ABSTRACT
Since 1961, a large number of experimental, theoretical and numerical studies have been carried out to produce an equivalent strut model for infillframe structures.
The geometric properties of such strut(s), viz. the number of struts, total cross sectional area of strut(s), and the location of strut(s), relate to how the infill panel and frame structurally interact, and hence the contact area between the two at different levels of loading/drift.
