The report primarily discusses results obtained from the conducted experiments and includes computed data from the Kingston computer program. The value of the plastic moment capacity of each experiment was obtained; Obtained value was used to find the yield strength of the structures and compare them to typical values for mild steel. The important data is summarized in a table; followed by a list of important formulae. All individual results are listed in the appendix at the end.

1. Development of A Plastic Hinge A plastic hinge is formed when the yielding has spread throughout the entire cross section of a member, reducing rotational stiffness to zero. (Todd, 2000) When a member reaches it’s maximum yield stress, it does not result in failure. The member continues to take additional load and as the load continues to increase, more
