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.　©　2021　Elsevier　Ltd
