Pseudodynamic Tests and Earthquake Response Analysis on Scaled Three-dimensional Models of Conventional Wooden Structures

Abstract

We conducted pseudo-dynamic tests and earthquake response analysis on half scaled three-dimensional models of conventional wooden structures, by changing horizontal diaphragms stiffness, vertical walls stiffness and ground acceleration ratio in the perpendicular direction on the specimens. Displacement response of simulation agreed well with pseudo-dynamic tests. The lumped mass 3D-model is suitable for predicting earthquake response of this structure. We conducted also additional simulation on the specimens. The maximum displacement in the parallel direction of specimens was more affected by the eccentricity in the perpendicular direction than by floor stiffness. When the eccentricity ratio is under 0.3 in both directions of specimens, the ground acceleration ratios in the perpendicular direction and floor stiffness little effect on the maximum displacement response parallel to the specimens.
