英文摘要： Earthquakes pose a significant threat to the safe use of large habor machinery, and the increasing size of container cranes has resulted in vulnerability to seismic loads which has not previously been recognized. To explore the failure mode and mechanism of large container crane under earthquake loads and to improve the seismic performance of the crane structures is one of the problems much needed to sloved and paid high attation in the field of safe use and design for large seaport machinery. Base on frictional contanct theory, large deformation theory, dynamic time-history quantitative calculation and the statistics analysis performed on nonlinear finite element mode, and vibration earthquake simulation experiment, this project is planned to perform researches on the seismic performance evaluation and dynamic behavior of jumbo container crane under earthquake loads by combination the theory analysis, nonlinear finite element modeling and experimental study method.Research contents mainly includes establishing nonlinear dynamics detailed mode, the key parameters identification and experimental investigation dynamic behaviors of jumbo container crane under seismic exitations and the seismic performance evaluation of crane based on seismic structural fragility. The research is aimed to provide the basic analysi
