3. DESCRIPTION OF PROBLEM OR FUNCTION

SAFE-CREEP performs a
viscoelastic analysis of plane or axisymmetric composite concrete
structures with age- and temperature-dependent creep data.

[ top ]

4. METHOD OF SOLUTION

The  program uses  the finite-element  method
which reduces the  problem to the solution of a  system of coupled
integral equations.   The method of  solution is iterative  on the
space variable and  utilizes the trapezoidal rule  integration for
the time variable.
