ON THE EFFECTS OF CIRCULAR BOLT PATTERNS ON THE ...

column flange by one row of ¾ in. diameter high strength A-325 bolts. The geometric parameters
describing the configuration of the welded/bolted double web angle connections are shown in
Figure 3-18. The definition of the geometric parameters used in this figure and the corresponding
geometric values of each parameter are tabulated in Table 3-6.

3.3.5 Flush End-Plate Connection
A W18x46 hot-rolled beam with length of 70 in. (180 cm) was connected to a W14x159 column with
length of 80 in. (200 cm). The size of the end-pate was 6 x 18 in 2 (15.2 x 45.7 cm 2 ) with the thickness of
3/8 in. (9.5 mm). The geometric parameters describing the configuration of the flush end-plate
