Considering of the condition that the steel reinforced concrete beam is mainly used to bear the vertical load and preserve the robustness of integrated structure, this paper takes the flexural rigidity of beam subjected to short-term load effect as the damage characterization of SRC beam. According to the related theoretical analysis and experimental research, the damage sensitivity of various design parameters which contain the sectional height, the strength of concrete and steel ratio are analyzed, and the influence laws of main design parameters impacted on damage evolution of SRC beam are revealed. The research shows that sectional height is proved to be the most sensitive factor in the damage of SRC beam and the steel ratio takes the second place, and then the strength of concrete is the most insensitive to the damage of SRC beam. The research achievements will provide theory and date support for establishing the storey damage model of SRC frame structure under seismic excitation.
