摘要：
Steel-concrete composite beams have been widely used in the high-rise buildings and large span steel structure. Composite beams' effective flange width has been further investigated in domestic, as well as the force and deformation within elastic stage and plastic stage. In this paper, we give out the formula derivation of steel-concrete composite beams' stiffness amplified coefficient. Combined with a practical engineering, we analysis the impact of stiffness amplified coefficient on the whole structure by SAP2000 software and compare the results back and forth. In the end, we put forward some suggestions for construction engineers.
