Research on Safety Evaluation of Quayside Container Crane Metal Structure Based on 04-FCE

Abstract

In order to ensure the safety of quayside container crane in service and improve the port safety management level, from the engineering practice, according to the composition of the quayside container crane metal structure of six parts: the front girders, the rear girders, the beams, the trapezoidal frame, the tie rods, the columns, the factors that potentially have influence on the safety of the metal structure are researched, and the safety evaluation index system is built. The dimensionless algorithm of evaluation index is optimized emphatically. For the first time, the “0-4” evaluation method is used to calculate the weight value in the evaluation algorithm, and the 04-FCE evaluation method which combine the “0-4” scoring method and fuzzy comprehensive evaluation is proposed. The safety level and evaluation conclusion of the quayside container crane metal structure are determined, the suggestions for reducing the risk are given, and the rationality analysis is carried out through an example at last.
