Preliminary Study on Built-Up Back-To-Back Cold-Formed Steel Stub Column Filled with Washed Bottom Ash Concrete

Cold-formed steel (CFS) is formed by using steel sheets over rolling, pressing, and bending processes at ambient temperature. Due to its benefits, CFS in a range of cross-sections and shapes is used as a structural and non-structural element. However, CFS used as columns and beams tends to fail due...

Cold-formed steel (CFS) is formed by using steel sheets over rolling, pressing, and bending processes at ambient temperature. Due to its benefits, CFS in a range of cross-sections and shapes is used as a structural and non-structural element. However, CFS used as columns and beams tends to fail due to local buckling, distortional buckling and global buckling when subjected to load. Besides, CFS needs to be modified to ensure that the section is stable and able to save from structure integrity issues. The study’s main aim is to evaluate the mechanical behaviour of built-up back-to-back CFS columns and filled with special concrete. A built-up section of CFS is created by connecting two CFS channel sections in a back-to-back configuration and filling it with washed bottom ash (WBA) concrete. WBA is classified as a waste material collected from landfill areas at coal electrical power plants and had gone through some washing processes. Coal after being used is dumped in landfill areas and created a lot of environmental problems. WBA replaced the natural sand in the concrete with a full amount. The column is tested and compared with the built-up back-to-back CFS without the concrete and with normal concrete. From the compression strength result, the built-up back-to-back CFS column with WBA concrete decreased by around 25.53% when compared with the built-up back-to-back CFS column with normal concrete. Finally, the column is appropriate for the column with less load capacity that can be utilised in the construction or infrastructure. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
