Abstract:Time history response analysis was conducted using a multi mass model assuming low-rise RC an S buildings,and it was shown that the seismic grade determined from the response values was equivalent to the seismic grade determinedby the " simplified method" .

Keywords:performance-based design; static design; low or middle-rise building; seismic performance level; story drift;time history analysis; multi-degree-of-freedom system
