Over the past decades, with the development of modern manufacturing and information technology, demands of smart and economical structural designs have been increasing considerably. Central to this engineering issue is that a good structural design needs to embrace both necessary capabilities to afford critical load distributions and the best arrangement of materials serving the performance criteria using limited resources. Here, a new analysis technique is proposed to achieve optimal structural designs considering peak system responses as design constraints respective to extreme load distributions. We anticipate that the technique will open a door for designing efficient structural systems which satisfy safety requirements under various sophisticated loadings from the environment. ; Tamkang University ; Taiwan Association of Wind Engineering ; Institute of Theoretical and Applied Mechanics, Academy of Sciences of the Czech Republic ; 國際 ; 淡水校園 ; 20151101~20151102 ; Y ; 紙本 ; Y ; New Taipei ; TWN
