Representation of near-fault pulse-type ground motions
Near-fault ground motions with long-period pulses have been identified as critical in the design of structures. To aid in the representation of this special type of motion, eight simple pulses that characteriz...

An improved modal pushover analysis procedure for estimating seismic demands of structures
The pushover analysis (POA) procedure is difficult to apply to high-rise buildings, as it cannot account for the contributions of higher modes. To overcome this limitation, a modal pushover analysis (MPA) proc...
