Web04. mar 2024. · The column concrete is modeled by dividing it into the confined concrete inside the lateral reinforcement, and the unconfined concrete outside. For the material model of concrete, Yassin (1994)’s model [ 24 ] was used; while for the confined concrete, Mander (1988)’s model [ 25 ] was used. Web10. feb 2024. · The concentric axial confined strength f cc is determined based on the multi axial stress state procedure followed by Mander based on the concrete plasticity model developed by Willam and Warnke with surface meridian equations for compression C and tension T derived by Elwi and Murray from the 3D concrete data of Schickert and …
