摘要：Under the action of a strong earthquake, pier aqueduct structure is prone to injuries in the pier damage, making the whole structural seismic performance significantly reduced. Based on the concrete plastic damage constitutive model, a large gravity pier aqueduct structure is analyzed in the law of dynamic response under the action of earthquake. Compared with linear structure, the aseismic characteristics of the gravity pier aqueduct structure are studied. Research shows that: when considering material nonlinearity damage, pier department is bigger than the displacement of structure linear analysis. when considering the nonlinear damage, structure stiffness have significantly been lower, entered the stage of damage, making the whole structural seismic performance weaken.
