Robustness Analysis of Historical Timber Roofs: A Case Study of the Gaggiandre Shipyard at the Arsenale of Venice

In this work, a deterministic approach is adopted to analyze the robustness of timber roof Gaggiandre shipyard at Arsenale Venice. The capacity traditional truss withstand design loads as result damage in strut-tie node evaluated according alternative load path method. Two layouts trusses are analyzed and compared: before after Austrian retrofitting intervention, performed late 1800s. For both configurations, analyses carried out by using linear 2D numerical models that consider effective rotational structural nodes relation construction methods joints. configuration subject 19th-century restoration, 3D response also verify additional contribution provided longitudinal bracing system activation paths (bridge effect). results obtained with different thoroughly evaluated, providing an indication index roofing based on assumptions. outcomes work allow draw some general considerations method could be used for assessment historical wood systems.
