Bed Joint Installation
5.0 DESIGN EXAMPLE — FULLY GROUTED CMU CONSTRUCTION
The following design example , based on the masonry anchor design provisions of ICC-ES AC58 , is intended for illustration purposes only .
PARAMETERS
Figure 5 — Examples of Nearest Adjacent Head Joint for Bed Joint Installation
Anchors A and B in Figure 5 represent single anchor installations . They illustrate which head joint would be considered the nearest adjacent head joint edge ( c hj
) for the respective anchor .
Anchors C and D in Figure 5 represent a two-anchor configuration . They illustrate which head joint would be considered the nearest adjacent head joint edge when installed in the bed joint between two head joints .
Anchors E and F in Figure 5 represent a two-anchor configuration . They illustrate which head joint would be considered the nearest adjacent head joint edge when installed in the bed joint with a head joint between them .
Anchors G and H in Figure 5 represent a two-anchor configuration . They illustrate which head joints would be considered the nearest adjacent head joint edges when installed in different horizontally adjacent CMU blocks .
The same process utilized for calculating tension breakout cones in face of CMU installations can be used for anchors in bed joint installations .
