Design Optimization with Variable Screening by Interval-Based Sensitivity Analysis
Publisher: American Society of Civil Engineers
Abstract: Design optimization problems are very common in engineering practice. Determining their solution may be challenging when many design variables are involved. A means to cope with such large number of design variables consists ...
Resilience Assessment under Imprecise Probability
Publisher: ASCE
Abstract: Resilience analysis of civil structures and infrastructure systems is a powerful approach to quantifying an object’s ability to prepare for, recover from, and adapt to disruptive events. The resilience is typically measured ...
Limit-State Function Sensitivity under Epistemic Uncertainty: A Convex Model Approach
Publisher: American Society of Civil Engineers
Abstract: This work proposes a limit-state sensitivity index to identify the input variables of a structure or system which possess a significant impact on its state for the case where the input variables are subject to epistemic ...
Interval Fields for Geotechnical Engineering Uncertainty Analysis under Limited Data
Publisher: American Society of Civil Engineers
Abstract: Spatial uncertainty is a critical challenge in many engineering fields. To date, probabilistic methods have been applied to describe the uncertainty of engineering parameters with considerable achievements. However, they ...
Operator Norm-Based Statistical Linearization to Bound the First Excursion Probability of Nonlinear Structures Subjected to Imprecise Stochastic Loading
Publisher: ASCE
Abstract: This paper presents a highly efficient approach for bounding the responses and probability of failure of nonlinear models subjected to imprecisely defined stochastic Gaussian loads. Typically, such computations involve ...
