MASONRY Q & A :: What is the masonry standard or preferred for a brick veneer bearing on a steel lintel? 4" or 8" bearing?
Lintel bearing for veneer is covered in TMS 402 Chapter 12. Specifically 18.104.22.168.2 states "not less than 4 inches". Your architect/engineer should size it for you. Keep in mind that if it is anchored to the backup you must install and expansion joint at one end minimum. If the opening is very wide you may need an exp jt at both ends. I hope this helps. If not, call me. Thanks for allowing your MAF/MCAA to help.
