(2572) Trial load twist method (for gravity dams)
It is based on the assumption that the water load is divided between a structural system made up of vertical and horizontal elements with each system occupying the entire volume of the dam. For ungrouted joints there are two systems, the cantilever structure and the twisted structure. The grouted joints have three systems, the cantilever structure, the twisted structure and the beam structure. The division of load must be such that it causes equal deflections of each structure in all directions.
