查询词典 concrete

No matter axial pressing or small eccentricity pressing of CFSTRC, it can be concluded such conclusions as following.(1)Compared with normal concrete filled steel tube, the CFSTRC has better ductibility and limited load-carrying capacity. The outer reinforced concrete offers much help to yield load and limited load.
