Reliability of timber structural system under seismic loading

The objective of this research program is to develop fundamental understanding and analytical tools to study the reliability of woodframe and post & beam building systems under seismic loading.Reliability based assessment as a means to define the performance of timber structures is a goal recognized by design code committees worldwide.  Its application is particularly suited to timber structures under earthquake loadings as the material properties of the timber, the seismic event, and the generated lateral forces are highly random.  The proposed work will focus on the development of a database to study the performance and damage of more realistic taller and irregular timber buildings including: 1) the "stiffness" of floor (with perforations) and roof diaphragms; 2) the performance of taller walls with or without perforations; and 3) the 3-dimensional structural behaviour of full size taller structures.  Models linking the semi-rigid diaphragm to the UBC pseudo nail wall analysis tool will be developed; the model will be calibrated and verified against test data, and reliability assessment on the seismic response of more realistic structures will be conducted by using either a fragility or response surface approach.
