Abstract

This chapter delves into the numerical study of U-shaped metallic yielding dampers made from shape memory alloys (SMA-UD) under cyclic loading, focusing on their performance and validation through finite element analysis. The study employs two sophisticated tools, ABAQUS and SAP 2000, to simulate and compare the behavior of SMA-UD, providing a robust framework for understanding their seismic resilience. Key topics include the working principles of both active and passive SMA-UDs, the detailed numerical modeling process, and the validation of results against experimental data. The chapter also highlights the energy dissipation capabilities and ultimate force generated by SMA-UD, offering a comprehensive analysis of their performance under cyclic loading. The findings demonstrate stable flag-shaped hysteresis loops and excellent self-centering abilities, making SMA-UD a promising solution for enhancing the seismic performance of structures. This detailed exploration of SMA-UD behavior provides valuable insights for professionals seeking to integrate advanced damping systems into their structural designs.
