CLASSIFICATION OF DAMS: Dams are classified on several aspects, some of the important aspects are as follow: 1) Based on Hydraulic Design: Over flow dams (e.g. concrete dams) Non over flow dams (e.g. embankment dams) 2) Based on Structural Design: Gravity dams Arch dams Buttress dams 3) Based on Usage of Dam: Storage dams Diversion dams. Gravity dams are constructed of vertical blocks of concrete with flexible seals in the joints between the blocks. Buttress: A buttress dam is a specific type of gravity dam in which the large mass of concrete is reduced, and the forces are diverted to the dam foundation through vertical or sloping buttresses. Arch: Concrete arch dams are.
Pocket Safety Guide for Dams and Impoundments. October The Federal Emergency Management Agency (FEMA) has developed. this information for the guidance of its employees, its contractors, and. its cooperating Federal and State agencies and is not responsible for the interpretation or use of this information by anyone except. its own File Size: 8MB. Gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape, mass and strength of the concrete. The purposes of dam construction may include navigation, flood damage reduction, hydroelectric power generation, fish and wildlife enhancement, water quality, water supply, and by: 2.

Fitting the dam in the valley The criteria for fitting the dam are similar to those of a vibrated concrete gravity dam. Design Procedure of Concrete Gravity Dams Another criteria which is important for arch dams is the shape of the canyon, if it is symmetrical an arch dam is often very suitable. Dr. Bakenaz.

DESIGN CRITERIA FOR CONCRETE ARCH AND GRAVITY DAMS In addition to the safety factors specified, addi- tional allowances for safety tend to enter into a design as a consequence of overly conservative treatment of successive uncertainties encountered in sequential design operations.

Hammond. Engineering and Design GRAVITY DAM DESIGN 1. Purpose. The purpose of this manual is to provide technical criteria and guidance for the planning and design of concrete gravity dams for civil works projects.
Applicability. This manual applies to all HQUSACE elements, major subordinate commands. Case 2 - Normal loading condition; water surface at normal reservoir level plus an ice load of 5, pounds per linear foot, where ice load is applicable.
Dams located in more northerly climates, may require a greater ice load. Case 3 - Design loading condition; water surface at spillway design.

provided within the dam, th e drain effectiveness and uplif t assumptions should follow the guidance provided in paragraph 3- below, and should be veri fied by instrumentation. Rock Foundations In the case of gravity Dams on rock founda tions, a failure plane shall be assumed between the dam and the Size: 1MB.
This part of water load depends primarily upon the amount of curvature. The balance of the water load is transferred to the foundation by cantilever action. The thrust developed by the water load carried by arch action essentially requires strong side walls of the canyon to resist the arch forces.
concrete structures; however, thin arch dams are exceptions. Massive structures, such as gravity dams, resist loads primarily by their shape and mass, and only secondarily by their strength.
Of more importance are durability and properties connected with temperature behavior and. The concrete in the dam is homogeneous in all parts of the structure.
Assumptions of maximum earthquake accelerations equal to one tenth of gravity are adequate for the design of important masonry dams without including additional allowances for resonance effects.
In monolithic curved gravity and arch dams, some proportions of the loads. Guidelines on Design Criteria for Concrete Gravity Dams (September ) Within about ten years of the edition of the ANCOLD Guidelines on Design Criteria for Concrete Gravity Dams being published the Limit State design approach it proposed fell out of favour with Australian dam engineers.
The ANCOLD Executive recognised this situation and resolved that the Guidelines be revised to reflect the preferred design approach amongst Australian dam engineers. A concise review of the principles of the project design of dams is presented.
This involves feasibility studies, preliminary design, selection of type of dam, and final detailed design. The procedure differs according to the choice of dam, such as gravity, fill, or other concrete or composite dam. Examples are given of large dams across the.

Key concepts of arch dams Concrete arch dams are complex three-dimensional shell structures that File Size: KB. Uplift- is not usually of importance in thin arch dams, but in thick arch dams provision is made for internal drainage, as for gravity dams.
If the design assumes that the concrete will crack if tensions exceed say MPa, then it is consistent to assume that full hydrostatic pressure can act in such cracks. Design of Arch Dams: Design Manual for Concrete Arch Dams.

- GHD Global. CONCRETE AND MASONRY DAMS 6 Concrete And Masonry Dams GRAVITY DAMS Gravity dams (see Figure ) are the most common of the concrete and masonry types and the simplest type to design and build.
A gravity dam depends on its weight to withstand the forces imposed on it.Till the middle of the s, the designed codes for concrete arch dam and gravity dam regulated by the US Bureau of Reclamation suggested that the full-graded aggregates should be adopted in the behavior testing for the strength or elastic modulus of dam concrete, and the smallest size for the specimen should be larger than three times of the.Arch-gravity dams are massive dams of concrete that resist the thrust of water by their weight using the force of gravity and the arch action.
An arch-gravity dam incorporates the arch's curved design that is so effective in supporting the water in narrow, rocky locations where the gorge's sides are of hard rock and the water is forced into a narrow channel.
