Seminar - Wei Gao - Non-deterministic analysis and safety assessment of structures with uncertainty

Abstract:
Uncertainties exist in the system parameters when a structure is modelled numerically. For example, the material and geometric properties of a real structure may vary considerably from the design values due to manufacture errors, model inaccuracies, and system complexities. Over the lifetime of a structure, the progressive deterioration of concrete and corrosion of steel usually lead to significant variations of system parameters and performance. Hence, there is no doubt that, for response analysis and proper safety evaluation of structures, uncertainties will need to be taken into account. In this talk, our recent research on hybrid probabilistic and interval analysis of structures, probabilistic dynamic analysis of vehicle-bridge interaction systems and interval limit analysis will be presented.
