RESEARCH ON CCRST COLUMNS USED IN SEISMIC REGIONS
Concrete columns reinforced with concrete filled steel tube (CCRST) is a kind of steel-concrete composite column, which consists of an ordinary reinforced-concrete column with a steel tube designed to be put in the core additionally. Owing to the steel tube, the column is effective in improvement of the ductility, as well as in decrease of the column section size due to the enhancement of the bearing capacity. It is used quite extensively in high buildings in recent years in seismic regions in China. In this paper, a review of the practice application and research work carried out on the CCRST columns is given. The review lays emphasis on the experimental study work on its composite action under axial load, its seismic performance under cyclical lateral load, and a kind of unique RC beam-CCRST column joint.
