A Study on Behavior and Fatigue of Bolted Ring Flange Joint in Tubular Tower Supporting Cable Car by using FEM Analysis
ABSTRACT： For line towers supporting cables of cable car or ski gondola, circular tube sections and bolted ring flange joints are widely used. Since these line towers are undergoing fluctuating load due to successive unbalanced load coming through cross-beam holding cables, bolted ring flange joint including bolts and welds should be checked for fatigue load. Behavior on fatigue in these joints are different depend on variety in shape, flange-plate thickness, pretention level in bolt and others. Six different FE-models are presented and the results are discussed in regard to the connection design and the fatigue assesment for bolt and welded joint.
