These codes were already implemented in CYPECAD and Metal 3D as of previous versions. Now with the 2014.g version, CYPECAD offers two options for users to indicate the value of the Fundamental period of the structure (used to calculate the base shear):

• Based on the code
  Only option in previous program versions for these codes.
• Specified by the user
  Implemented in the 2014.g version for these codes, although this option was already available, as of previous versions, for other seismic codes: CFE 2008 (Mexico), NTC 2004 (Mexico), NC 46:1999 (Cuba) and NSR-10 (Colombia).
