Advantages of Buttressed dams. Advantages of Buttressed dams. solid gravity dams resist the force acting against them primarily by weight alone. Strength of masonry is critical only when the height is great, and then only over limited areas. In massive arch dams, the strength of the masonry is more fully developed. However, not all dam sites are suitable for massive arches.
Frequently, a reduction in cost with no surfice in safety can be effected by a dam of structural form. Because of the more efficient development of latent strength, masonry quantities are reduced. More intricate form work and the need for reinforcement increase units costs, but under favorable conditions an appreciable net saving in total cost may be achieved. This is particularly true in locations where the cost of procuring or transporting the cement required for a more massive structure is prohibitive, or where other construction materials are scarce.
