There is growing interest in the seismic application of shape memory alloys (SMAs) in concrete structures. However, for the seismic performance of such new class of materials with complex thermomechanical behavior to be fully understood, more advanced simulation tools are required. This study focuses on investigating the application of thermally prestressed SMA spirals as a retrofitting measure for RC columns with insufficient flexural ductility. The study adopts a novel simulation framework which incorporates material testing into numerical simulation, hence the name material testing integrated (MTI) simulation. The new MTI simulation is validated using large-scale experimental testing.
