Dynamic behaviour and instability of tubular metal scaffolding under high gravity loads

Abstract

Loading scaffolding at significant heights renders them unstable. No rigorous and reliable measure of scaffolding stability exists.

Digital analysis of dynamic instability, and laboratory tests were used to characterize scaffolding structure.

A mathematical model of scaffolding stability was developed. The length of extensions exerts a sizeable influence on scaffolding resistance.

The results of this project may be used to establish safer and more objective standards for scaffolding construction and use, and detailed construction criteria may be developed.
