ASTM Standards:2 This practice applies only to monolithic, laminated, or C Specification for Flat Glass insulating glass constructions of rectangular. ASTM E • Provides a conservative glass thickness procedure. ▫ Flat Glass Plates. ▫ Uniform Pressure Loads. • All publicized problems with HS ceramic. a result, some glass sizes may meet ASTM E for a given wind load but not be acceptable due to safety and manufacturing concerns. Note these tables are.

For example, orange, red, yellow and violet colored glasses cannot be produced using standard float technology. IGUs reduce the likelihood of interior condensation forming by providing a thermal barrier between the inside and the outside.

However, some applications can be two-sided support, such as Butt Joint Glazing or sometimes even three-sided or one-sided supports. Accommodating for wind and snow is one of the important upfront considerations in the design and specification process.

The final thickness and type of glass selected also depends upon a variety of other factors see 5.

Glass deflections are to be reviewed. Glass 6mm thick will weigh 2. Tempered glass deflects just as much as annealed glass.

The load share factor, which is the multiplying factor derived from the load sharing between two lites ashm equal or different types or thicknesses. First, the impact of wind and snow on a building can be significant, which is why the design requirements must be followed carefully. This practice assumes that 1 the supported glass edges for two, three, e13000 four-sided support conditions are simply supported and free to slip in plane; 2 glass supported on two sides acts as a simply supported beam; and 3 glass supported on one side acts as a cantilever.


Invalid Email Address Message: Atm specified design load, which is the magnitude in kPa or PSF, of the type and duration of the load that is specified by the building code. The glass type factor, which is the multiplying factor for adjusting the load resistance of different glass types.

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 design load needs to be in psf or kPa. It also weighs the same. For conversion of quantities in various systems of measurements to SI units, refer to SI Basic Design Procedures The assumptions and calculations result in these basic design procedures that should be followed: Tempered glass is four times stronger than regular asgm heat strengthened is just two times stronger.

About The Education Center Resources. The glass has been properly glazed, without any edge damage. IGUs reduce sound transmission and provide quieter interior spaces.

Designing Glass to Resist Wind and Snow Loads

This practice does not address aesthetic issues caused by glass deflection. This practice does not consider the effects of deflection on insulating glass unit seal performance. Historical Version s – view previous versions of standard. There is a multi-step process that must be undertaken to help ensure the glass in your project is able to resist these loads.

ASTM E – 16 Standard Practice for Determining Load Resistance of Glass in Buildings

Appendix X1 and Appendix X2 provide additional procedures to determine maximum lateral deflection for glass simply supported on four sides.

The specified design load shall be used for this calculation. The final thickness and type of glass selected also depends upon a variety of other factors see 5.

The word window comes from a Norse term translated “wind eye”, for “eye on the weather. The number of glass edges supported. This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves.

Start with the glass dimensions and the specified design loading.
