3.3 Beam-Column Connection
For further verification of the numerical results obtained from the finite element models on the
extended end-plate connections with circular and square bolt patterns presented in Chapter-5, it was
important to validate the numerical results against the results obtained from full-scale connection
experimental testing. To achieve this goal, the experimental results of five bolted beam-column
connections with various connection details were selected and the corresponding finite element models
were developed. These results were used to validate the numerical results in Chapter-4.
In this chapter, a summary of the experimental work of a) extended end-plate connection, b) top-
and-seat angle connection, c) welded/bolted double web angle, d) bolded/bolted double web angle
connections, and e) flush end-plate connections conducted by Abolmaali et al. [64][65] is presented. The
results of these studies are used in Chapter-4 to validate the results obtained from the numerical
analysis.

3.3.1 Extended End-Plate Connection
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). The size of the end-pate was 10½ x 22½ in. 2 (27 x 57 cm 2 ) with the thickness
