Extension of Generalized Bouc-Wen Hysteresis Modeling of Wood Joints and Structural Systems
A critical analysis of the hysteresis models of wooden connections has led to an alternative analytical formulation of the pinching phenomenon. Starting from the generalized Bouc-Wen model, the six-degrees-of-freedom formulation has been extended to an eight parameters formulation, which is a better representative of the connection’s cyclical degradation. The information given by the two additional parameters and also energy-dependency of the parameters provide a faithful representation of the actual hysteresis cycles of wooden connections. The model has been calibrated on experimental data, following an identification procedure, based on an Ordinary Least Squares (OLS) operator.
