The first-order reliability method, (FORM), is a semi-
probabilistic
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, ...
reliability analysis method devised to evaluate the reliability of a system. The accuracy of the method can be improved by averaging over many samples, which is known as
Line Sampling.
The method is also known as the Hasofer-Lind Reliability Index, developed by Professor
Michael Hasofer and Professor
Neil Lind in 1974. The index has been recognized as an important step towards the development of contemporary methods to effectively and accurately estimate structural safety.
The analysis method depends on a "Most Probable Point" on the limit state
