2. In the first load step, apply a force or displacement to node K. In this case, the load is applied as a force.
   The force “locks” on the second load step, allowing you to add additional loads. The effect of the initial
   load is preserved as a displacement after it is locked. This is shown in the following example.
   sload,1,PL01,tiny,forc,100,1,2


3. Apply other external loads as required using the SLOAD command.

The following example help you to understand how the pretension procedure works.
