【Abstract】 The design of the new Jiangbei International Airport Building of Chongqing used some giant cast steel spares. we use the FEM software to set up a mode, in order to analysis the main and secondary truss of the new airport building, and also simulate the stress condition of the cast steel nodes, which working with defects, in the paper. At the final part of the paper, the evaluation on the safety bearing capacity of node is concluded positively.更多还原
