A　dent　is　a　typical　defect　found　in　oil　and　gas　pipelines　and　poses　a　significant　threat　to　their　safety　and　integrity.　In　this　study,　the　buckling　behavior　and　limit　strain　capacity　of　pipelines　with　kinked　dents　under　bending　moment　loads　were　investigated.　First,　four-point　bending　tests　of　full-scale　pipelines　with　kinked　dents　were　conducted　in　a　laboratory,　and　the　critical　buckling　load　and　strain　response　of　the　pipelines　during　buckling　failure　were　tested.　The　test　results　revealed　that　the　existence　of　kinked　dents,　specifically　those　with　large　depths,　could　weaken　the　bending　resistance　of　the　pipelines.　During　the　buckling　process　of　the　pipeline,　a　considerable　compressive　strain　was　generated　at　the　bottom　center　of　the　dent,　which　was　considerably　higher　than　the　strain　value　at　the　corresponding　position　of　the　intact　pipeline.　However,　the　strain　at　both　axial　sides　of　the　dent　gradually　changed　from　compressive　strain　at　the　initial　bending　stage　to　tensile　strain　after　buckling　failure.　Then,　nonlinear　finite　element　(FE)　models　of　buckling　failure　for　pipelines　with　kinked　dents　under　bending　moment　loads　were　developed,　and　the　reliability　of　the　FE　models　was　verified　through　comparison　with　the　test　results.　In　addition,　a　parametric　sensitivity　study　was　conducted　to　determine　the　effect　of　parameters,　such　as　dent　depth,　dent　angle,　diameter-to-thickness　ratio　of　the　pipe,　and　yield　ratio　of　the　pipe　steel,　on　the　compressive　strain　capacity　of　the　pipeline.　Finally,　based　on　a　large　number　of　FE　simulation　results,　a　model　for　predicting　the　buckling　compressive　strain　capacity　of　pipelines　with　kinked　dents　was　developed,　which　can　be　used　for　evaluating　buckling　instability　failure　of　pipelines　with　kinked　dents　subjected　to　bending　moment　loads.
