Abstract

The advances in information technology significantly impact
the engineering design process. The primary objective of this
research is to develop a novel probabilistic decision support
tool to assist management of structural systems under risk and
uncertainty by utilizing a stochastic optimization procedure and
IT tools. The proposed mathematical and computational
framework will overcome the drawbacks of the traditional
methods and will be critically demonstrated through large-scale
structural problems. The efficiency of the proposed procedure
is achieved by the combination of the Karhunen-Loeve
transform with the stochastic analysis of polynomial chaos
expansion to common optimization procedures. The proposed
technology, comprising new and adapted current capabilities,
will provide robust and physically reasonable solutions for
practical engineering problems.
