Outline of Final Research Achievements

For beam-to-column connection of the steel building, the gradual increase amplitude cyclic loading experiment which assumed loading speed (period 1Hz and 0.01Hz) were carried out. This experiment is fundamental researches for the performance evaluation technique construction that can evaluate the influence that the fracture property of the member end and the yield mechanism of the frame give to the ultimate state of the building. The conclusions obtained from this experiment are (1) The difference in loading speed produced differences of some behavior.(2) In the dynamic loading, beam-to-column connection fracture occur in comparison with static loading earlier, and plastic deformation capacity was inferior. For sliding in the high-strength bolt friction joint, the possibility that it hastened the crack spread started from the welding defect is thought about.
