Description
<p> Damage to light poles mounted on viaducts under Level 2 earthquake must be avoided because it could create traffic disruption that would impede the post-earthquake emergency function of transportation networks. In this study, the plastic deformability and damage morphology of light poles were investigated and confirmed in the full-scale static loading tests using actual light pole structure. Based on results of the loading tests, the limit state, and the allowable deformation of light poles were determined to ensure its function in the case of emergency on transportation roads. Excessive seismic-induced vibrations are commonly observed on light poles mounted on viaducts due to response amplification of the viaducts. Accordingly, a practical seismic design method is proposed to verify that the seismic-induced displacement does not exceed the limit state 2 using dynamic analysis of the viaduct and the light pole. Furthermore, as a case study, earthquake resistance of the light pole on an existing viaduct was examined.</p>
