Theoretical Research On Bearing Capacity Of Cold-Formed Steel-Concrete Composite Beams

As a kind of transversal composite element, Cold-Formed Steel-Concrete Composite Beams has the higher load bearing capacity,the better rigidity and the bigger deformation. Because of the great advantages of Cold-Formed steel-concrete composite beams,it comes to be widely considered by more and more structural engineers. Based on comprehensive collection of existing research documents in and beyond our country,the performance of Cold-Formed Steel-Concrete Composite Beams with hat section under static and monotonic loads,such as flexural capacity,deflection.Studies show that these composite beams have high flexural capacity and large defommation.Nonlinear finite model of Cold-Formed Steel-ConcreteComposite Beams with hat section are simulated by ANSYS in this paper.The ersults of finite element received throuch calculation analysis and test research are similar.It proves that the finite element analysis of Cold-Formed Steel-ConcreteComposite Beams is correct.Moreover,the influence,such as the strength of concrete,distance of anti-shear connections and thickness of concrete slab,are analyzed.The results show some parameters have influence on flexural capacity . With it,I hope to take the theory to a high layer.
