RC-SEC-EN is a software for the calculation of reinforced concrete sections according to EN 1992-1-1 and EN 1998-1 and eventual national application annexes. This software is a standalone application for checks of reinforced section belonging to beams, columns and walls. In seismic checks is considered the class of ductility demand (DCL, DCM or DCH) and whether or not the section is within a critical region of the member. If the checks are not seismic you must select the low ductility class (DCL) and so only EN 1992-1-1 is applied.
