Tempered glass deflects just as much as annealed glass. Determination and Report of Procedures. D Practice for Plastics: The load share factor, which is the multiplying factor derived from the load sharing between two lites of equal or different types or thicknesses. Glass 6mm thick will weigh 2.

sstm Work Item s – proposed revisions of this standard. The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are not considered standard. Thermal or insulation improvements achieved with an IGU work day and night in both summer and winter conditions, reducing heat entry and heat loss.
If the load resistance is greater than the specified design loading and the center of glass deflection is reasonable, then the trial design is fine and can proceed.
This practice assumes that 1 the supported glass edges for e3100, three, and 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. Monolithic, laminated and insulating glass constructions made with annealed e11300 heat-treated glass. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides.
Short and long duration uniform loads. This practice assumes that 1 the supported glass edges for two, three, and 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. The 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 single source for information on designing, specifying and building with commercial glass.
This practice does not address aesthetic issues caused by glass deflection. These factors include but are not limited to: This practice does not consider the effects of deflection on insulating glass unit seal performance.
ASTM E – 16 Standard Practice for Determining Load Resistance of Glass in Buildings
The word window comes from a Norse ashm translated “wind eye”, for “eye on the weather. 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 relative strength of glass for a given thickness, width, height and number of supported edges.
Work Item s – proposed revisions e3100 this standard. Glass deflections are to be reviewed.
Invalid Email Address From Name: Active view current version of standard. The final thickness and type of glass selected also depends upon a variety of qstm factors see 5.
The number of glass edges supported. Insulated Glass Units are made with two or more lites of glass with a hermetically sealed space filled with dry air or insulating gas.
Invalid Email Address Message: Pure glass is incredibly strong — it only scratches or breaks because of imperfections that can occur during the manufacturing process.
First, the impact of wind and snow on a building can be significant, which is why the design requirements must be followed carefully. D Practice for E13000 The design load needs to be in psf or kPa. Designing Glass to Resist Wind and Snow Loads Accommodating for wind and snow is one aatm the important upfront considerations in the design and specification process.
Designing Glass to Resist Wind and Snow Loads
D Practice for Plastics: Start with the glass dimensions and the specified design loading. It also weighs the same. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.
Link to Active This link will always route to the current Active version of the standard. Determination and Report of Procedures. A procedure is also presented to calculate the probability of breakage of any annealed lite or ply see Appendix X3for short or long duration loads. In addition, considerations set forth in building codes along with criteria presented in safety-glazing standards and site-specific concerns may control the ultimate glass type and thickness selection.
The resulting load resistance, which is the uniform load that a glass construction can sustain without breaking. This practice is not applicable to any form of wired, patterned, etched, sandblasted, or types of glass with surface treatments that reduce the glass strength.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The procedures operate under some basic assumptions related to glass fabrication and installation, including: It has a light green tint, which can be seen when held against a white background. The final thickness and type of glass selected also depends upon a variety of other factors see 5. The glass type factor, which is the multiplying factor for adjusting the load resistance of different glass types.
