Research Abstract

The objective of this study is to formulate the load-displacement relationship which can evaluate the local buckling limit, shrinkage limit in case of CFT columns, crack occurrence limit and initial yield limit in case of SRC columns and beams.
As to the concrete filled columns, Tsuda investigated relation between experienced lateral drift angle and residual one of concrete filled steel tubular columns. As the results, 1) residual drift angle becomes large as the axial load ratio of the column becomes large, 2)the effect of width-thickness ratio and diameter-thickness ratio on the residual drift angle is not apparent, comparing with the axial load ratio, 3) in specimens with high axial load ratio, the residual drift angle becomes large after the column attained the shrinkage limit.
Moreover, accumulated plastic angles are calculated using previously performed test. As the criterion, shrinkage limit, local bucking limit, strength assurance limit are selected, and effect of width-thickness ratio, diameter-thickness ratio and axial load ratio are examined.
Fujinaga and Tsuda investigated the relations between cyclic and monotonic behavior on CFT beam-columns by using the previously performed experiment and numeric analysis. While in the small deflection stage, monotonic behavior correspond to envelop curve of cyclic behavior, in the large deflection stage, monotonic behavior correspond to accumulated curve of cyclic one.
As to SRC beam, Sakai and Lee performed experimental test, selecting the encased steel ratio and existence of slab as the test parameters. Sakai examined the load deflection relationship.
