Advanced Glass Designer

The edition of ASTM E1300 the check follows. It sets the thicknesses offered, the largest design load within its scope (210 psf in 09a, 315 psf in 12a, 16 and 24) and the deflection appendix.

Short is a 3 second load, such as a wind gust. Long is a 30 day load, such as snow. The duration sets the glass type factor of E1300 Table 1. The durations marked † (10 s to beyond 1 year) use the load duration factors of E1300 Appendix X4 (Appendix X6 in E1300 09a) on the 3 second load resistance; they are not offered for laminated glass.

Four sides uses the E1300 four sided charts. Three sides with one free edge uses the E1300 three sided charts, which cover 2.5 to 22 mm glass and aspect ratios of 0.5 to 5. Two opposite edges and one edge use the E1300 charts for those supports, which cover 6 to 22 mm glass.

The nominal designation of E1300 Table 4. The E1300 chart is read for this designation; the other methods use its Table 4 minimum thickness unless you enter a thickness.

Leave it empty to use the Table 4 minimum thickness. An entered thickness is used by the appendix method and the plate solver; the E1300 chart is still read for the nominal designation.

The angle of the glass from vertical: 0 is vertical, 90 is horizontal. Glass more than 15 degrees from vertical is sloped. The weight of the glass normal to the glass is added to the load at every angle above 0. Leave it empty for vertical glass.
