Abstract:

This paper presented the experimental investigations and numerical analyses on the compressive behavior of pultruded concrete-filled GFRP tubular (CFGT) short columns after lateral impact. Taking the thickness of GFRP tube, concrete compressive strength, impact height, and impact location as influential factors, 117 CFGT short columns were tested under axial compression, including 108 specimens after lateral impact and 9 specimens without impact. Tear-up and Tear-up included local buckling were two main failure characteristics of specimens under axial compression. Test results indicated that the increase of thickness of GFRP tube remarkably enhanced the residual ultimate strength of specimens subjected to lateral impact. The impact height exerted negative effects on the residual ultimate strength and axial stiffness of the CFGT short columns. The residual ultimate strength of the specimens decreased significantly as the impact height increased, especially for the thin-walled specimens. However, the impact location only showed a limited influence on the residual ultimate strength of CFGT short columns. According to the experimental results and theoretical analyses, the design formulas were proposed to estimate the residual ultimate strength of CFGT short columns after lateral impact.
