Exciting News! Our paper titled "Structural Identification from Operational Modal Analysis: The Case of Steel Structures" is now available! 

We're thrilled to introduce our innovative methodology for structural identification using OMA, featured in this paper. By minimizing the disparity between experimental and theoretical eigenfrequencies, through simulated annealing, we've unlocked a powerful tool for enhancing structural knowledge while minimizing any potential impact on the structure itself and its operations.

In this paper, we delve into the critical aspects of our methodology, including the modeling intricacies and optimization procedures used to fine-tune unknown parameters. Through validation on various experimental cases, ranging from small-scale steel beams to full-scale steel frames, we've demonstrated its efficacy in assessing crucial structural characteristics like elastic modulus and constraint conditions.

Moreover, we've conducted a comprehensive comparison of heuristic optimization algorithms, showcasing the superior performance of simulated annealing while also highlighting the promising results obtained with alternative approaches.

While computational demands vary based on the complexity of the structure, our methodology offers efficient solutions even for intricate cases, ensuring timely and accurate results.

Looking ahead, we're excited about the potential applications of our methodology in broader contexts, including bridges and buildings, where it can address challenges posed by unknown or unmeasurable parameters, paving the way for further advancements in structural engineering.

Join us in exploring the possibilities of sound pressure and laser doppler vibrometer techniques for modal parameter measurements, pushing the boundaries of structural analysis and optimization.
