The upper and lower structural steel columns are connected with finished square cut ends joined by a complete joint penetration groove weld. An erection plate is centered across the joint to align the sections during erection. The weld configurations are specified as complete joint penetration demand critical welds with optional choices noted for the contractor. The splice is detailed four feet above the finished floor level. Notes mandate adherence to AISC specifications regarding weld access holes and transition details for unequal member thickness and width.
NOTES: 1. WHERE STEEL BACKING IS USED IN CJP BEAM FLANGE GROOVE WELDS, STEEL BACKING AND TABS SHALL BE REMOVED, EXCEPT THAT TOP FLANGE BACKING ATTACHED TO THE COLUMN BY A CONTINUOUS FILLET WELD ON THE EDGE BELOW THE CJP GROOVE WELD NEED NOT BE REMOVED. 2.
