Due to the constraint of concrete slab to the beam top flange, the stability of steel-conerete posite beam is diferent from free steel beams. The method adopted in the Code for design of steel structures GB50017-2003 considers instability by restricting the slenderness ratio about the beam wcak axis which takes no consideration for the effct of concrete siab.Therefore, It can not be adopted in the stability analysis of steel-concrete posite beams. In addition,local stability in the negative moment zone should be considered. In the Shenzhen North Railway Station project, GB50017-2003 and Eurocode 4 are adopted to analyze the flexural capacity and stability of steel-concrete posite beams. Apart from that, elastic buckling analysis was performed with finite element program SAP2000 to account for the instability problems mentioned earlier. This analysis ensured the structure security.
