*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 shearing 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 RETENTION option can also be used in conjunction with the
*FAILURE RATIOS option.

Optional parameter:

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition
of shear retention behavior, in addition 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 shear retention).

3. Not used.

4. Not used.

5. Temperature.

6. First field variable.
