Coordinated Control for Flexible Structures and Formwork

Coordinated Control for Flexible Structures and Formwork investigates how to combine the use of flexible elements such as cable-nets, bending-active elements and knitted and technical membranes for use in creating efficient, novel hybrid structures and formwork for concrete. For the latter, creating new, easily deployable and lightweight formwork systems for concrete construction can have many advantages when compared to traditional, stiff or milled formwork solutions, which have high labour and waste costs. These flexible structures gain their stiffness through their geometry and so it is important to carefully control the construction sequence. Methods are sought to accurately measure and control fabrication and erection through efficient numerical analysis methods and robust control algorithms. The project relies on a variety of small- and large-scale demonstrators to prototype and calibrate the digital methods. The collaboration is extending these ideas collectively to design, analyse, fabricate and control new flexible hybrid structures, drawing on the skills of the many different collaborators and fields to successfully realise prototypes and ideas that can be applied directly to construction.
