PREDICTION OF STRUCTURAL PERFORMANCE OF SUGI PLYWOOD SHEAR WALL BY COMPUTER SIMULATION BASED ON HOFFMAN FAILURE CRITERION

摘要

The primary objective of this study is to clarify the optimum arrangement of plywood-to-frame connectors for enhancing the structural performance of a built-in plywood shear wall system by computer simulation. The investigation was conducted based on a finite element model of the shear wall with built-in plywood to simulate its mechanical behaviour when arranging eight connectors differently. Based on the maximum value of Hoffman failure index obtained from the analytical results, the position of eight connectors only along two horizontal frame members was convinced to be more effective in upgrading shear wall performance than that only along the vertical frame members. The optimum arrangement of connectors has been figured out to disperse them along the surrounding frame, thus both stiffness and strength of the shear wall with built-in plywood reached the highest among four arrangements.
