Due to moment resisting connections are made in both directions in steel frames, so beam-to-column web connections are generally as flange connection. The construction and performance under load of web connections are different from flange connections, and there are more difficulties for theory analysis and design. Studies on mechanism of beam-to-column web connections under cyclical load are not only significant to the theoretical research, but also important in practice.
