No peril can match the wind of a severe tropical storm (hurricanes, typhoons and cyclones) in its ability to cause widespread devastation.
在造成广泛破坏的能力上，没有任何危险能够与严重的热带风暴（飓风，台风和旋风）相媲美。

With proper knowledge and preparation extensive wind damage can be avoided - even in the most severe storms. We can identifie areas in a building that are most vulnerable to damage, and how to adequately reduce the risk. We can help you understand the risk that this hazard represents to your business.
有了适当的知识和准备，就可以避免大范围的风灾-即使在最严重的暴风雨中也是如此。我们可以确定建筑物中最容易损坏的区域，以及如何充分降低风险。我们可以帮助您了解这种危害对您的业务造成的风险。

The costliest impact of these storms is the damage that results when the build- ing’s envelope is torn open and lets wind and rain into the facility. Below are the most frequent and damaging ways that the building envelope can be opened:
1.Roofing covering and insulation tear up and off from support members.
2.Lightweight wall covers such as exterior insulating finishing systems (EIFS) or aluminum panels tear away from the structure.
3.Windows are broken by windblown debris, such as surrounding trees or gravel from nearby roofs.
4.Windows are blown in by the pressures exerted on the building.
During a windstorm, damage to the building’s structural frame seldom occurs. Yet by comparison, a very small breach in the building envelope can destroy a large area of the interior. For this reason, keeping the building envelope sealed is one of the most effective ways of preventing windstorm damage at your facility.
这些风暴造成的最严重的影响是建筑物外壳被撕开并让风雨淋进设施时造成的损坏。以下是打开建筑物围护结构的最常见和最具破坏性的方法：
1.屋顶覆盖物和绝缘材料从支撑部件上脱落。
2.轻质的墙壁覆盖物，例如外部绝热整理系统（EIFS）或铝面板会从结构上撕下。
3.窗户被飞扬的碎屑弄碎，例如周围的树木或附近屋顶的碎石。
4.窗户被建筑物上的压力吹进来。
在暴风雨期间，很少会损坏建筑物的结构框架。但是，相比之下，建筑物围护结构中很小的缺口会破坏大面积的内部空间。因此，保持建筑围护结构密封是防止设施遭受暴风雨破坏的最有效方法之一。

Keeping the building envelope in one piece through a storm is a simple matter of wind resistance. If the roof, walls and windows can withstand forces exerted by wind and wind-borne debris, your facility will survive.
在暴风雨中将建筑物围成一个整体是一个简单的抗风性问题。如果屋顶，墙壁和窗户能承受风和风吹碎屑所施加的力，则您的设施将可以幸存。

There are two important lessons to take from this:
1.Wind acts in different parts of the building in different ways. The small corner and edge areas of the roof experience significantly more pressure and are often the first to fail. These areas need to be well-secured. Since they are small areas, and we are talking about a few additional fasteners in most cases, enhancement is normally rather inexpensive.
2.Ensure that the pressures your facility is designed to withstand are realistic and give you a feeling of comfort for the life of the plant. Life safety-based design codes most often design for a windspeed that is likely to be exceed- ed while your facility is still standing. Use code wind maps as a starting point and then apply common sense based on history.
有两个重要的经验教训：
1.风以不同的方式作用于建筑物的不同部分。屋顶的小角落和边缘区域承受的压力要大得多，并且通常是第一个失效的区域。这些区域需要妥善保护。由于它们的面积很小，并且在大多数情况下我们都在谈论一些其他的紧固件，因此增强通常很便宜。
2.确保您的设备设计承受的压力是现实的，并为您的工厂寿命提供舒适的感觉。基于生命安全的设计规范最经常针对风速进行设计，而您的设施仍处于静止状态时，风速可能会被超过。使用代码风向图作为起点，然后基于历史应用常识。
