Passive Energy-Dissipation Control for Aqueduct Structural under Earthquake Based on SIMULINK

摘要

The passive control for aqueduct under earthquake exaction is a complex process, especially when the control devices have multi-variety optimization problems, it is difficult to solve complex model by using conventional optimal methods. According to such problem, based on the MATLAB/SIMULINK platform, the finite element model of isolated aqueduct is established, a dynamic program is designed, and the lead rubber bearing (LRB) is used to control the seismic response. The result indicates the solution method based on the SIMULINK block is simple, precise, and facile, with intuitional and believable results. Setting LRB can efficiently reduce the input energy of earthquake. The results from the present study may serve as a reference base for seismic analysis of large-scale aqueducts.
