Norma Técnica para Diseño por Sísmico (El Salvador)
Implemented in CYPECAD and Metal 3D.
The 2014.i version includes in CYPECAD:
- A static analysis method (equivalent lateral force)
The analysis method selection (dynamic or static) is carried out using the Analysis method option within the dialogue box where the seismic load is defined. - Correction due to base shear
This correction is applied to the seismic analysis using the dynamic analysis (spectral modal) method. To calculate the base shear with the ABNT NBR 15421:2006 code, CYPECAD offers two options for users to indicate the Fundamental period of the structure in two ways:
- Based on the code
- Specified by the user
