| Abstract |
Numerical uncertainties of initial data defined in structures can result in uncertainties of behaviors such as uncertainties of displacement in structural analysis, then directly it may have an influence on qualities of optimal design of structures. In order to evaluate the uncertainties of initial data and structural responses, an interval analysis which investigates the uncertainties utilizing a non-stochastic method is used in this study. In the interval analysis, it is assumed that the numerical uncertainties of initial data are defined as a tolerance error and systematic uncertainties of structures are described by uncertainty combination of initial data.
In this study, the topology optimization design of beam-to-column connectivity is carried out using finite element method with the interval arithmetic and the structural analysis method is proposed. The results are compared with conventional topology optimization results without consideration of the uncertainties. |
