(CONT.)
Depending on the size and configuration of each DLO, the glass setting
blocks must be placed to give the best support of the glass without adding
dead load weight to deflect the horizontal. Figure 56 below shows typical
1/4 point and 1/8 point setting block locations. Contact EFCO Structural
Engineering for blocking requirements other than 1/4 and 1/8 points.
STEP 2) SETTING BLOCK LOCATIONS
Setting block locations should be determined by following the Dead Load
Charts shown in figures 57 and 58 below. These charts are for general
reference only and refer to laminated glass constructed from (2) 1/4" glass
panes and laminate material. If the glass size you require falls outside the
parameters of these charts or if your glass is not constructed from (2) 1/4"
panes of glass and laminate material, please contact EFCO Structural
Engineering.
