*SHEAR RETENTION
18.12 *SHEAR RETENTION: Define the reduction of the shear modulus associated with
crack surfaces in a *CONCRETE model as a function of the tensile strain across the
crack.
This option is used to give a multiplying factor, , that defines the modulus for shea ring of cracks as a
fraction of the elastic shear modulus of the uncracked concrete. If this option is used, it should follow
the *CONCRETE option. The *SHEAR RETENTIO N option can also be used in conjunction with the
*FAILURE RATIOSoption.

Optional parameter:
DEPENDENCIES
Set this parameter equal to the number of field variable depende ncies included in the definition
of shear retention behavior, inaddition to temperature. If this parameter is omitted, it is assumed
that the shear retention behavior depends only on temperature. See “Specifying field variable
dependence” in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis User’s
Manual, for more information.
Data lines to define the shear retention behavior:
First line:
1. . The default is 1 .0.
2. . The default is a very large number (full she ar retention).
3. Not used.
4. Not used.
5. Temperature.
6. Firstfield variable.
