Numerical Analysis of Y-type Cast Steel Joint for Guangzhou New Railway Station
As for a new type of joint of steel structures, cast steel joints are used for large and complicated steel structures. Combined with the analysis of Y-type cast steel joints for the New Railway Station of Guangzhou, the performance of this type cast steel is discussed. With the help of ANSYS software, the distribution of the stress, the process of plasticity spreading and the failure mechanism of Y-type cast steel joints are analyzed. In order to further investigate the stress concentration, a parametric study of Y-type cast steel joint was conducted considering the influence of factors, such as corner fillet radius of different branch members, branch member thickness, and stiffener thickness. The results show that the Ytype cast steel joint of Guangzhou New Railway Station is safe. And the corner fillet and stiffer can reduce the stress concentration of joints. But the thickness of branch members has small relation with stress concentration.
