The light steel frame walls are mostly used for non-load bearing applications. The light steel framed walls are made with studs and tracks that require fire protection, normally achieved by single plasterboard, by composite protection layers or by insulation of the cavity. The partition walls are fire rated to resist by integrity and insulation. Seven small-scale specimens were tested to define the fire resistance of non-load bearing light steel frame walls made with different materials. All tests were validated using two-dimensional numerical models, based on the finite-element method, the finite-volume method and hybrid finite-element method. A good agreement was achieved between the numerical and the experimental results from fire tests. The fire resistance increases with the number of studs and also with the thickness of the protection layers. The hybrid finite-element method solution method looks to be the best approximation model to predict fire resistance.

复合非承重轻钢框架墙的耐火性能

轻钢框架墙主要用于非承重应用。轻钢框架墙由需要防火的螺柱和轨道制成，通常通过单个石膏板、复合保护层或空腔绝缘来实现。隔墙具有防火等级，可通过完整性和绝缘来抵抗。测试了七个小型试样，以确定用不同材料制成的非承重轻钢框架墙的耐火性。所有测试均使用二维数值模型进行验证，基于有限元方法、有限体积方法和混合有限元方法。数值和火灾试验的实验结果之间取得了很好的一致性。耐火性随着螺柱的数量和保护层的厚度而增加。
