Seismic Response and Fragility Analysis of a Single-Pylon Cable-Stayed Bridge Considering the Construction Process

Xiangliang Tang, Pan Mao, Guanghui Liu, Haodong Xu et autres

The structural system, construction stage, and damper parameters have significant influences on the seismic performance of single-pylon cable-stayed bridges. To investigate the seismic responses of the bridge under various construction stages, nonlinear finite-element models were established in OpenSees for the pylon stage, …

Research on construction control of single-pylon steel-concrete composite girder cable-stayed bridge

Qiangqiang Yan, Lei Li, Guoxi Tang, Haiyang Yu et autres

This study investigates construction control strategies for a single-pylon cable-stayed bridge with a steel-concrete composite main girder and prestressed reinforced concrete side spans. A staged finite element model in Midas/Civil simulates the construction sequence, including deck crane effects, segmental erection, and stay-cable …

Seismic Performance of a Suspension Bridge Considering Saddle–Cable Slippage

Xiaoxian Liu, Xuejian Zhang, Xinchao Guang, Min He

In a suspension bridge, slippage may occur at the saddle–cable interface during an earthquake. A refined finite element model of the saddle–cable interface is proposed which considers the compressive force and friction force at the curved contact surface. To investigate the saddle–cable …

Seismic Performance of Steel-SMA Reinforced Columns: Numerical Investigation

Xiaoxian Liu, Xuejian Zhang, Jingfeng Wang, Nailiang Xiang et autres

The residual displacement of a bridge column governs its functionality after a severe earthquake. A box girder bridge was selected as a case study. Pushover analysis, quasi-static cyclic analysis, incremental dynamic analysis and fragility analysis were conducted to compare the seismic performance …

An Efficient Method for Predicting the Residual Displacement of UBPRC Columns Under Near-Fault Ground Motions

Jian Zhong, Yuanyuan Wei, Yahui Shao, Tao Yang et autres

As an effective measure to decrease the residual displacement under earthquakes, unbonded prestressed concrete (UBPRC) columns have been carefully investigated in previous research, while the influence of the complex characteristics of near-fault excitations on the residual displacement of UBPRC is less mentioned. …

Numerical modeling of rigid frame suspension composite bridge

Wu Chenfei, Wenrui Zhou, Xiaoxian Liu, Yin Yong-gao

Large span continuous rigid frame bridges often suffer continuous deflection of the middle span in the service. In this paper, the rigid frame-suspension composite bridge is proposed in which main cables and hangers are adopted to support part of the beam weight …
