Normas Técnicas Complementarias para diseño por sismo.
This code was already implemented in CYPECAD and Metal 3D as of previous versions. Now, with the 2014.f version the option offered by appendix A of the code has been implemented, whereby for the seismic design of structures located in zones II and III, the effects of the site and ground-structure interaction can be taken into account explicitly.
To apply this possibility, an option “Interacción suelo-estructura” has been implemented in the “Seismic zone” section of the "Code for the calculation of seismic loading” dialogue box (Job > General data > Select “With seismic loading” in the Loads section > Select Mexico and the NTC 2004). This option allows users to define the values of the “Periodo dominante más largo del terreno (Ts)” and the “Factor reductivo por amortiguamiento”, and consider an overresistance factor, if necessary.
