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

摘要

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