Dynamic response analysis on caisson wharf structure under earthquake
The caisson wharf's seismic response is an essential issue in the design and construction. The finite element method is used in numerical simulation. The complex internal components of the caisson structure are usually simplified when modeling, and connection between steel and concrete which affect the results are ignored. Based on the project of Putian port, constraint equation method is used in the numerical model, dynamic response of caisson wharf under earthquake is studied and results of static analysis and dynamic time history analysis are obtained. It shows that the proposed numerical modal is more realistic and can obtain more reasonable results. Under seismic action, displacement and stress increase obviously at the beginning of earthquake, and decrease with time until a trend of stability. As the shape mutation, the stress concentration phenomenon occurred at the caisson front toe and back toe, and toes need to be strengthened during design and construction. The results can provide a reference for the seismic design of caisson wharf.
