Suspenders are main force-transmission components of half-through and through arch bridge, It is crucial for safety of bridges to its reliability and durability. Safety of the arch bridge will change when a suspender sudden failure, and affect the safety of the structure. Selecting a through arch bridge in Yunnan Province as the research object, it based on the three-dimensional finite element, this paper studied the dynamic response of arch bridge suspenders sudden failure on the failure-safety theory.

Definition Of

Based on ANSYS for modal analysis of bridges, the basic steps includes: building up the FEM model, applying the load and solving the model, expanding the mode, observing the results and so on. Taking the Friendship Avenue Arch Bridge as an example, the building procedures of FEM model were described from the definition of member section, element selection, and the determination of relevant attributes. At last, the dynamic characteristics of the bridge were analyzed based on ANSYS. The results showed that the first 10th order vibration frequencies of the Friendship Avenue Arch Bridge ranged from 1.3Hz to 3.1Hz, and the more order modes should be considered when calculated the dynamic response based on the mode superposition method.

The Impact

As a new type structure, the dynamic behavior of the irregular concrete filled steel tube arch bridge under moving vehicles was rarely studied. In this paper, taking the bridge crossing Yitong river in Changchun of China as an example, the dynamic response of the bridge is investigated by the self-compiling vehicle-bridge coupled vibration analysis program. The surface roughness and vehicle speed are considered in the analysis. The results show that impact factors of the bridge increase as surface roughness deteriorated; the impact factor varies obviously for the different component; the tension impact factor of the short suspender is larger than that of long ones; damping ratio of structure has little effect on the impact factors. The research conclusions can be referred in the design and assessment for the similar bridges.

As one of the most important components of CFST arch bridges, the cross beams should affect the bridges’ dynamic performance and response magnificently by means of affecting these three factors mentioned above. Based on the Maocaojie Bridge, its FEM models of half-through CFST arch bridges with different settings of cross beams are built. The different seismic responses of six operating conditions are calculated with three dimensional earthquake waves input. The internal force and displacement envelope diagrams of arch ribs are extracted and analyzed in situations of in-plane moment, out-plane moment, vertical displacement and transverse displacement. It can conclude that the joint section between arch rib and bridge deck should be designed carefully because of its large displacement and internal force, and the cross beams should be optimized to safety the arch bridge dynamic response considering lateral rigidity. The conclusions may be useful to the seismic design and strengthening treatment of CFST arch bridges. To strengthen the joint section between arch rib and bridge deck or optimize the setting of cross beams will increase the ductility of half-through CFST arch bridge and decrease the damages caused by large earthquake.

Explosion Accidents

In order to reduce loss of terrorist attacks or accidental explosion accidents to traffic facilities of the state and society, antiknock safety of long-span bridge needs to be further studied. A deck arch bridge calculation model of fluid-structure interaction was established, and explicit dynamic analysis was presented to study the dynamic response of long-span arch bridge under blast loading, and the explosion effect to the overall structure of the bridge was analysed. The results show that the area around explosion center, has local large deformation and heavy damage degree, while a little far region has low deformation and damage degree; When explosives is located on the deck, the damage of blast-impact load on the main arch ring can be neglected, which is advantageous to the late bridge repair work. The results of this article can be provided as important theoretical reference to antiknock and explosion-proof of bridges in the future work.
