摘要
Steel moment resisting frame (SMRF) connections between vertical columns (14) and horizontal beams (19) are for both original and retrofit building construction. The SMRF connection is a column tree assembly (13) consisting of primary trunk assembly (17) engaging secondary branch assembly (18). Primary trunk assembly (17) has vertical parallel gusset plates (25, 26) secured to vertical column (14) with flanges (27) at each beam-to-column joint location, and base plates (28) at one end of the column and a splice (33) at the other end. Secondary branch assembly (18) is secured normal to primary trunk assembly (17) between parallel gusset plates (25, 26). Secondary branch assembly (18) includes stub beam section (30) fitted with shear transfer plates (32) secured to the web of stub beam section (30) and to parallel gusset plates (25, 26). Plate (28) is secured to each flange of the stub beam (30) and parallel gusset plates (25, 26) to bridge the gap (31). Vertical shear tab plate (32) is secured to the web of stub beam (30).
