Abstract

In the project, experimental studies have been devoted to investigating the buckling behavior of timber Filled Circular hollow Steel Tube (CHST) stub columns strengthened by Carbon Fiber Reinforced Polymer (CFRP) laminates. The present Stub Columns were under pure axial Compression. Several tests were conducted on different specimens such as bare Circular Hollow Columns and Timber, Hollow columns wrapped with CFRP, Hollow Columns filled with timber, and CFRP wrapped tubes with timber infill specimen respectively and the impact of each material was studied on the structural behavior of these members under axial compression. The CFRP confined members preventing local outward buckling. At the time, the buckling was occurred inside of the specimen. The results indicated the application of CFRP sheets for strengthening steel short CHS columns. significantly increment on the load-bearing capacity and delaying local buckling were observed. Thus, the timber-filled specimens were found to significantly improve the strength by preventing local inward buckling. The practical benefits of composite timber-steel encased columns are also discussed, notably the potential to express the materially of wood and offer a market for low-grade timber with smaller cross-sections.
