Abstract

The implementation of reliability methods for designing new structures and assessing the safety and evaluating the performance of existing structures and infrastructure systems has gained widespread acceptance. Most importantly, reliability-based design specifications presented in the form of the Load and Resistance Factor Design (LRFD) method have dominated the development of current generation codes and standards. This paper and the accompanying paper entitled “reliability-based performance indicators for structural systems and networks” compare the reliability-based performance indicators and criteria used by different agencies to calibrate existing structural design and evaluation codes and standards for different types of structures under service load and man-made or natural extreme hazards. The papers also review reliability measures that have been used or proposed for evaluating the safety and serviceability of individual components, structural systems, and infrastructure networks. Specifically, this review examines how the following issues are considered: (1) component strength; (2) fatigue resistance; (3) serviceability; (4) structural system performance including vulnerability, redundancy, robustness, progressive collapse, risk, and resilience; and (5) performance of lifeline systems and networks. A brief review of how time-dependent changes affect the life cycle performance of systems is also presented. This paper focuses on the reliability of individual members under common permanent and transient loads as addressed in design codes and standards. The accompanying paper addresses the reliability of entire structural systems and infrastructure networks.
