空間骨組構造物の耐カ制御設計法の提案: その1　遺伝的アルゴリズムによる構造性能設計

摘要

大スパン建築を実現する大空間骨組構造物は，一般的に伝達効率の高い軸力抵抗による形態抵抗型の構造物であり，考えられる建築構造システムの中では比較的少ない使用材料で大きな内部空間を獲得することが可能である。しかしその半面，曲げによる抵抗に期待する一般的な梁柱骨組構造とは異なり，構造システムにゆとりを付与することができにくく，結果として脆性的な崩壊に陥り易い構造物となることが多いと言うことができる。%With a recent development of computer technology, various kinds of excellent algorithms have been developed for optimization problem and new concepts in computer science have been successfully introduced into structural optimization such as genetic algorithm, simulated evolution method, simulated annealing method, dynamic tunneling algorithm, Boltzmann machine method, neural net work, artificial life and so on. In the field of structural design, much more attention on those structures with high redundancy has been focused from the viewpoint of safety as well as sustainable structural design, which in general requires a high cost. In this paper, the control design method of structural baring capacity is proposed to realize the low cost structures having precisely aimed baring capacity characteristics by using genetic algorithm (GA) as optimization tool.
