Study on strength of reinforced concrete filled circular steel tubular columns

다국어 초록 (Multilingual Abstract)

Concrete filed steel tubular columns (CFT) are widely used in civil engineering works,especially in large scale of works because of high strength, deformation, toughness and so on. On thein Hansin-Awaji earthquake of Japan in 1995, reinforced concrete piers were wrapped with steel plate.Then, a new kind of structure appeared, that is, reinforced concrete filed steel tubular column (RCFT). Inthis paper, compresion test and bending-shearing test on RCFT are carried out. The main parameters of(4) arrangement of reinforcing bars. According to the experimental results, the effect of parameters onmechanical characteristics of RCFT is analyzed clearly. At the same time, strength evaluation formula forRCFT column is proposed and tested by experimental results and existed recommendations (AIJ 197).proposed evaluation formula can evaluate the strength of RCFT column properly.
