Abstract
With the development of the control research, intelligent control has become one of the most popular research topics worldwide. The traditional method of Numerical simulation on control theories are realized by the programs in MATLAB, which is based on numbers of assumptions and simplification. However, it is difficult to ensure that the seismic response of the structure is always in linear elastic state during the process of hazard evolution under strong earthquake so that certain errors during such simulation are inevitable. In order to solve this problem, a numerical method of the realization of semi-active control in commercial finite element software ABAQUS is proposed in this paper. One of the main advantages of this method is that the structural plastic response can be taken into account. In this paper, the seismic response of a bridge with three-span continuous girder is numerically studied, and the semi-active control is successfully realized in ABAQUS. The proposed method can be used to carry out the refined simulation of the seismic response of the structures with semi-active control set. The highlight of this paper is to provide an effective approach for the research of intelligent control.
