A novel multi-layer jamming (MLJ)-reinforced Tensairity beam for rapid construction in extreme environments

Abstract

Variable stiffness concepts enable structural adaptation to diverse environments, categorized as smart materials or specialized configuration designs. Multi-layered jamming (MLJ) provides a rapid, reversible, and easily controlled actuationmethod. This study examinesMLJ-based variable stiffness components for rapid construction and energy dissipation in civil engineering, focusing on an MLJreinforced Tensairity beam and construction procedure. The numerical model shows the structure's enhanced load-bearing capability post-vacuuming. During large deformation, energy dissipation via interlayer friction produces hysteresis loops, which may benefit to mitigate dynamic responses. While these techniques show promise, challenges exist concerning material limits, application boundaries, quantification, and precise shape control. They could also find utility in environments with confinement pressures like soil or water, expanding the potential applications.
