EVALUATING IN-PLANE SHEAR MODULUS OF WOOD- BASED STRUCTURAL PANELS BY RACKING TEST OF SMALL NAILED WALL

摘要

Racking test of small wall specimens sheathed with various wood-based structural panels was conducted and the in-plane shear modulus of the panels was evaluated by several measurement methods. The validity of the obtained shear modulus and the efficiency of the measurement methods were discussed. As a result, in the area of lower lateral forces, the shear modulus calculated by diagonal displacement did not show a steady value. While the shear modulus calculated by absolute coordinate was comparatively well corresponding to the values calculated by diagonal strain. The measurement method by the absolute coordinate can be used as an effective method for calculating the shear modulus of wood-based structural panels.
