Design and control of a prototype structure that adapts to loading through large shape changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo, Apoorv Srivastava

This paper reports on experimental testing that was carried out on a prototype adaptive structure designed to counteract the effect of loading through controlled large shape changes. The prototype is 6.6 m truss equipped with 12 linear actuators which has ...

Force and Shape Control Strategies for Minimum Energy Adaptive Structures

Gennaro Senatore, Arka Prabhata Reksowardojo

This work presents force and shape control strategies for adaptive structures subjected to quasi-static loading. The adaptive structures are designed using an integrated structure-control optimization method developed in previous work, which produces minim ...

A new method to design structures that adapt to loads via large shape changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

The construction industry contributes to more than a third of the global energy demand and consumes almost half of all mined material resources. It is thus important to include energy and material efficiency criteria for the design of civil structures. Ada ...
