Scientists at EPFL have developed new methods to design and control civil structures that are able to automatically adapt to loading. The aim is to reduce the environmental impact of the construction sector.<\/p>\n

In order to address current environmental challenges, the construction industry must find new ways of building. “The construction industry is the largest consumer of raw materials and accounts for over a third of global energy demand,” says Gennaro Senatore, a scientist at ENAC’s App<\/a>lied Computing and Mechanics Laboratory (IMAC) and lead of the research project. “Built environments are responsible for up to 40-50% of total CO2<\/sub> emissions throughout their service life.”<\/p>\n

That remarkably high figure is partially due to traditional design practices applied to most civil engineering structures. Civil structures are typically designed to withstand worst-case loading events\u2014which in practice occur very rarely: strong winds, earthquakes, snowstorms and large crowds.<\/p>\n

A solution lies in adaptive structures, which are able to adapt to ensure that strength and serviceability requirements are met against changing loading conditions. “Adaptive structures can operate closer to design limits, which means they can perform better and in a more sustainable way than conventional passive structures,” explains Senatore.<\/p>\n

The design criterion adopted in this work is minimization of structures whole-life energy requirement, which includes energy used for operation, such as for sensing, control and actuation during service as well as energy used for materials and construction\u2014known as embodied energy.<\/p>\n
