Shear strength Evaluation of Hybrid Coupling Walls using Finite Element Analysis (FEA)

Compressive stress at embedded region of steel coupling beam which is the main design parameter of HCW, is sensitive to the magnitude and locate of axial load because overturning moment is the main design load for this type of structure. The hybrid coupled shear wall joint were studied to identify the strength, stiffness and hysteretic characteristics etc. This analytic study was performed using FEA (Finite Element Analysis). For the verification of FE model, previously tested specimens were compared with analysis results. Total of variables were studied with FEA. From the analytical study higher axial load tends to increase the strength of hew connection but decrease the ductility comparing the results of this study to present guideline, evaluation of ductility and strength according to the axial load variation was carried out Suitable vertical reinforcement ratio and axial stress ratio for optimized connection design was suggested.
