Analysis on Seismic Vulnerability of Elevated Stations Based on Capacity Spectrum
The analysis of seismic vulnerability is a method for assessing seismic damage.The seismic performance of elevated station structures is studied by using the Pushover capacity spectral analysis method.The emergence mechanisms of inter-story displacement angle and plastic hinge are studied to obtain the vulnerability curve and vulnerability matrix.The results show that the elevated station structure example suffers mainly minor damage or a small probability of moderate damageunder all levels of seismic action,and that the inter-story displacement angles meet the performance design requirements.The method used is simple and feasible,and the results are available for reference.
