Design for Structural Reliability

Reliability - based Structural Design

Reliability based structural design

According to ISO 2394, structures shall be designed, constructed and maintained in such a way that they are suited for their use during the design working life in an economic way. To fulfil this requirement one needs insight into the risk and reliability under expected and non-expected actions. A key role in this respect is played by the structural reliability analysis (SRA). In this paper the ...

Methods for reliability based design optimization of structural components

Cost and quality are key properties of a product, possibly even the two most important. One definition of quality is fitness for purpose. Load-bearing products, i.e. structural components, loose their fitness for purpose if they fail. Thus, the ability to withstand failure is a fundamental measure of quality for structural components. Reliability based design optimization (RBDO) is an approach ...

ENHANCING WEIGHTED UNIFORM SIMULATION FOR STRUCTURAL RELIABILITY ANALYSIS

Weighted Uniform Simulation (WUS) is recently presented as one of the efficient simulation methods to obtain structural failure probability and most probable point (MPP). This method requires initial assumptions of failure probability to obtain results. Besides, it has the problem of variation in results when it conducted with few samples. In the present study three strategies have been present...

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...
