| Research Abstract |
This research reveals the results of experimental studies concerning the moment carrying capacity of steel wide flange beams subjected to cyclic bending. Wide flange beam specimens were dynamically loaded in various loading sequences under the condition that local and lateral bucklings and connection fractures were effectively prevented. The major findings obtained from these tests are as follows: 1) the bending moment carried by beams increases during the initial three cycles under constant displacement amplitude, and subsequently reaches the upper limit. 2) the possible maximum moment capacities are obtained for both short and normal beams related to the maximum deformation amplitude of the beam member, and 3) flexural strength demands for beam-to-column connections for the ultimate seismic design of steel moment resisting frames can be evaluated taking into account deformation amplitude and the number of excursions during the earthquake response.
