So u or your senior will always use full ductility (SMF) in any seismic zone?. if yes that's agree well with me, and yes that's true, detailing is what important especially during construction. Even if you are slightly wrong in calculating the R value, slightly wrong in picking seismic zone and not conservative in your seismic force. Trust me your structure will survive, people will be saved than doing all that stuff like PSHA, Pushover or Nonlinear Dynamics. Ductility is the heart of all earthquake resistant design and proper detailing work is what ductility all about, and i think that's what engineer is paid for :), which is provide ductility to the structure :lol:
