Bridge Maintenance and Management | Lecture 4 | Structural Reliability and Quality

The aim in structural reliability analysis is calculation of failure probability in which failure is defined as violation of limit state function.
Structural systems and approaches to estimate their reliability, depending on the configuration of the system. When carrying out structural reliability analysis, appropriate safety levels should be selected based on factors like consequence of failure, relevant rules, access to inspection and repair, etc. Strictly speaking, all variables in engineering structures are stochastic to a certain degree. Structural reliability analysis deals with the rational treatment of random variables and uncertainties within structural engineering designs, inspections, maintenance, and decision-making.
