Abstract：
To validate the rationality of finite element model, Steel-concrete composite beam has been compared by theoretical calculation and finite element calculation .With the same loads, performance of simple composite beams,steel truss beam and SCCTG have been anａlysis by finite element software ANSYS. The results of the data analysis revealed mid-span deflection of SCCTG is smallest, and the total steel consumption can be reduced 22.6%. It shows the SCCTG has the obvious advantage on force performance and project cost.
