RESPONSE ANALYSIS METHOD OF TRADITIONAL WOODEN STRUCTURE PLACED FREE ON FOUNDATION
In this paper, a method of response analysis for traditional wooden structures is presented. Their columns are just placed and not fastened on foundations. Sliding and rotating behaviors in addition to shear deformation of wooden frame occur during earthquakes, and they are then considered in the analysis. The effects of impact between columns and foundations are also taken into account. Necessary conditions for occurrences of sliding and rotating are examined, and two-dimensional equations of motion are formulated. In order to verify the proposed method, shaking table tests were carried out. First, the analytical results for sliding response of a short and rigid wooden frame model without shear deforming and rotating under horizontal excitation show good agreement with the results of shaking table tests. Secondly the analytical results for shear deforming, rotating and sliding responses of a full-scale wooden frame agree well with the experimental results. It is found that the proposed analytical method can comprehend the special behaviors including sliding and rotating of traditional wooden structures under earthquakes.
