Numerical modelling and fire testing of gypsum plasterboard sheathed cold-formed steel walls

Eco-efficient thermoacoustic panels made of totora and gypsum for sustainable rural housing ceilings

“…Several authors have studied the use of gypsum in combination with organic materials, such as incorporating wood waste into the gypsum matrix, for the development of false ceiling boards with improved thermal and acoustic properties (24). Gypsum boards are used in walls or ceilings with light gauge steel structure as the main fire-resistant material, in addition to thermal protection (25). Low thermal conductivity values for gypsum of 0.17 W/m•K have been recorded, indicating that it behaves as a good thermal insulator (26).…”

Systematic literature review of cold-formed steel at elevated temperature scenario

“…Abeysiriwardena and Mahendran investigated the influence of out-of-plane restraints given by plasterboard sheathing using a single stud FEA model with simplified boundary conditions and concluded that the FRL of the walls is considerably enhanced by the out-of-plane restraints provided by gypsum plasterboard with 16 mm thickness. Their research has also established suitable out-of-plane restraint values recommended for use in the numerical analysis of walls with single and double plasterboard sheathings [ 77 ]. Tao et al presented an FEA modeling of LSF walls using ANSYS to study the benefit of utilizing RHS/SHS studs walls that are cavity insulated and to investigate whether steel quality and stud depth could alter the LSF walls' fire resistance capacity.…”
