Suspender is an important component of through arch bridge which transfers loads from bridge deck to arch rib, and its mechanical property is closely related to the safety of whole bridge. When suspender is damaged, the change of its tension will lead to internal force redistributions of the arch bridge. In this thesis, taken Xinkai River Bridge of Harbin-Dalian high-speed railway as a case study, which is the first long-span steel-box stacked arch bridge for high-speed railway in China, a finite element model is established by using the MIDAS/Civil software. By analyzing the calculation results and comparing static performances under non-destructive conditions, the influence of damage of suspenders on steel-box stacked arch bridge is summarized, which can provide reference data for health evaluation of the bridge during service period.

In view of huge destructibility of the near-fault ground motions, structures with long natural vibration period are liable to fall into nonlinear reaction stage. Based on a full understanding of the near-fault seismic spectrum characteristics, the out-of-plane seismic response of a long span concrete-filled steel tube (CFST) arch bridge was studied in depth, and the research result could offer a reference for near-fault aseismic design.

Large-span V structure tied arch bridge structure system is complex. In order to make the actual state of the bridge into the ideal state of maximum close to the design, we must make real-time monitoring in the key parts of the structure, and adjust to the design of the data by analysis calculated, to ensure the safety and reliability of arch bridge in the course of construction and into stress after the completed bridge. Combined with the construction monitoring of the main Xinglong Bridge on Si River, this paper introduces the main bridge construction process measurement a preliminary study on the large span V configuration basket tied arch bridge construction monitoring technology. Based on the construction monitoring of Xinglong Bridge on Si River, this paper introduces the main contents and methods of monitoring point location, monitoring control of construction process, and discussed the construction monitoring technology of long-span X-style tied arch bridge V structure.
