Structural Performance and Seismic Damage Modeling of Aluminum Alloy Tube–Concrete Composite Columns
This study investigates the axial and seismic performance of aluminum alloy tube–concrete long columns through validated finite element analysis and cyclic loading simulations, revealing distinct failure mechanisms for different cross-sections and proposing a machine-learning-enhanced damage model that outperforms the conventional Park–Ang approach for accurate seismic assessment.
