Increasing Crane Girder Capacity Using the Strut-and-Tie Method

摘要

Over recent decades, vessel size and the weight of the heaviest marine containers have increased, resulting in increased crane reactions to the wharves. The larger ships have greater drafts, which require deeper berths. So many of the Port of Oakland’s existing wharves cannot carry the heavier crane loads and continue to meet the original design criteria. rnThis paper presents the strut-and-tie method of analysis and new criteria for determining the acceptable crane loads on the existing wharves. For most wharves, the new method of analysis increases the acceptable load.
