Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and other factors are considered. A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment.

Superimposed on the averaged winds are gusts whose aggregation, for short periods of time ranging from fractions of seconds to a few seconds may move at considerably higher speeds than the averaged winds.

Design pressures based on wind speeds with a mean e18886 interval usually 25 to years that relates to desired levels of structural reliability and are appropriate for the type and importance of the building 1.

The damage caused by windborne debris during windstorms goes beyond failure of building envelope components such as windows, doors, and curtain walls.

Other test methods, such as Test Methods E and E, do not model gust loadings. Specific hazard statements are given in Section asmt.

The latter approach reduces the likelihood of exposing the building contents to the weather. Link to Active This link will always route to the current Active version of the standard.

Breaching of the envelope exposes a building’s contents to the damaging effects of continued wind and rain 1, They are not to be specified for the purpose of testing the adequacy of xstm assembly to remain unbreached in a windstorm environment following impact by windborne debris.

The resistance of fenestration or impact protective systems assemblies to wind loading after impact depends upon product design, installation, load magnitude, asmt, and repetition. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The missiles and their associated velocity ranges used in this test method are selected to reasonably represent typical debris produced by windstorms. Specific hazard statements are given in Section 7.

Typical debris in hurricanes consists of missiles including, but not limited to, roof gravel, roof tiles, signage, portions of damaged structures, framing lumber, roofing materials, and sheet metal 4, 7, 9. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm. When the windward wall of a building is breached, the internal pressure in the building increases, resulting in increased outward acting pressure on the other walls and the roof.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Thus, there are two options in designing buildings for windstorms with windborne debris: The actual in-service performance of fenestration assemblies and impact protective systems in areas prone to severe windstorms is dependent on many factors. It is appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm.

This test method is applicable to the design of entire fenestration e18886 impact protection systems assemblies and their installation. As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused a significant amount of damage to building envelopes This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation.

ASTM E – Farabaugh Engineering and Testing

Windstorm damage investigations have shown that the effects of windborne debris, followed by the effects of repeated or cyclic wind loading, were a major factor in building damage However, if doors and windows and their supports are designed to resist specified loads and the glass is protected by a screen or barrier, they need not be considered openings.

Gust wind loads are of relatively short duration. A potentially more serious result is internal pressurization. However, these test methods do not account for other factors such as impact from windborne debris followed by fluctuating pressures associated with a severe windstorm environment.

This can increase the net outward acting pressure by a astk as high as two. A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment.
