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 ...

A framework to automate the design of digitally-fabricated timber plate structures

Yves Weinand, Petras Vestartas, Nicolas Henry Pierre Louis Rogeau, Aryan Rezaei Rad, Henry V. Burton

The current study uses knowledge from digital architecture, computer science, engineering informatics, and structural engineering to formulate an algorithmic framework for integrated Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) of Integ ...

Research on a New Class of Planar Tensegrity Trusses Consisting of Repetitive Units

Yafeng Wang

Tensegrity structure is a prestressed self-equilibrated system consisting of compressed struts and tensioned cables. Planar truss is one of the most common forms of engineering structures with a wide application. This paper proposes a new class of planar t ...

Experimental Testing of a Small-Scale Truss Beam That Adapts to Loads Through Large Shape Changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

Adaptive structures have the ability to modify their shape and internal forces through sensing and actuation in order to maintain optimal performance under changing actions. Previous studies have shown that substantial whole-life energy savings with respec ...
