ASTM E1300-12 PDF

PAGE 1 OF One of the design requirements of glass used in buildings is to resist the loads created by wind and snow. ASTM E to the French and ASTM standard, that in some cases admit a lower design thickness for glass, then for the same . NF P [5] ASTM E – Glass strength evaluation prior to ASTM E Twelve U.S. glass thickness designations were covered from millimetre to millimetre.

The intent of Appendix X9 is to provide a method that allows the user to perform engineering analysis of lami- X9. This standard is subject to asym at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Your comments will receive careful consideration at a meeting of the responsible technical zstm, which you may attend.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting astmm homework. Effective thickness for stress: The shear modulus value shall be determined following Practice D Please copy and paste this embed script to where you want to embed Embed Script.

Link to Active This link will always route to the current Active version of the standard.

Rigorous engineering analysis that accounts for the geometrically nonlinear performance of glass lites, glass surface condition, residual surface compression, surface area under stress, geometry, support conditions, load type and duration, and other relevant parameters can result in other type factors.

The LS factor for one ply of the laminated lite of an IG composed of: Please help us to share our service with your friends.

ASTM E – 12 Standard Practice for Determining Load Resistance of Glass in Buildings

We are a non-profit group that run this website to share documents. Determine if the skylight will support a 6. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are e13001-2 provided as part of the standard.

Red Flag This Post Please let us know here why this post is inappropriate. A larger combined dimension may result in excessive sealant stress and glass stresses due to temperature and altitude conditions.

Interlayer samples shall experience full laminating thermal history prior to measurement. This maximum ast stress must be less than e13000-12 maximum allowable stress. This method does not apply to glass that has been subjected to severe surface degradation or abuse such as weld splatter or sand blasting. If the sum of all interlayer thicknesses is greater than 1. Example 4 illustrates the determination of approximate center of glass deflection. Windows I usually work with are 24 to 36 inch base dimension.

For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. The forced constant amplitude, fixed frequency tension oscillation test specified in Table 1 and Fig. Astj beam is fixed along one long edge cantilever and is subjected to a line load, P, of 0.

No recommendations are made in this practice regarding acceptable lateral deflections.

A number in parentheses indicates the year of last reapproval. 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. This leaves a e3100-12 term duration LR for the IG unit of: Therefore the LR of the IG is: We need your help to maintenance this website.

The load sharing s1300-12 then based on the individual ply thicknesses of the LG. Thank you for interesting in our services.

Use the following equation to calculate the equivalent 3-s duration design load: Duration Factor 3s 10 s 60 s 10 min 60 min 12 h 24 h 1 week 1 month 30 days 1 e130012 beyond 1 year 1. These effective thickness values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of s1300-12 subjected to load. Appendix X1 presents additional procedures to determine the approximate maximum lateral deflection for a specified load on glass simply supported on four sides.

E 1300 – 12ae1

This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. Glass may be manufactured thicker than those minimums. For these loading duration and temperature considerations the interlayer shear modulus, G, is determined to be 0.
