Analysis of axial force variations and seismic performance of subway ...
2024年11月1日 · For subway stations, due to the disharmony between the deformation of the side wall and the central column, the central column often has insufficient lateral deformation capacity and more serious damage, which also shows that the central column is a vulnerable component and the main cause of structural damage [[17], [18], [19], [20]]. Thus ...
Research on Seismic Performance of a Two-Story, Two-Span
2024年5月10日 · The behavior of center columns in shallow-buried underground subway station structures resembles that of high-rise buildings. In both cases, these columns experience significant vertical loads during earthquake events and are susceptible to brittle failure due to inadequate deformation capacity.

Abstract: The center columns of shallow buried underground subway station structures are similar to columns in 1st floor of high-rise structures in that both are subject to large vertical pressures under earthquake action and are prone to brittle failure with insufficient deformation capacity. In this paper, the design concept of split column ...
Cyclic Behavior of Central Columns in Subway Stations Subjected …
2024年6月19日 · The failure mode of concrete columns in subway stations during seismic events can be affected by the dynamic fluctuation of the axial forces. This study conducted quasi-static tests with bidirectional loading on three scaled rectangular columns to investigate the influence of highly variable axial compression ratio (ACR).
Influence of ground motion duration on inelastic seismic response …
2024年7月1日 · For subway stations, the center columns are generally arranged in the longitudinal direction at a fixed distance. For the Daikai subway station, it is about 3.5 m. The analysis results in Section 6 demonstrate that the duration effect will exacerbate the inelastic deformation and damage of the center column due to the lower bending stiffness.
The pushover analysis of the working conditions of the center column ...
The behavior of center columns in shallow-buried underground subway station structures resembles that of high-rise buildings.
Static analysis of the hysteretic performance of the central columns …
2023年12月1日 · Through the analysis of the dynamic elastoplastic time history of central columns in subway stations under the influence of ten seismic waves, it has been observed that an increase in seismic fortification intensity accelerates both the frequency and amplitude changes of the vertical axial force in these columns.
Abstract: The behavior of center columns in shallow-buried underground subway station structures resembles that of high-rise buildings. In both cases, these columns experience significant...
