Bouc–wen hysteresis

In structural engineering, the Bouc–Wen model of hysteresis is one of the most used hysteretic models typically employed to describe non-linear hysteretic systems. It was introduced by Robert Bouc and extended by Yi-Kwei Wen, who demonstrated its versatility by producing a variety of hysteretic patterns. This … See more Consider the equation of motion of a single-degree-of-freedom (sdof) system: $${\displaystyle m{\ddot {u}}(t)+c{\dot {u}}(t)+F(t)=f(t)}$$ (Eq.1) here, $${\displaystyle \textstyle m}$$ represents the mass, See more Absorbed hysteretic energy represents the energy dissipated by the hysteretic system, and is quantified as the area of the hysteretic force under total displacement; therefore, the absorbed hysteretic energy (per unit of mass) can be quantified as See more The parameters of the Bouc–Wen model have the following bounds $${\displaystyle \textstyle a\in (0,1)}$$, $${\displaystyle \textstyle k_{i}>0}$$ See more Some terms are defined below: • Softening: Slope of hysteresis loop decreases with displacement • Hardening: Slope of hysteresis loop increases with displacement See more Bouc–Wen–Baber–Noori model An important modification to the original Bouc–Wen model was suggested by Baber and Wen (1981) and Baber and Noori (1985, 1986).
