Abstract
This paper demonstrates how adaptive design techniques can be employed to save over 40% of the whole life energy from large scale 3D structures. Using previously developed optimisation methodologies (details published elsewhere) two case studies are investigated: a long span arch bridge and an office tower supported by an exo-skeleton structural system. Assuming some statistical distribution for the occurrence of the loads, the whole energy (embodied and operational) can be minimised by only using activation for large load events. The purpose of the case studies described in this paper is to study: 1) the analysis of performances of adaptive structures in terms of mass and energy savings for both strength and stiffness governed design problems; 2) the scalability of the design process to complex spatial configurations. Both case studies confirmed that even on large complex structures, significant energy savings can be achieved, the more so for stiffness governed structures.
