Container Quay Crane Structural Response under Trolley Traveling

Structural response of quay crane should take more attention with the growth worldwide logistics demand and size. This paper analyzes mechanism metallic structure induced by trolley traveling. An on-site test has been conducted. The time domain girder acceleration signal shows that main influence traveling on is high-frequency impact passing through hinge point. spectrum frequency vertical vibration vibration. Single model theoretical derivation reveal displacement quasistatic. A refined numerical whole established. interaction between realized S-M contact method. calculated results are basically consistent measured signal. result indicates same information as such structural in-service affected in band. three directions 10 points show significant effect displacement. lateral eccentric loading condition girder. little dynamic structure. can be treated
