6.0 PROFIS Engineering Tips
Hilti’ s PROFIS Engineering Suite software is a user-friendly, cloud-based application that helps make designing post-installed anchor connections easier. Anchor design in masonry base materials has been available in the software for the past few years. The software has been updated with the new design provisions from ICC-ES AC01 and AC58 to help users transition to these new industry standards. With that in mind, this guide will provide tips and tricks for modeling certain masonry conditions within the software. The following PROFIS models are intended for illustration purposes only.

For CMU construction, the software defaults to assuming closedended units with hollow head joints. For designing with openended units with solid head joints, there is an option available to select that will allow the software to analyze the head joint as completely filled with grout or mortar. The option is located in the geometry parameters in the base material design tab. Choosing this option will toggle the influence of hollow head joints on CMU design as discussed in Section 4.0.
When selecting“ Grout-filled CMU” as a base material, the software defaults to assuming fully grouted CMU construction. For designing anchors located in the grouted cells of a partially grouted CMU construction, there is an indirect method to influence the software to analyze partially grouted CMU construction. For designing anchors located in the ungrouted cells or when the location of the grouted cells is unknown, select“ Hollow CMU” as the base material.
For partially grouted CMU construction with the grouted cells filled and reinforced vertically( i. e., grouted cells on different courses), reduce the edge distances in the x-direction to the appropriate nearest adjacent hollow head joint as well as either the nearest ungrouted cell( for single anchor configurations) or the opposite nearest adjacent head joint( for multi-anchor configurations installed in different vertically adjacent CMU blocks). See Figure 6 and Figure 7. The software will analyze the influence areas accordingly if the correct application edge distances in the y-direction are modeled in the software.
For partially grouted CMU construction with the grouted cells filled and reinforced horizontally( i. e., grouted cells on the same course), reduce the edge distances in the y-direction to only model the course with grouted cells. See Figure 8. The software will treat the top edge of the course and bottom edge of the course as the edge distances, which will align with treating the nearest adjacent ungrouted cells as edges. The software will analyze the influence areas accordingly if the correct application edge distances in the x-direction are modeled in the software.
