AbstractThis paper presents and discusses the results of gypsum board fall-off time in 80 full-scale fire resistance floor test assemblies using lightweight framed wood joists, wood-I joists and steel joists and wood trusses, protected with either one or two layers of Type X gypsum board. The effects of a number of assembly parameters such as: the number of gypsum board layers; resilient channels installation and spacing; insulation installation and frame type on the gypsum board fall-off time are presented. A comparison of the fire resistance and gypsum board fall-off time for floor assemblies protected with either one or two layers of Type X gypsum board is also presented.
