| Abstract: | Problems of nonlinear free and forced vibrations of rectangular double-deck orthogonal and ortho-laid reticulated shallow shells on unmovable clamped condition are studied by means of the nonlinear bending theory of double-deck orthogonal and ortho-laid reticulated shallow shells and the method of double Fourier series. Using perturbation method, the relationships between nonlinear frequency and amplitude are obtained. [ |
