Fig. 4. Von Mises stress distributions in OSB-sheathed CFS wall panels with different screw spacing at failure. (a) Model 75; (b) Model 100; (c) Model 150. 4. Conclusions In conclusion, the numerical investigation conducted using the FEM in Abaqus CAE (2024) effectively demonstrated the significant influence of screw spacing on the mechanical behavior of double-sided OSB-sheathed LSF shear walls. The study confirmed that the panel with the smallest screw spacing of 75 mm achieved the best overall performance, presenting the highest maximum load capacity, the lowest displacement, and the greatest elastic
