..towards real-time optimization
A good conceptual design of a building under seismic load must be pursue following certain criteria, as explained in Eurocode 8: simplicity, uniformity, symmetry and redundancy, torsional resistance, etc.. The above-mentioned principles allow a good response to seismic load and adequate reliability of the numerical analysis. To take into account this guidelines we developed a plug-ins for Robot, Elipsis.
The plug-ins gets the required information about the building from the model in Robot; the user can select from different models of eccentricity or insert a model from literature. It is possible to run a single analysis on a building and obtain automatically an Excel spreadsheet and export the model in Revit Structure with the results of analysis or start the optimization task and evaluate hundreds solutions.
Preliminary tests on the plug-ins show how, when the building shape became complex, the fast optimization task allow the designer to make better decision in the preliminary stage of the design process and evaluate the impact of different factor on the behavior of the building.
This is the first algorithm for structural analysis developed to take advantage of GPU computing power; towards an high optimization in the algorithm we can evalutate about 5000 design solution in three minutes on an old CoreDuo@2,2Ghz with a Nvidia QuadroFX 570.
