   :noindex:

   This command is used to construct a uniaxial time-dependent concrete material object with linear behavior in compression, nonlinear behavior in tension (REF: Tamai et al., 1988) and creep and shrinkage according to fib Model Code 2010.

.. note::

   #. Compressive concrete parameters should be input as negative values (if input as positive, they will be converted to negative internally).
   #. Shrinkage concrete parameters should be input as negative values (if input as positive, they will be converted to negative internally).
