[关键词] 吊车梁 疲劳 校算 加固A method of the fatigue life analysis for the steel crane girder of a steelworkshop is put forward. According to actual condition, the strengthening scheme of the crane girder has been brought forward. The scheme is easy to construct, and saves investment. It also gives no disturbances to the adjacent structures during construction.
Keywords: steel crane girder; fatigue; checkout; strengthening参 考 文 献
