The paper takes the metal structure of 600 t derrick crane in certain company as the study object, and con-ducts simulation analysis on it with Ansys to get the stress distribution of the structure under 4 typical working conditions. The electrical measuring method is used to perform site stress test on the structure.The static strain indicator is used to get the static stress under testing conditions.By comparing the simulation results and test results, the paper shows that the structure strength is consistent with the design requirement.Simulation analysis on the structural strength and site test meth-od provides theoretic basis for security evaluation on the crane structure.
