Numerical Simulation of Damage on Cementitious Sprayed Fire-Resistive Materials Applied on Steel Plates
(2019)Cementitious Sprayed Fire Resistive Materials (SFRMs) are extensively employed for the fire protection of steel structural members due to their cost-effective fire proofing capabilities. They are susceptible, however, to ... -
On the potential of dynamic sub-structuring methods for model updating
(2019)While purely data-driven assessment is feasible for the first levels of the Structural Health Monitoring (SHM) process, namely damage detection and arguably damage localization, this does not hold true for more advanced ... -
