Design And FEA Of Batter Pile Joint On Pile-Wharf Structures

The harbor holds the important status in the state .The harbor severance can create the huge economic loss and the society affects.In 1995 the Kobe earthquake, Kobe port created the direct economic loss surpassed 11 billion US dollars.Under the earthquake, the pile wharf is very easy to destroy. Experts which shakes harms the research to believe that: soil liquefies, unsuitable wharf structure performance and joint performance is the main reason that creates the wharf disarrangement of the structure..Against the existence question of pile wharf, the article has carried on the dynamic analysis with the finite element theory to the wharf construction. According to the ananlysed result, combine the use of steel pipe pile, a kind of batter pile joint has designed, and carry on monotone load and low-cycle test simulation to it, discuss it's stress performance, by improves the seismic performance of pile wharf. This article anticipated research results have the important reference value regarding the country natural sciences fund project research, regarding enhances the domestic and foreign wharves structure the earthquake resistance ability, reduces the earthquake risk to have the vital significance.The concrete work of herein is as follows:1. Using ANSYS analyze the reaction of pile-wharf with knuckle in straight pile and usually pile-wharf in horizontal earthquake. Comparing the first period, the quay horizontal displacements, the inertial force and the internal force, discusses the seismic performance of pile-wharf with knuckle in straight pile2. Considering the use of steel pipe pile, combine the dynamic analysis result, a kind of cap of batter piles is designed. To discusses the influence of stirrup to joint stress performance, adopt finite element carry on monotone load and low-cycle test simulation to it.
