This special session invites contributions on recent advances in dynamic substructuring and transfer path analysis (TPA) for structural dynamics identification and condition monitoring. The decomposition of complex systems into interacting substructures, combined with force and path reconstruction techniques, has emerged as a powerful framework for understanding, identifying, and monitoring the dynamic behaviour of assembled mechanical and civil structures. Recent developments in substructuring methodologies, inverse identification techniques, operational modal analysis, and hybrid experimental–numerical modelling have significantly expanded the applicability of these approaches under operational conditions. The session aims to bring together theoretical developments, methodological innovations, and practical applications demonstrating the potential of substructuring- and TPA-based approaches for system identification and structural health monitoring.

Topics of interest include, but are not limited to:

• Dynamic substructuring for identification of coupled structural systems
• Transfer Path Analysis for force reconstruction and source–path contribution analysis
• Operational and output-only identification within substructured systems
• Hybrid experimental–numerical substructuring
• Uncertainty quantification in substructuring and TPA
• Substructure-based damage detection and condition monitoring
• Data-driven and physics-informed approaches in dynamic substructuring

Keywords: Dynamic Substructuring, Transfer Path Analysis, Dynamics, System Identification
