SIMULATE REVERSED NON-LINEAR HYSTERETIC RELATIONSHIPS BY FINITE STATE MACHINE
This paper presents the application of Finite State Machine (FSM) theory to the programming of nonlinear hysteretic model simulation software for both known and newly created rules. Reversed nonlinear constitutive simulation of materials and components is crucial for the analysis of structures under strong earthquake forces. However, complicated reversed internal paths, which not only depend on material properties, but also on load history, often confuse rule creators and scholars. In this paper, we first summary the hysteretic models and their properties and introduce the FSM theory conceptually. Then we explain how it is applied to reversed and diverse hysteresis routes including state definitions and procedures. Two application examples, the Bilinear Model and the Mander Model, are explained with state definition and state diagram. The successful application in UC-win/FRAME(3D) is described too. Finally, several characteristics of the application of FSM to nonlinear simulation are summarized.
