| Abstract: | This paper gives a detailed introduction of the concept of loading features of steel-concrete girder at negative moment area. The definition of equivalent section and width is introduced and the formula of tensile area height and negative moment are derived. The bearing capacity resisting negative moment of composite beam is analyzed and summaries. |
