Concepts for designing stiffer structures


The theory of the design of stiffer structures for building and bridge applications is discussed and the principles illustrated using laboratory models and by considering the design of tall buildings in which these principles have been implemented. The proposed concepts to increase structural stiffness are: more direct internal force paths; more uniform internal force distribution; and smaller internal forces. It is proposed that the use of these concepts may not only increase stiffness but also result in more economical and elegant designs. 13 refs.
