System reliability developments in structural engineering

TL;DR: In this paper, the effects of damage and redundancy on the reliability of structural systems are investigated based on a definition of structural redundancy including both system reliability and damage assessment concepts, and the results are used to develop the theoretical concepts and to illustrate their practical applications.

TL;DR: In this article, the authors proposed a methodology to apply Bayesian networks to structural system reliability reassessment, with the incorporation of two important features of large structures: (1) multiple failure sequences, and (2) correlations between component-level limit states.

TL;DR: In this paper, a generalised framework for assessing bridge life-cycle performance and cost, with emphasis on analysis, prediction, optimisation and decision-making under uncertainty, is briefly addressed, and a number of significant developments are summarised, including time-variant reliability, risk, resilience and sustainability of bridges, bridge transportation networks and interdependent infrastructure systems.

TL;DR: In this paper, a short program code in the ubiquitous Excel spreadsheet platform for efficiently calculating the bounds for system failure probability is provided for a semi-gravity retaining wall with two failure modes, a soil slope with two and eight failure modes and a loaded beam with three failure modes.

TL;DR: In this article, a simple geometrical interpretation of the correlation between mode safety margins combined with a well-known geometry interpretation of single mode reliability index makes the practical calculation of the system reliability bounds easy, particularly when the set of basic variables is jointly normally distributed.

TL;DR: In this paper, the reliability of a complex structural system with mutually dependent modal resistances and load distribution is derived for general conditions of modal resistance and load distributions including time-dependent cases.

TL;DR: In this article, the reliability analysis of structural components is extended from structural elements to structural systems, and techniques for calculating the reliability or probability of failure of complete structural components are developed.

TL;DR: A matrix formulation of the reliability analysis and reliability-based design of structures is developed and can be used by designers to choose among alternative designs that satisfy all existing code regulations, and to design systems in the absence of formal code regulations.
