The proposed method has general applications in probabilistic sensitivity analysis of engineering structures with arbitrary distribution parameters.
Application example The I-beam is widely employed in the practical engineering, such as mechanical engineering, civil engineering and vehicle engineering to provide maximal strength in one direction (usually the direction bearing weight) with a minimal expense of material.
The normal, Gumbel, and Weibul distribution commonly met in engineering problems is considered.
The results show that the proposed method is accurate enough for probabilistic analysis in engineering practice.

The target reliability index is normally determined by using a “calibration method”, combined with engineering judgment.
These coefficients were determined by an expert panel according to related historical data and engineering judgments.

Risk analysis, which is also called reliability analysis, have been put in use in engineering for a long time. 70 years ago, engineers have adapted reliability analysis into the quality monitoring of producing, which developed further in aeronautical engineering, communication engineering (telephone system) and structural engineering [3,4].
In the realm of civil engineering, structural engineers made great achievement in the risk analysis of earthquake and hurricane.
Risk analysis is also studied and put into use in geological technique and water resources engineering.
