Ponts et charpentes Résumé : Current research trends in residential construction focus on the development of performance-based design methodologies for wood structures. As one key prerequisite to the implementation of such design concept, the performance objectives and their corresponding limit state criteria must be properly defined first. So far, the displacement-based limit state criterion, such as the one proposed in ASCE 41, is the only type of standard available for wood structures. In this paper, damage index-based limit state criterion is proposed for wood-frame buildings. The Park-Ang damage model is used to estimate damage to the wood structures caused by seismic loads. An incremental dynamic analysis-based approach is developed to calibrate the damage model parameter for wood shear wall. To predict the potential damage of wood-frame buildings under future earthquakes, the relationship between calculated damage index and observed building damage is established and validated by experimental test data. The results of this research show that displacement alone may not be a reliable indicator for seismic performance of wood structures and damage index-based criterion allows a more realistic performance evaluation.
