Shear Strength of Double-Skin Truss-Reinforced Composite Shear Walls: Finite Element Analysis

Year: 2025

Type: article

Abstract: This study investigates the shear behavior of double-skin truss-reinforced composite shear walls through finite element analysis validated by published tests. Parametric studies reveal that the shear strength increases with the axial compression ratio up to a threshold of 0.6, beyond which it declines. However, increasing the aspect ratio significantly decreases the shear strength when the aspect ratio does not exceed 2.5. Additionally, increasing the spacing–thickness ratio reduces the shear strength, with a recommended limit of 60. Truss connector specifications are found to have a minor impact on the shear resistance. A new design formula for predicting the ultimate shear strength is established based on finite element analysis (FEA), which yields relatively conservative predictions with acceptable accuracy.
