Among the elements considered in the procedure are the structural conception, the quality of the timber-to-wall connection, the type and quality of timber-to-timber carpentry joints, and the general state of conservation. Numerical analyses performed for different structural typologies, with geometrical data collected from real cases, constitute the basis for evaluating the structural conception.

Abstract

In the last decades, methods for assessing the seismic vulnerability of different types of structures and infrastructure have been developed. No criteria have been so far developed for timber structures. A methodology for assessing the seismic vulnerability of timber roof structures is described. Among the elements considered in the procedure are the structural conception, the quality of the timber-to-wall connection, the type and quality of timber-to-timber carpentry joints, and the general state of conservation. Numerical analyses performed for different structural typologies, with geometrical data collected from real cases, constitute the basis for evaluating the structural conception. The key points for the evaluation of carpentry joints are the maintenance of connection during alternate excitation and their expected post elastic behaviour. The paper proposes a first version of the method and some application examples.
