摘要：结构中的易碎面板是设计用于足够快地破碎和吹走以限制结构内部爆炸的影响的外表面。与结构的表面相比，典型的易碎面板重量轻。面板连接设计为在结构的任何表面提供很小的阻力。防火板主要用于限制内部爆炸环境，减少碎片对结构外部人员和财产的危害，并将硬化结构内部爆炸的影响以规定的方向排出结构。理想的易碎板是不会增加内部爆炸环境的板。这需要一个无质量的面板，它是冲击波的非反射表面。由于任何壁板都有质量，易碎壁板的设计必须根据具体情况，并在结构设计中考虑其对内部爆炸环境的影响。讨论的主题包括：气体压力载荷;设计载荷和TNT当量。
Abstract : A frangible panel in a structure is an exterior surface designed to break lose and blow away quickly enough to limit effects from an explosion inside the structure. Typical frangible panels are lightweight, compared to the surfaces of the structure. Panel connections are designed to offer little resistance in any surface of the structure. Frangible panels are primarily to limit the internal blast environment, reduce the debris hazard to personnel and property outside the structure, and vent effects of explosions inside hardened structures in prescribed directions away fom the structure. An ideal frangible panel is one that does not increase the internal blast environment. This requires a massless panel that is a nonreflecting surface for shock waves. Since any panel will have mass, frangible panels must be designed on a case-by-case basis and their effects on the internal blast environment accounted for in the design of the structure. Topics discussed include: Gas pressure loading; Design loading, and Equivalent weight of TNT.
