Measures of Structural Reliability
This chapter discusses structural reliability and its safety. The study of structural reliability is concerned with the calculation and prediction of the probability of limit state violation for an engineered structural system at any stage during its life. In particular, the study of structural safety is concerned with the violation of the ultimate or safety limit states for the structure. The traditional method to define structural safety is through a factor of safety. It is well known that observed stresses do not always correspond well to the stresses calculated by linear elastic structural analysis. The 'load factor' A is a special kind of safety factor developed for use originally in the plastic theory of structures. The strength of the structure is determined from the idealized plastic material strength properties for structural members. Another common measure, the return period, was reviewed prior to the introduction of a fully probabilistic measure of limit state violation.
