Abstract

The use of commercial software for the analysis of structures has generally been limited to deterministic and linear behavior. In large part, this has been due to a lack of suitable finite elements for the hysteretic components that so often govern the overall response of structural systems. Contributing factors for this simplification included limited test data on full-scale system responses and computational power. Recently, advances have been made in the description and sophistication of finite elements describing the hysteretic behavior of connections. These developments coupled with the increasing availability of test data of component and system responses and the continued advances in computational power diminishes the previous impediments for incorporation of this behavior into structural models. The process and results of incorporating a user defined element into commercially available finite element package is documented and compared with modeling approaches of varying sophistication of the hysteretic response. The application of the developed element is demonstrated on wooden structures that typically exhibit such behavior. This single-degree-of-freedom element can be used to model other hysteretic behaviors such as sorption-desorption hysteresis.
