(1 Faculty of Construction, Guangdong University of Technology, Guangzhou 510006,China; 2 School of Transportation, Fujian University of Technology, Fuzhou 350002, China)Abstract: Based on the experimental study of 12 axially loaded circular steel tube filled RPC slender columns and 4 axially loaded circular steel tube filled RPC columns, this paper collects the data about lateral deflection.longitudinal strain and ultimate bearing capacity, describes failure modes of axially loaded circular steel tube filled RPC slender columns, and analyze the characteristics of load deflection curves. Preliminary study of axially loaded circular steel tube filled RPC slender columns influenced by hoop coefficient and slenderness ratio is discussed.
