“…When the finite element method was used, the size of wharf model could not be taken to be infinite, only when the model try to get a large size model, but if the size was too large, it would greatly increase the computational workload, so the structure of the pier was simplified to improve efficiency in the process of finite element analysis if the results of the wharf strength were not affected [5]. C30 concrete was constructed the wharf, SOLID65 unit was used to simulate the caisson structure; the caissons structure were 200mm thin concrete, each small box size of caissons was 4500mm × 3600mm, which filled with stone, SOLID65 simulate unit was used in the ANSYS; the steel bridge was connected together by 10 beams of HEB200 [6]. In order to improve computational efficiency, the steel bridge was simplified shell element of SHELL63, which real constant value was assigned to the thickness of the flanged beam, the material of flanged beam was Q345.…”
