMES FOR SEISMIC REINFORCEMET OF TRADITIONAL TIMBER STUCTURES
There are many traditional timber structures, such as temples, shrines and town houses in Japan. Their rational seismic evaluation is the most important in order to mitigate probable damages caused by great earthquakes in the near future. Thus, the establishing the evaluation method and seismic reinforcement are urgently needed. We, therefore, propose wooden ladder-type frames for seismic reinforcement of traditional timber structures. In order to evaluate the proposed frame, we established the formulation of seismic performances using Pasternak model. We applied the Pasternak model to the elasto-plastic embedment behavior of wood joints, considering the orthotropic properties and the strain hardening. In order to confirm their performances, full scale experiments were carried out and the results are discussed.
