Structural Knotting For Enhanced Lacing Resilience

Abstract Lightweight and tough engineered materials are often designed with three-dimensional hierarchy and interconnected structural members whose junctions are detrimental to their performance because they serve as stress concentrations for damage accumulation and lower mechanical resilience.

This lecture discusses lacing systems used to connect built-up steel structural members. Lacing systems keep the members parallel and equidistant to act as a monolithic unit under loading. Lacing can fail through buckling of the built-up member, buckling of main components, distortion of the section, or failure of lacing members. Design of lacing must prevent these failure modes. Code ...

As we can see from the illustration, Structural Knotting For Enhanced Lacing Resilience has many fascinating aspects to explore.
