Design of Secondary Seismic Elements with SAP2000/ETABS and VIS
Today we will see how to perform the design of secondary seismic elements, according to the provisions of Eurocode 8.
The code recognizes that a certain number of elements can be considered as not to be part of the seismic-resisting system of the building, and be designed as "secondary seismic members".
Accordingly, the corresponding strengths and stiffness of these elements against seismic actions must be neglected.The main advantage is that secondary elements can be designed for gravity loads only, following the provisions of Eurocode 2.This will allow for slender sections, and, consequently, less structural constraints. A typical example is the case of shallow beams, that could hardly be designed as primary elements due to the poor resulting joint dimension.The whole process can readily be implemented in VIS, using a unique model analyzed in "SAP2000" or "ETABS"
