An Adaptive First-Order Reliability Analysis Method for

The HL-RF algorithm of the first-order reliability method (FORM) is a widely useful tool in structural reliability analysis. However, the iteration results of HL-RF algorithm may not converge due to periodic cycles for some highly nonlinear reliability problems. In this paper, an adaptive first-order reliability method (AFORM) is proposed to improve solution efficiency for some …

Reliability analysis and optimal design under uncertainty

The design of optimal and reliable systems is an objective which is pursued in several fields of engineering. Optimality is expressed in terms of a system cost which needs to be minimized, including the partial costs involved at each instant of the system's life, e.g. construction costs, maintenance costs and costs resulting from potential failures. In addition, the system is …
