In this study, the approximate method adopted by ASCE/SEI is evaluated, first qualitatively and subsequently by comparing its predictions against results. 1 Jan ASCE/SEI provides stringent design criteria for nuclear facilities. Due to the potential risk associated with nuclear hazards, it is desirable. 30 Jul SHORTCOMINGS OF THE ASCE APPROXIMATE METHOD FOR ESTIMATING THE SEISMIC DEMANDS ON ROCKING OBJECTS IN.
