Study of morphogenesis of a large-span roof that satisfies its form design requirements Taking shell thickness into consideration
The computer performance is improving, and the various system optimizations by using the evolutionary computing are developed in recent years(K.Mitsui et al., 2004).Though the forms of large span roofs can be built free, the mechanical performances of the roofs are greatly different according to those forms.Moreover, though the aesthetic sensibility is demanded, the studies of morphogenesis which consider the aesthetic sensibility and mechanical rationality are few.We have been studying about morphogenesis that satisfies aesthetic sensibility and mechanical rationality(K.Tsutsumi,Y.Takeda, 2004).However we evaluated mechanical rationality as the equivalent stress under same roof board thickness, therefore we have not examined whether each element stress satisfies the design specification value or not.Then, the purposes of this study are as follows.1) To develop an idea support morphogenesis system that proposes the form which satisfies the designers image and has minimum volume satisfies specified stress by considering each roof board thickness, using the Genetic Algorithm.2) To analyze variable trend of forms to become optimal forms by changing each roof shell thickness.
