| Abstract: | Small scale model test method is used to study the dynamic properties and response of
arch dams with transverse joints. In order to obtain a full understanding of the effects of joints on
the behaviour of arch dams, three different types of arch dams-fully jointed, partially jointed and
jointless arch dams are tested. Linear and nonlinear FEM computations are carried out, and similar
results are obtained. With the test and computation results, the analysis on the joint failure
mechanism of arch dams under strong seismic excitation is provided, and some constructive
suggestions are presented. |
