Abstract
AbstractAdaptive structures can modify their geometry and internal forces through sensing and mechanical actuation in order to maintain optimal performance under changing actions. Previous work has...

1.1 Outline This paper presents a new method to design adaptive structures capable of large and reversible shape changes achieved through actuation
This is because large-shape changes allow the structure to effectively redirect the internal forces, minimizing the maximum stress governing the design
Summary
The construction industry is a major contributor to the global energy demand (European Environment Agency, 2010) and a major consumer of mined raw materials (Straube, 2006). For this reason, it is becoming important to design and construct structures taking into account energy and material efficiency throughout their life cycle. Civil structures are generally designed to meet strength and deformation requirements under worst load case combinations, including long-return-period events such as earthquakes and strong winds. The majority of civil structures are overdesigned for most of their service life. The ability to adapt to changing loads enables a structure to operate closer to design limits during service
