To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model for wood joints and structural systems that is based on a modified endochronic theory. This model incorporates experimentally observed characteristics such as nonlinearity, strength and stiffness degradation and pinching and is in a form suitable for both deterministic and random vibration analyses. Its capability is demonstrated under cyclic loading.
