Overview of Test Methods of Seismic Dynamic Behavior of Jumbo Container Cranes

文中对目前集装箱起重机结构地震试验研究的现状进行了系统地介绍,并总结出其发展趋势:(1)地震模拟振动台的大型化和多台化以及振动激励输入的多元化,以进行大比例模型试验,考虑地震的多向性和随机性;(2)提高试验模型相似性和复杂工况模拟度,以满足实验数据的精确性;(3)采用子结构试验配合整体结构试验,以分析结构的非线性性能并进行破坏性试验;(4)合理的支撑形式与接触状态模拟,以实现地震载荷的真实传递.

This paper introduces the current seismic test methods of container crane structures, and points out its developing tendency, including： （1） large-scale shaking table and multiple shaking ta- ble, diversity of vibration excitation, for large scale model test while considering diversity and ran-domness of earthquake; （2） Improving test model similarity degree , in order to meet the precision of the experimental data; （3） Adopting substructure test with whole structure test, in order to analyze nonlinear properties state simulation, in of structures and conduct destructive test; （4）Rational the support and the contact order to transmit the real seismic load.
