Abstract


The port terminal occupies an important position in the national economic and social development . Port interrupt will cause huge economic losses and social impacts . Previous earthquake damage : pile wharf structure vulnerable to earthquake damage . Experts in earthquake damage studies , soil liquefaction , inappropriate Ferry structural performance and node performance is the main reason for the destruction of the wharf structure . Existing pile wharf , using the finite element dynamic analysis of the pier overall structure , explore reduce the vertical piles node stiffness reasonable . The tenon joint connection damping energy principle proposed an energy consumption gap vertical piles node . Monotonic loading and low cyclic load analysis , to investigate the the node seismic performance and failure mechanism , to seek to improve the pile piers seismic performance of the node . The research results are expected in this article have important reference value for the project of the National Natural Science Foundation of China , has an important significance for improving the seismic capacity of the domestic and international terminal structure to reduce earthquake risk . The research of this paper is as follows : 1. The pier overall dynamic response of the structure under horizontal seismic finite element analysis, analysis of the different vertical piles node of the pier structure and draw reasonable reduce the vertical piles node stiffness . With the overall power analysis results , the the tenon joint connection damping energy principle , proposed an energy consumption gap straight pile node design . . For seamless vertical piles nodes and gap nodes monotonic loading vertical piles , compare each force performance . Gap nodes using the the different piles core reinforcement ratio low cycle repeated loading comparative analysis of the energy consumption characteristics of gap nodes . The paper based on the existing analysis measures for further improvement of the nodes , and provide a reference for further study .
