利用FDS软件模拟了不同宽度、不同位置防火封堵下建筑幕墙外保温系统的火蔓延情况，讨论了防火措施抑制火焰传播的有效性，得到了防火构造设计的基准参数。并通过大尺寸窗口火试验测试了防火封堵下两种幕墙保温系统的耐火性能，分析了防火封堵在真实火灾条件下的有效性和可行性，提出了最优的防火构造组合。
利用FDS軟件模擬瞭不同寬度、不同位置防火封堵下建築幕牆外保溫繫統的火蔓延情況，討論瞭防火措施抑製火燄傳播的有效性，得到瞭防火構造設計的基準參數。併通過大呎吋窗口火試驗測試瞭防火封堵下兩種幕牆保溫繫統的耐火性能，分析瞭防火封堵在真實火災條件下的有效性和可行性，提齣瞭最優的防火構造組閤。

The fire spreading on insulation systems with curtain walls under different fire prevention measures was simulated by FDS .Then the effectiveness of fire prevention measures was discussed and the design parameters of fire prevention structure were obtained .Finally ,combustion performance on external insulation systems with curtain walls under different fire prevention measures were tested ,their feasibility and effectiveness under real conditions were analyzed , and the optimal combination of fire prevention structure and its technical requirements were put forward .
