【Abstract】 In this paper, formulas for computing natural frequencies and modes of CFRDs are derived based on the additional mass and stiffness method according to shear wedge beam theory. The influences of concrete\|face to natural frequencies and modes are discussed. Furthermore, the seismic responses of CFRDs are calculated by using the mode\|superposition scheme. The calculated results are compared with the responses of rock dams.更多还原
