ABSTRACT
In order to clarify the force transmission characteristics of the plate in the anchorage zone of the main cable of the long-span self-anchored suspension bridge, the solid and shell finite element model of the local stress analysis of the main cable anchorage were established based on the 428 m three-tower four-span self-anchored suspension bridge of Fenghuang Road across the Yellow River in Jinan City of China. The stress characteristics of the main plate such as cast steel anchor under the most unfavorable load conditions were analyzed, and the force transmission mechanism and distribution model of the axial force of the main cable in the main beam were revealed. The results show that the axial force of the main cable on both sides of the cast steel anchor is more than 80 %, and the concrete bridge deck and concrete in the compression zone are the main bearing member due to the large relative rigidity.
