ABSTRACT
This chapter considers a specific type of masonry structure known as Guastavino or thin-tile domes. Guastavino domes are concentric thin-tile domes constructed without formwork. In order to design the appropriate scaled model, the geometric and material property scaling factors for the structure need to be considered. The development of scaling factors or the ability to apply the results of a scaled model to full sized structures relies on the concept of similitude. The scaling law is derived by applying scaling factors to all dimensions, material properties and frequencies and then substituting those scaling factors into the results of the test model. To develop strictly geometric scaling factors, in this parametric study the material properties and boundary conditions are kept as constants. The scaling factor for density is developed using the same method as modulus of elasticity. The scaling factors can also be used to design small scale physical models for laboratory testing.
