对飓风安德鲁直接影响下的多层建筑的玻璃系统行为进行了集中调查。在1992年8月26日至8月30日期间，对17栋建筑物和4个建筑群进行了检查。调查的建筑从北部的迈阿密到南部的Cutler Ridge，跨度为32公里(19英里)。除了少数例外，玻璃系统的性能很差，对建筑内容的破坏很大。具体的观察结果如下：(1)风吹碎屑的撞击是玻璃失效的主要原因；(2)墙体系统锚固有时会失效；(3)防止内部加压后的“穿透”显著减轻了风暴对建筑内部的破坏；以及(4)一些中空玻璃单元发生了仅外墙失效。调查结果强调了在严重风暴期间保持建筑物围护结构完整性的重要性。在设计建筑玻璃系统时，必须考虑风带来的碎片，也必须考虑将玻璃系统适当地固定到建筑框架构件上。
A focused survey of glazing system behavior in multi-story buildings in the direct aftermath of Hurricane Andrew was conducted. Seventeen buildings and four building complexes were examined between 26 August and 30 August, 1992. The buildings surveyed spanned a 32 km (19 mile) distance from Miami on the north to Cutler Ridge on the south. With few exceptions, glazing systems performed poorly and damage to building contents was extensive. The following specific observations were made: (1) impacts from windborne debris were a dominant cause of glass failure; (2) wall system anchorages sometimes failed; (3) prevention of ‘blow-through’ after internal pressurization significantly mitigated storm damage to building interiors; and (4) outer-lite-only failures occurred on some insulating glass units. Results of the survey underscore the vital importance of maintaining the integrity of a building envelope during a severe windstorm. Windborne debris must be considered in the design of architectural glazing systems, as must proper anchorages of glazing systems to building framing members.
