Investigation of falling behavior of communication cables from bundling hangers Part 2

Estimation of sectional force on hanger joints due to static wind loads

Abstract

For installation of overhead communication cables, multiple communication cables are often bundled using a bundling hanger, which is supported by a suspension wire. To estimate the sectional force acting on the joints of the bundling hanger, steady aerodynamic force measurement tests were carried out for each component, and static wind response analysis, in which the contact of each component was considered, was carried out for a full span model. Although the sectional force acting on the hanger changes depending on the boundary condition of the communication cable, the static wind load is not enough to cause the failure of the joints.
