Optimal reliability-based design of complex structural systems
Abstract The reliability-based design of structures as a system remains an issue that has not been adequately addressed. Properly, this issue requires the assessment of the system reliability of a complete structure, considering the effects of both thealeatory and epistemic types of uncertainty. The recently developed probability densityevolutionmethod (PDEM) is effective for assessing the effects of the aleatory uncertainty, resulting in the PDF of the critical state of a system. The effects of the epistemic uncertainty maybe included in the system reliability as the potential error of the calculated mean critical stateof thesystem.The result of the PDEM, including the effect of the epistemic uncertainty, is the probability density function (PDF) of the system response. The application of the proposed method is illustrated with the optimal design of three major engineering systems; namely, an offshore oil production platform; a cable-stayed bridge; and a high-rise building under a strong motion earthquake.
