Abstract:Based on a study object of a double-column pier elevated station, it is found that the anti-overturning ratio coefficient in the Y direction of structure is smaller than that in the X direction through the reaction spectrum analysis. The seismic performance in the Y direction of station structure is analyzed by Pushover method. The results show that the structure of this station meets the related requirements of structural elastoplasticity. The super-strength coefficient in the Y direction of structure is greater than 2. The structure first produces the plastic hinge at the end of the second-layer column, and the production time of plastic hinge of the first-layer double column lags relatively. The analytical method based on Pushover can reflect the elastoplastic performance of the structure, which provides a basis for the design.
