| Prefabricated reinforce concrete arch bridge has many advantage of manufacture technology maturation、easy to construct short durationgood appearance spanning capacity, so it widely used by highway bridges.the node which used as a force transmission component, is easy to suffer seismic damage.The global seismic disasters happened frequently in recent years.This paper absorbs the previous research of the theory and proposes the research topic in the basic of the previous research.This paper is involved in research on influence of seismic resistance behavior reinforcement methods for joint of prefabricated reinforce concrete arch bridge and it’s adjacent region in high seismic intensity zone.Here is a simulating analysis on the earthquake resistant behavior of the prefabricated reinforce concrete arch bridge using the common limited member commercial software Midas civil, to show the behavior that some design scheme perform under the strong earthquake. And compare the efficiency of different method, for reference to designers.This paper is looking at Prefabricated reinforce concrete arch bridge in practical engineering, the basic content of this paper are as follows:(1) First, this paper discusses the present situation and future trend of Seismic Design of Bridge Joints.Then using jinshajiang bridge as an example, to analyze the mechanical characters of existed connection node.(2) Utilized general FEM software to establish mechanical model and solve, time history analysis with the model of connection node and it’s adjacent region have been done.(3) To perform the time history analysis on the whole bridge with different connection node.Compare their results and summarize regulations.(4) To compare the efficiency of the connection node before and after Strengthen on Earthquake Resisting.This paper focus on close to the actual engineering project, fully analyzed the feasibility and applicability of some concise and effective schemes, for designers to reference and modify. |
