Abstract:
To explore the effect of prestressing forces on the seismic behaviors of arch dams, a set of model tests on shaking table were carried out. The arch dam model was made with a configuration of three-centered circular, which simulated Shi Men Zi arch dam built in Sinkiang. With a shape steel bracket, which simulated rigid foundations, the prestressed model was tested to study the dynamic behaviors of arch dams with contraction joints. The test and calculation results show that with prestressing not only the opening of the contraction joints is distinctly reduced, but also the natural frequency of arch dam increases in some degree. Comparison of the tested and numerical results shows a good agreement and it suggests that the simple numerical model proposed in this paper is reasonable for the arch dams with prestressed cables/wires under dynamic loadings.
