Abstract

Abstract: The bending characteristics of angle steel bracket arms for tunnel cable supports exhibit considerable complexity, and improper design and selection can pose serious safety risks to the operation of cable lines. Take a 110 kV cable tunnel project in Jining area as a background, a three-dimensional refined model of the cable angle steel bracket is established using the finite element software ABAQUS, which is utilized to investigate the failure modes and load-displacement curves of cantilever angle steel components subjected to concentrated load. Meanwhile, a series of parameter influence analyses are completed, and design recommendations are provided.

Key words: cable supports, cantilever angle steel components, flexural stability bearing capacity
