Lots　of　bulidings　had　collapsed　in　Wenchuan　big　earthquake　in　2008,　one　important　reason　is　that　the　structure　design　has　been　launched　only　in　X　or　Y　axis　of　the　building　respectively,　which　means　the　oblique　direction　compression-bending　characteristic　has　not　been　fully　considered　in　the　actual　structure　design　process.　In　addition,　the　moment　bearing　strength　in　oblique　direction　is　smaller　than　the　moment　strength　about　the　principle　axis　of　the　column,　so　the　research　on　bending　strength　calculation　of　biaxial/oblique　compression-bending　RC　column　is　important　to　improve　the　aseismic　safty　of　the　buildings　under　actual　earthquake　effects.　In　this　paper　research　achievements　about　bearing　capacity　calculation　of　column　under　oblique　compression-bending　action　are　summarized　and　analyzed.　At　last　the　advice　for　actual　application　has　also　been　given.
