摘要
Abstract
Quayside container crane is the major equipment used for lifting containers at modern ports. Since most of the ports locate in the coastal seismic zone, friction dampers are employed to ensure the safety and reliability of the cranes under seismic loads. In this paper, based on energy design method, an anti-seismic device with the friction dampers was designed for a quayside container crane. To validate its efficiency of energy consumption, a scaled model was designed, tested and simulated. After measuring the friction coefficient of the damper in the quayside container crane prototype, the elastoplastic time-history response of the friction damper was analyzed under the accidental-grade seismic intensity. The results show that crane with the friction damper installed has batter anti-seismic performance than that without the friction damper. It is suggested that the cranes with the friction dampers installed can reduce the seismic damage and retain full or partial capacities of loading and unloading.关键词
