Structural performance depends on load and resistance parameters, in particular, magnitude and frequency of load components and their combinations, the strength of materials, modulus of elasticity, dimensions, rate of deterioration, and so on. The problem is that these parameters are time-varying random variables and the structure is expected to perform its function in an acceptable manner. Therefore, the prediction of structural performance involves uncertainty. Reliability is defined as a probability of the structure to acceptably performing its function. There is a need to determine the optimum or target reliability level, as too low reliability can result in problems (e.g. cracking, vibrations, collapse) and too high reliability can be costly. The slides in this presentation deal with the selection criteria for the target reliability.
