Simplified Computational Method for Seismic Response of LRB-isolated Aqueduct

YE Kun1,FU Rong2,LI Li1 (1.School of Civil Engineering and Mechanics,Huazhong University of Science an d Technology, 2.Division of Urban Construction Engineering of Wenhua College of Huazhong Unive rsity of Science and Technology,Wuhan 430074,China)  
In order to simplify the computational methods for seismic response of LRB-isol ated aqueduct structure,different computational methods are compared in the cou rse of conducting seismic response analysis of one large LRB-isolated aqueduct d esigned according to Intensity 7.These methods consist of 2DOF combined with bi linear model,1DOF combined with bilinear model,improved 1DOF combined bilinear model and finite model.Effect of damping and stiffness of piers on the numeric al results are investigated.It is shown that the mothod of improved 1DOF combin ed bilinear model is the easiest and can meet the accuracy of engineering demand.
