Abstract: The accumulation of impacts (and local damage) during the extended life-cycle of salvaged timber elements, introduces elevated epistemic and model uncertainty at the component level compared to new components. Existing component-oriented approaches seek to address this through the re-classification of linear salvaged timber elements, aiming to achieve reliability levels equivalent to those of new timber elements. The multi-level approach to structural design with salvaged timber presented in this paper challenges this paradigm. Rather than relying exclusively on the reliability of the individual component, the presented approach complements component re-grading with system level measures. This provides an inherently redundant approach to achieving sufficient structural reliability through the robustness driven design optimization of timber frame structures. The developed multi-level algorithm deterministically conducts component removal scenarios, incorporates Alternative Load Paths and Key Element Design as system level measures, and provides performance indicators of the structure. The investigation of specific aspects of this approach demonstrates that its straightforward, scalable, and automatable algorithmic design framework promotes the reuse of salvaged timber in structural applications, while enabling its integration into complementary digital design frameworks and its adaptation to specific use cases.
