Robustness analysis of structural timber truss systems

Progressive collapse is characterized by disproportion between the magnitude of a triggering event and resulting in collapse of large part or the entire structure. Robustness of structures has been recognized as a desirable property because of a several large system failures, such as the Ronan Point Apartment Building in 1968, where the consequences were deemed unacceptable relative to the initiating damage. After the collapse of the World Trade Centre, the robustness has obtained a renewed interest, primarily because of the serious consequences related to failure of the advanced types of structures. In the introduction different robustness requirements and probabilistic definitions are given. Special attention is given for timber structures. This paper will focus on a robustness of different timber structural systems that are commonly used in designers’ practise (these trusses are calculated according to EC5 for 100% utilization of elements). Comparison of these systems and a conclusion is given.
