Optimal Calculation of Non-Probabilistic Structure Reliability Index

Article Preview

Abstract:

The optimal calculaion of non-probabilistic structure reliability index is researched, where the minimum distance from the origin to the limit-state surface in the standard normal space is required. From the viewpoints of the global nolinear and local linear, it build the global approximate variational inequality. The primal coupled potential function is used to decide direction and step of searching. It is more effective in convergence and polynomials than the other methods in the related references. After a brief review, the method are compared through two numerical examples. It shows that the present method is effective and feasibility.
