Stability Analysis of"Y"Shaped Steel Column Based on ABAQUS
The stability of"Y"shaped steel column used in Guangzhou-Shenzhen-Hong Kong high-speed Railway Humen Station renovation and extension project is analyzed.By using ABAQUS software,the stability of"Y"shaped steel column is numerically simulated.The section properties,stress distribution,buckling modes and instability mechanism of"Y"shaped steel column are analyzed.Through the simulation results,it can be seen that the weak point of the structure appears at the joint of the steel box girder and the left and right steel inclined columns,and the strengthening measures should be taken during design and construction.The force transmission path of the triangular structure is very reasonable,and it can maintain a good overall shape in normal use and to a certain extent under heavy loading,so as to ensure the safety of use.
