Cross entropy weight minimization of a compressive strut
| Title: | Cross entropy weight minimization of a compressive strut | Authors: | O'Brien, Eugene J.; Malekjafarian, Abdollah; Micu, Alexandra | Permanent link: | http://hdl.handle.net/10197/9245 | Date: | 19-May-2016 | Online since: | 2018-02-21T16:05:31Z | Abstract: | In this study, a population-based optimization algorithm is used to minimize the weight of a compressive strut. A geometrically nonlinear analysis is carried out to get an accurate measure of the structure's true capacity, allowing for individual member and overall structure (and sub-structure) buckling. To overcome the computational challenge of nonlinear analysis, the study uses a simple definition of the onset of instability and hence the number of iterations is cut to a minimum. | Funding Details: | Science Foundation Ireland Enterprise Ireland |
