| Abstract: | In this paper, we use boundarg elemnt method, making the domain integral of inertial force to be the intgral at the boundary of the field, and have calculated the natute frequencies of gravity dam with an empty reservoir. The computational results are compared with the finite element solustions. The comparision indicates that the method presented in this paper is vilid. |
