In some countries like Spain, there is a very useful tool to decide if a structure might suffer from an earthquake and, consequently, if it has to be designed for that purpose or if it is not necessary. This tool is a seismic hazard map.
CUBUS, designed by Swiss engineers, by default, assumes that every construction will be designed to withstand an earthquake, in other words, there is always the need of doing the earthquake analysis of the structure.
CEDRUS’ option H allows, apart from managing the horizontal loads of a building, to generate automatically a framework model in STATIK. This framework model can be used to carry out an earthquake analysis, which is fundamentally what it was created for. However, it is also used to dimension pillars and walls (with an especial analysis in FAGUS over the STATIK model).
That said, for STATIK to generate all the necessary calculations (associated to the Response Spectrum and Equivalent Forces method), we will define a standard spectrum in CEDRUS and then, in STATIK, if so wanted, all the especial analysis are eliminated.
