of ½ in. (13 mm). The geometric parameters describing the configuration of the extended end-plate
connection are shown in Figure 3-15. The definition of the geometric parameters used in Figure 3-15 and
the corresponding geometric parameter of each variable are tabulated in Table 3-3.

A W16x67 hot-rolled beam with length of 70 in. (180 cm) was connected to a W14x159 column with
length of 80 in. (200 cm). Two 10.2 in. (260 mm) L6x6x¾ hot-rolled angles were used to connect the
beam to the column. As shown, one leg of angle is connected to the beam flange by two rows of bolts,
and the other leg is connected to the column flange by one row of bolts. The geometric parameters
