Extreme Loading of Wharf Crane Girders
Wharf crane girders are designed for loads that are likely to occur. Although rare, extreme loads that are not considered in design do occur. Extreme loads result from severe wind, earthquakes, missing piling, crane collisions, crane collapse, and other abnormal conditions. Extreme loads significantly exceeding the conventionally computed wharf crane girder strength often do not cause significant damage. This paper presents what happens when wharf crane girders are subjected to extreme loads near or beyond their calculated design capacity, the performance that can reasonably be expected when extreme loads occur, and which extreme loads should be considered in the design of wharf crane girders. Topics presented in this paper include: (1) sources and descriptions of extreme loads; (2) case studies of extreme loading events and the resulting wharf crane girder performance; (3) explanations of wharf crane girder performance and implications for girder design and capacity evaluation; and (4) a discussion of, and recommendations for, reasonable extreme load design criteria.
