Original Abstract

Two approaches to solving the problem of structural design are applied and compared for the particular design problem: the traditional Deterministic-based Structural Optimisation (DBSO) and Reliability-based Structural Optimisation (RBSO), which incorporates probabilistic structural reliability analysis into structural optimisation. This paper focuses particularly on basic RBSO algorithm features and numerical comparisons between RBSO and DBSO algorithms. An example definition of an RBSO problem (conversion from a tereministic to a probabilistic problem) and its solution aare presented on the optimisation of a RC cross-section, which is subjected to the combinations of normal forcce and bending moments. The objective function also includes, besides the total cost of the cross-section, negative environmental impacts. Numerical results for the particular data set are presented.
