- Abstract:
- Based on the theory of the elastic-plastic fiber-beam-column element,a two-dimensional numerical model of a steel-concrete hybrid wind turbine tower is established to study the tower's aseismic performance.The limit values of five damage states of the tower are determined according to the results from the pushover analysis,then the sectional curvature is used as the structural demand parameter,and IM1I&2E,which considers the higher order modes,is used as the composite ground motion intensity parameter.Twenty ground motion records are selected for the incremental dynamic analysis of the tower to establish the seismic vulnerability curves of the tower for the evaluation of the seismic performance of the tower.The results show that the hybrid tower model can meet the aseismic requirements for an Intensity Ⅶ(0.15 g)earthquake,and a special aseismic design should be taken into account when the tower is under the action of rare earthquakes(Intensity Ⅷ or over)or when the tower is located in the higher intensity areas.
