Investigation of Expansion Characteristics and Analysis-Oriented Stress–Strain Constitutive Model of Steel-Tube-Confined Recycled Aggregate Concrete
The use of recycled aggregate concrete (RAC) enables the valorization of construction waste and supports carbon-reduction strategies. However, long-term service-induced deterioration means that recycled aggregates and their interfacial transition zones inevitably contain defects, which severely restrict the safe applic...
