This research investigates the development of a finite strip computer program for the analysis of laminated anisotropic folded plate roof structures and cylindrical shells. The finite strip method appears to have a great potential in predicting the static response of the anisotropic structures under consideration since the computer storage requirements for the finite strip method is relatively small. In addition, the incorporation of the anisotropy and coupling effects in the finite strip formulation are essential for accuracy purposes. The main contribution of this research is to extend the application of the finite strip method to predict the actual behaviour of some types of laminated structural systems considered herein. Numerical results are presented to illustrate the potential of the method for predicting the structural response of laminated shell roof structures. The time and effort required to obtain a solution on a personal computer of relatively limited size is minimal in comparison to the other methods. The results of the treated examples indicated that the effect of the coupling stiffness in laminated unbalanced sections may be significant and that the influence of this coupling decreases rapidly with the increase ln the number of layers while it increases in sections of layers made of strong materials. Using the proposed model, the convergence of the results for stresses and displacements can be obtained with a reasonable limited number of strips and terms of the basic displacement functions.
