Adaptive Cable Dome
Publication: Journal of Structural Engineering
Volume 141, Issue 9
Abstract
This paper describes a newly developed Levy form adaptive cable dome, which has the ability to alter its stiffness configuration and stress properties to adapt its behavior to current loading conditions. This novel structure contains sensors that detect forces in the system and an action member that adjusts its stiffness and stress state, making the structure more rigid or flexible, depending upon the actual load applied. This system consists of 42 tensioned cables, 6 compressed struts, and a central strut that is designed to function as an actuator. Results of the experimental and theoretical analyses are compared. Tests are aimed at verifying the cable dome’s ability to adapt its state of stress to changing load cases to maintain the reliability of the system. Tests confirmed the functionality of the developed adaptive system and the applicability of the proposed equipment, software, computational models, and control commands. Results demonstrate that the behavior of the adaptive cable dome obtained by tests generally can be closely predicted numerically with nonlinear finite element analyses.
