About this detail

Typical reinforcement details for concrete masonry wall openings and end conditions. Head bars and U-ties are specified at wall openings with sizing based on opening width, ranging from two number five bars for openings up to six feet wide up to four number seven bars for openings up to sixteen feet eight inches wide. Jamb bars and end of wall bars are provided in single or double curtain configurations with lap splices per schedule. A minimum one inch or bar diameter clearance is maintained, and open end block is required typically. The typical elevation shows the spatial relationship between head bars, jamb bars, the slab on grade, and the foundation.
