Effect of Different Types of Middle Columns on the Seismic Performance of Single-Story Subway Station Structure by Sheng Li, Haiyang Zhuang, Wei Wang, Liguo Jin, Zhengfang Dong

“…The results show that, compared with the rectangular columns, the circular columns with the equal moment of inertia suffer less damage in the earthquake and have better seismic performance. The prefabricated CFST columns can effectively ensure that the middle columns of the station structure are not severely damaged and can be replaced quickly after the earthquake, which improves the overall seismic performance of the subway station structure and the rapid recovery ability of the structural function after the earthquake.…”

Seismic Analysis of Coupled High-Speed Train-Bridge with the Isolation of Friction Pendulum Bearing by Xinmin Hong, Wenhua Guo, Zihao Wang

“…Taking the rail irregularities as system’s self-excitation with the seismic as external excitation, the equation of motion of the train-bridge coupled system under earthquake is built up. A five-span simple-supported railway bridge is taken as an example, and the computer simulation method is used to establish the dynamic model of the train-bridge system with the isolation of FPB under earthquake. …”

Seismic Response Reduction of Megaframe with Vibration Control Substructure by Jun-Qi Huang, Xun Chong, Qing Jiang, Xian-Guo Ye, Han-Qin Wang

“…The results indicated that (1) the proposed MFVCS could provide a considerable seismic response reduction under frequent earthquake and showed a strong robustness; (2) the optimized values of the frequency ratio (ratio of tuning frequency to the megaframe’s natural frequency) and damping scale factor (ratio between the investigated damping and a standard value) were 0.96 and 1.0, respectively; and (3) the seismic response reduction of the MFVCS under rare earthquake was lower than that under frequent earthquake.…”
