RELIABILITY-BASED DESIGN CRITERION OF STEEL MEMBER [II]

Reliability-Based Optimal Design of Steel Box Structures. II: Ship Structure Applications

Traditional design of ship structures relies on a combination of experience, sound judgment, and deterministic approaches and typically ignores the potential for design improvement and other benefits offered through the use of reliability methods and structural optimization strategies. Part I of this article outlines the underlying theories involved in incorporating reliability methods and stru...

Design of Reliability Insurance Scheme Based on Utility Function for Improvement of Distribution Grid Reliability

The regulatory schemes currently used for reliability improvement have weaknesses in the provision of quality services based on the customers’ perspective. These schemes consider the average of the service as a criterion to incentivize or penalize the distribution system operators (DSOs). On the other hand, most DSOs do not differentiate electricity services at the customer level, due to the st...

PERFORMANCE-BASED DESIGN OPTIMIZATION OF STEEL MOMENT FRAMES

This study deals with performance-based design optimization (PBDO) of steel moment frames employing four different metaheuristics consisting of genetic algorithm (GA), ant colony optimization (ACO), harmony search (HS), and particle swarm optimization (PSO). In order to evaluate the seismic capacity of the structures, nonlinear pushover analysis is conducted (PBDO). This method is an iterative ...

Optimization of Random Sample Size in Progressively Type II Censoring based on Cost Criterion

So far censored samples have been studied by many researchers. One of the most important methods of censoring is progressively type II censoring. An interesting issue in the discussion of censoring is determination of the optimal sample size. Various factors are influential in determining the appropriate sample size, the most important of which is the sampling cost criterion. In this paper, ass...
