Robust improvement of the finite-element-model updating of historical constructions via a new combinative computational algorithm
(Elsevier, 2024-04)
Finite-element-models are usually employed to simulate the behaviour of historical constructions. However, despite the high complexity of these numerical models, there are always discrepancies between the actual behaviour ...
