v6.03.143 SSNP143 — Validation of keying/sawing for the law of joint of stud joints of dams

Summary:

Two industrial procedures on dams are tested: claving and sawing.

Clavage is like injecting concrete under pressure between the studs of a dam. It is an intermediate stage in the construction of an arch dam, it serves to reinforce its watertightness after the phase of constructing vertical posts. Sawing is a similar procedure in which the dam is sawn in order to release stresses. This can happen before or after the water is put into the water. This test makes it possible to validate the two procedures by doing the keying/sawing between the two regular studs, which are either embedded in the ground and subjected to the gravitational force (models A, B, E, F, G, H), or compressed on the sides (models C and D). The procedure is defined via a keyword PRES_CLAVAGE and SCIAGE in DEFI_MATERIAU for the material JOINT_MECA_RUPT/FROT. The corresponding laws have the same names. We test the behavior of two-dimensional and three-dimensional joints, corresponding to the models: PLAN_JOINT and 3D_ JOINT.

Modeling A: 2D industrial keyboard; law JOINT_MECA_RUPT

B modeling: 3D industrial claving; law JOINT_MECA_RUPT

C modeling: 2D theoretical sawing; laws JOINT_MECA_RUPT/FROT

3D modeling: 3D theoretical sawing; laws JOINT_MECA_RUPT/FROT

E modeling: 2D industrial sawing; law JOINT_MECA_RUPT

F modeling: 3D industrial sawing; law JOINT_MECA_RUPT

G modeling: 2D industrial sawing; law JOINT_MECA_FROT

H modeling: 3D industrial sawing; law JOINT_MECA_FROT

For claving, the thickness profile of the joints after claving is compared with the results provided by another calculation code (SOURCE_EXTERNE GEFDYN). For sawing, a comparison is made with a theoretical estimate (modeling C and D). In addition, tests of NON_REGRESSION of the values of the thickness of the joint, as well as of the corresponding forces, are carried out.
