27、 planned to occur during their intended use and to remain serviceable. 4.1.2 As a result of the brittle fracture behaviour of glass, particular structures or installation situations may require sufficient residual load-bearing capacity. 4.1.3 The residual load-bearing capacity of glazing structures
28、depends on the type of structure, the degree of damage and the external actions to be taken into consideration. 4.2 Design by testing Instead of calculated verifications in accordance with the provisions stipulated in this standards series, experimental verifications are also allowed if the procedur
29、e and interpretation of the tests are dealt with by this standard. 5 Construction materials 5.1 Glass 5.1.1 Products For the definition of the terms associated with the products applicable within the framework of this standard, reference is made to the following standards: DIN EN 572-2 for float gla
30、ss; DIN EN 572-3 for polished wire glass; DIN EN 572-4 for drawn sheet glass; DIN EN 572-5 for patterned glass; DIN EN 572-6 for wired patterned glass; DIN EN 1096-1 for coated glass; DIN 18008-1:2010-12 8 DIN EN 1279 1 for insulating glass units; DIN EN 1748-1-1 for borosilicate glass; DIN EN 1863-
31、1 for heat strengthened soda lime silicate glass; DIN EN 12150-1 for thermally toughened soda lime silicate safety glass; DIN EN 13024-1 for thermally toughened borosilicate safety glass; DIN EN 14179-1 for heat soaked thermally toughened soda lime silicate safety glass; DIN EN ISO 12543-2 for lamin
32、ated safety glass; DIN EN ISO 12543-3 for laminated glass. The exact scope of application of the products is specified in the subsequent parts of this standard. 5.1.2 Material properties For the purposes of calculations performed within the framework of this standards series, the material properties
33、 stated in Table 2 shall be used for glass. Table 2 Material properties for different types of glass Type of glass Youngs modulus EGN/mm2Poissons ratio G Coefficient of thermal expansion T106/K Soda lime silicate glass 70 000 0,23 9,0 Borosilicate glass 60 000 0,20 6,0 5.1.3 Strength properties and
34、fracture pattern This standards series is based on the assumption that by complying with the relevant provisions for the product properties the minimum characteristic tensile bending strength (5 % quantile with a confidence level of 95 %) and the typical fracture pattern can be ensured for panes of
35、sizes used in buildings. 5.1.4 Edge damage Thermally toughened glass shall be checked for edge damage. Panes exhibiting edge damage penetrating into the glass volume by more than 15 % of the pane thickness shall not be installed. 5.2 Interlayers in contact with the glass It shall be ensured that all
36、 materials used are durably resistant to the actions to be taken into consideration (e.g. frost, temperature variations, UV radiation, suitable detergents and cleaning methods, contact materials), based on the assumption of professional maintenance and care. DIN 18008-1:2010-12 9 6 Actions 6.1 Exter
37、nal loads The characteristic action values to be used (selfweight, wind, snow, earthquake loads, etc.) and, if applicable, ice and climatic loads shall be taken from the relevant standards. 6.2 Insulating glass units 6.2.1 Pressure differences For verifications of insulating glass units in accordanc
38、e with DIN EN 1279-1, the effect of pressure differences between the cavity and the surrounding atmosphere shall be taken into consideration. Based on the conditions present during the sealing of the cavities, the pressure differences are a consequence of temperature changes of the filling gas and c
39、hanges in the pressure of the surrounding atmosphere. The changes in atmospheric pressure are a result of meteorological conditions and differences in the altitude at which the insulating glass units are manufactured and installed. 6.2.2 Combinations of actions Extreme pressure differences between t
40、he surrounding atmosphere and the cavity occur for the condition “winter” (with low temperatures and high-pressure conditions) and “summer” (with high temperatures and low-pressure conditions). In addition to the values for the temperature differences T and the changes in the atmospheric pressure pm
41、et, Table 3 contains information on the differences in altitude H to be applied to conditions covering normal cases. If the differences in the altitude exceed those assumed in Table 3, the actual value of the difference in site altitude shall be taken into consideration. If the actual differences in
42、 altitude are lower than those given in Table 3, the latter may be used.

43、n in Table 3 applies to insulating glass units having a total energy absorption of less than 30 % under normal conditions. For special conditions (e.g. internal solar protection device, unheated building) the values given in Table 4 shall be added or deducted. DIN 18008-1:2010-12 10 Table 4 Consider

46、1.2 When determining stresses and deformations, linear-elastic material behaviour shall be assumed for glass. 7.1.3 Favourable effects which are geometrically nonlinear (e.g. membrane effect in the calculation of plates) may be taken into account; unfavourable effects which are geometrically nonline
47、ar are required to be taken into account. 7.1.4 The calculation of the stresses shall be performed such that local stress concentrations (e.g. at drill holes and re-entrant corners) are taken into account with sufficient accuracy. 7.1.5 Effects due to the supporting structure (e.g. imperfections or
48、deformations) which result in stress increases that cannot be neglected shall be considered when performing the verifications. 7.1.6 For the glass thicknesses, the nominal values given in the relevant product standards shall be used. 7.2 Shear interaction 7.2.1 When determining stresses and deformations for laminated glass and laminated safety glass, favourable shear interaction between the individua
