A DESIGN MODEL FOR CROSS-LAMINATED TIMBER SHEAR WALLS WITH SINGLE CUT-OUT DOOR OPENINGS

This paper presents an analytical model for the design and verification of monolithic cross-laminated timber (CLT) shear walls with single cut-out door openings. The model accounts for both one and two centers of rotation kinematic behaviours, enabling the prediction of lateral stiffness, internal forces, and elastic load capacity. Formulations are provided for estimating displacements and stress distributions in the lintel and uplift displacement and forces in the hold-downs. Validation against experimental data demonstrates the model's accuracy in predicting elastic response and its conservative estimation of load-carrying capacity. The proposed approach offers a practical tool for engineers, particularly in seismic applications where accurate stiffness and failure prediction are essential.
