This paper presents a study on the compressive behavior of a novel type of highly deformable hybrid FRP tubular columns. The columns consist of an FRP tube filled with large-size recycled concrete lumps (RCLs) as aggregates and flowable grout as the binding material, and are thus termed FRP-RCL-Grout (F-R-G) columns. The use of large-size RCLs (e.g., up to 63 mm RCLs for 200 mm circular columns) leads to a relatively high recycling ratio and facilitates the manufacturing process. The flowable grout can be easily poured/pumped into the FRP tube, leading to ease of construction, while the FRP tube acts as an effective lateral confining device. The experimental part of the study involved compression tests on F-R-G columns and similar columns for comparison, with the main test variables being the FRP tube thickness, the size of the RCLs, the compressive strength of the concrete for producing RCLs and the WP ratio of the grout. The test results showed that F-R-G columns possess excellent st ....
Abstract This paper presents a study on circular fibre-reinforced polymer (FRP)-concrete-steel hybrid multitube concrete columns (MTCCs), which consists of an outer FRP tube, a number of inner small steel tubes to form a “steel wall” and concrete filled in the remaining spaces. The advantages of MTCCs include excellent axial load and deformation capacities, ease of construction, elimination/mitigation of difficulties in transporting and installing large steel tubes, and possibility of optimising the arrangement of the small steel tubes to improve structural performance. A total of 7 pairs of MTCCs, 4 pairs of concrete-filled FRP tubes (CFFTs), 4 pairs of concrete-filled steel walls (CFSWs) and 3 pairs of concrete-filled steel tubes (CFSTs) were tested in the present study, with the investigated parameters covering the thickness of FRP tube, the number and type of steel inner tubes, the type of concrete and status of the steel inner tubes. The test results lead to an in-dep ....
