Element Method

Through the ANSYS finite element method, the seismic performance of frame columns reinforced with wing walls has been analyzed, indicating that the wing wall reinforcement can effectively improve the lateral stiffness and remarkably increase the bearing capacity of columns. With the wing wall reinforcement, the envelop area of the column’s hysteresis curve increases, and the bearing capacity improves, however, the shrinking phenomena of the curve suggests that the ductility of the section reduces. When the centerline of the additional wing wall coincides with that of the original column, the hysteresis curve inclines to be full, thus advising overlapping the centerline of the wing wall with that of the original column.

In this paper the effect of nonlinear behaviour of concrete is investigated on seismic performance of a double curvature concrete dam. The Morrow Point concrete dam has been selected as the case study and dam-reservoir-foundation interaction considered in the model. Finite element method has been used for modelling and analysis of case study by applying the El Centro earthquake components considering nonlinear behaviour of concrete. The obtained results of nonlinear dynamic analysis illustrate the increasing of displacement of dam crest along the river and decreasing of maximum principle stresses in critical points. The results demonstrate the importance of consideration of nonlinear behaviour of material in seismic performance of arch dams to achieve the optimal design of models.
