This investigation demonstrates that connection specifications affect shear wall performance, indicating a need for improved design methods.
We investigated the influence of varying connection specifications on the performance of shear walls with identical properties, focusing on the condition of preventing premature failure at column bases and heads. Our experiments revealed that connection performance affects the shear wall’s performance. This suggests that the ultimate state of timber wall structures is not adequately controlled in the allowable stress design method. We therefore proposed a formula to estimate the actual shear wall’s performance using the rigidity of the connections and the true shear performance, and its validity was confirmed by comparison with experimental results.
