COMSOL Multiphysics Implementation of SMA Bracing for Multi-story Structure

Wasilewski, Kacper / Zbiciak, Artur

This article describes the implementation of a material model of shape memory alloy (SMA) in COMSOL Multiphysics software. Authors discuss different possibilities of modeling SMA within this system and present the approach that is continuation of their previous work. The behaviour of material is described with a set of explicit differential equations that derive from the rheological scheme of the SMA. The equation interpreter within the software allows straightforward implementing equations to the Partial Differential Equation Module coupled with Structural Mechanics Module. This modeling strategy was illustrated with analysis of a five-story steel frame subjected to the Loma Prieta earthquake. The structure was equipped with buckling resistant braces with SMA dampers. Due to the unique characteristic of superelasticity this kind of dampers enhance performance of the setup. Presented results show the benefits of the approach to material modeling by using rheological schemes and possibilities of its application within a commercial software.
