Load and Resistance Factor Design ( LRFD )

THE FUTURE OF POST-INSTALLED ANCHOR DESIGN INTO MASONRY

Load and Resistance Factor Design ( LRFD )

The International Code Council ( ICC ) acceptance criteria which defines the testing method for post-installed mechanical and adhesive anchors into masonry has recently undergone an upgrade , enabling engineers to capitalize on keybenefits in their designs .

The revised acceptance criteria results in a change in design method , allowing engineers to design LRFD for their post-installed anchoring connections to masonry . This new design method will be based on ACI 318 / CSA A23 anchorage provisions .
NEW LRFD DESIGN METHOD AVAILABLE
