Abstract |
This study was carried out to analyze and compare the stability of a 50ton container crane according to various wind load design codes. The wind load was evaluated according to ‘The Specification of Port Facilities and Equipments / Specification for the design of crane structures (KS A 1627)’ and ‘Load Criteria of Building Structures’ enacted by the ministry of construction & transportation And the uplift forces of a container crane under this wind load were estimated by analyzing reaction forces at each supporting point and compared each other.
From this study, we noticed that the design wind velocity criteria need to be defined specifically when the wind load is evaluated to design a container crane. And we verified the necessity of the estimation of the uplift forces at each supporting point to analyze a structural stability of a container crane and the maximum compressive force in order to consider the stability of the ground foundation of the berth. |
