Cyclic loading test for partial frames with new column support system for multi-story steel moment resisting structures to perform beam yielding mechanism

In our previous papers, the new column support system is suggested, and it is shown that the columns base for the steel moment resisting fbmes never yield during large earthquake by the dynamic analyses. In this paper, the cyclic loading tests are performed for the partial steel fbmes with the embedded column base or our proposal new column support system. The columns for the proposal support system are shown to keep elastic by the large plastic range of the frames such as the angle of 0.05, even though the columns for the embedded column base become as much plastic as the beams.
