Using high-strength material for precast concrete columns provides smaller column dimensions at lower stories of high-rise buildings than precast concrete columns with normal-strength material. Between the precast elements, connections play an essential role since they should provide overall structural stability. Precast concrete columns with Grouted sleeve (GS) 's mechanical connection perform similarly to monolith-reinforced concrete columns. However, it affects local and global member behavior. It is important to understand the deformation response and to predict the behavior of high-strength precast column that employs GS connection. For that purpose, it requires suitable and effective tools. Finite-element analysis (FEA) effectively reduced production costs to predict the full responses of the precast concrete column using GS connection. This study presents a numerical analysis of a double-curvature column that employ GS connection called GH10. The specimen was made from a high-strength concrete of 74 MPa and high-strength steel rebar of SD685 and SD785 for longitudinal and transversal reinforcement, respectively. The numerical analysis was executed using finite element software, 3DNLFEA. The model was investigated using increment monotonic and constant axial compression loading. The validation was performed on the load-displacement behavior and curvature diagram along the column height. The results show that the model behavior prediction corresponds well with the experimental results. Information about the stress of longitudinal and transverse reinforcement and crack pattern prediction are discussed. [ABSTRACT FROM AUTHOR] |
