| Abstract: | For present time, B type girder is a widely applied removable small span steel girder. Via Midas/Civil, a 24m B type girder finite-element model is introduced in this thesis. Based on this model, self weight calculation, middle-live load function, further displacement & stress under load combination, girder body's natural vibration characteristic are described respectively. Through these comparison and analysis, a conclusion can be obtained that the displacement and stress of B type bridge girder meets the ... |
