Abstract: For a high-rise complex structure built at an earthquake zone, response characteristics to an earthquake action are always needed to be as an important index to evaluate its dynamical performances. This article carried out a three-dimensional dynamical response analyses of a large-scale complex sluice-dam structure by using the software of ANSYS under a strong earthquake excitation by nonlinear finite element method. Through the analyses of the time history response of the high-rise complex structure to the specified earthquake records, the seismic performances of the structure system under consideration of the rock foundation-sluice structure-reservoir water interaction were well evaluated.

Abstract: In this paper a sluice project is taken as an example. Dynamic finite element method is used to analyze dynamic response of sluice structure under the action of seismic acceleration (0.157g). The subspace iterative method is used in the modal analysis of the sluice structure after the finite element model is established, the natural vibration frequencies, and mode shapes are obtained. And then the response spectrum method is employed to implement dynamic response of the structures. The results show that the dynamic stress concentrations take place on some regions

Abstract: This paper takes a sluice reconstruction project as an example. The constraint internal force, the related axis force, bending moment, and shearing force at the corresponding section are solved according to the unit stress and internal force balance. Furthermore, technology of mesh auto-generation in cross-section is utilized to plot the internal force graph of the structure directly, which will provide reference for reinforcement design and make it more convenient.
