ACTIONS IMPOSED ON STRUCTURES DURING MAN‐MADE ACCIDENTS: PREDICTION VIA SIMULATION‐BASED UNCERTAINTY PROPAGATION

Uncertainty Analysis of Structures via Semidefinite Program

Assessment Measures in Uncertainty Propagation Analysis Applied to Composite Structures

The uncertainty propagation of composite structures is investigated considering descriptive statistical measures of the response variability. A study based on sensitivity to uncertainty that allows selecting the important parameters using sensitivity indices is presented. The uncertainty propagation and the importance measure of input parameters are analysed using four different approaches: a f...

Self-Imposed Constraints on Collective Action Under Uncertainty

Under what conditions does, or should, a collective of rational individuals support the imposition of a binding constraint on their own collective action? Our innovation is to allow citizen-taxpayers in a standard political economy model to be risk-averse and uncertain about the future average cost of the collective good, their own future income or wealth, and the future distribution of the tax...

Uncertainty propagation or box propagation

This paper discusses the use of recently developed techniques and software in the numerical propagation of uncertainties in initial coordinates and/or parameters for initial value problems. We present an approach based on several validated numerical integration techniques but focusing on the propagation of boxes. The procedure uses a multivariable high order Taylor series development of the sol...

Multifidelity Uncertainty Propagation via Adaptive Surrogates in Coupled Multidisciplinary Systems

Fixed point iteration is a common strategy to handle interdisciplinary coupling within a feedback-coupled multidisciplinary analysis. For each coupled analysis, this requires a large number of disciplinary high-fidelity simulations to resolve the interactions between different disciplines. When embedded within an uncertainty analysis loop (e.g., with Monte Carlo sampling over uncertain paramete...
