Scaling Laws in Progressive Collapse Studies

Elkady, Nada; Augusthus-Nelson, Levingshan; Weekes, Laurence

Abstract

This state-of-the-art study introduces an innovative approach employing scaling laws to facilitate the utilisation of small-scale models in progressive collapse experimentation. It evaluates the quasi-static behaviour of scaled beam-column sub-assemblies, utilising a geometric scaling ratio of 1:4 to simulate column loss scenarios, which were subsequently validated against a full-scale prototype. The findings derived from the scaled models demonstrate a strong correlation with the prototype data, thus affirming the successful applicability of scaling laws in progressive collapse investigations. The application of this concept can help accelerate the experimental research of progressive collapse due to its expedited and cost-effective nature and thus help reshape the current understanding of progressive collapse effectively.
