Abstract:Cast steel joints are used in the steel grid tube structural system and the connection of complex joints of China Comic & Animation Museum. Finite element method analysis and full-scale experiment were used to analyze the mechanical properties of cast steel joints. The finite element method analysis revealed the stress distribution law of the joint through the numerical analysis method. Under the action of 1.3 times design load, the full-scale experimental results were in good agreement with the finite element method results. According to the finite element method analysis and experimental results, the joint design was optimized. Under the action of design loads, the cast steel joint was in elastic working state. The ultimate bearing capacity of the joint was more than 3 times of the design load.
Keywords:China Comic & Animation Museum; steel grid tube structure; cast steel joint; finite element method analysis; experimental study; ultimate bearing capacity
