Abstract | The structural performance of multi-celled GFRP hollow beams is highly affected by the local buckling failure. Therefore, this study introduces pultruded multi-celled GFRP beams filled with low strength concrete. The flexural behaviour of beams made up of 1, 2 and 3 pultruded GFRP square sections (125 mm x125 mm x 6.5mm) and filled with concrete having low compressive strength was investigated. The composite beams were subjected to four-point static bending test to determine the strength, stiffness and failure mechanisms. The results of the experimental investigations showed that the failure stress of 2 and 3 cells beams is 98% and 85% compared with single cell beam, respectively. However, the filling percentages are 50% and 33%, respectively. All the tested beams were failed due to compression failure of the GFRP profile. Furthermore, the effective stiffness of 2 and 3 cells is 95% and 96%, respectively compared with single cell section. |
