Cable nets structures exhibit highly non-linear behaviour under applied static loads. Non-linearities are caused by the changes in configuration necessary to equilibrate applied loads and by the slackening and/or yielding of the cables. In order to stiffen such cable net structures and reduce displacements under applied loads the cables are often pretensioned. Such pretensioning, however, requires more substantial cables, stronger connections and stronger supporting structures. It is therefore desirable to be able to design a cable net structure which satisfies all displacement and stress performance criteria with as small a level of pretensioning as possible This paper describes a method which sets the above design problem in a multicriteria optimization context with goals of minimum prestressing force, displacement and stress. A minimax solution is found by means of an entropy-based optimization algorithm. Illustrative examples are solved showing the applicability of the method |
