Seismic Performance Of Six And Twelve Story Staggered Wall Structures With Middle Corridors

In this study the seismic performance of sixand twelve-story staggered wall structures with middle corridor was evaluated based on the FEMA P695 procedure. The validity of the seismic response factors used for seismic design of the model structures was also evaluated following the procedure. The analysis results of the prototype structures were compared with those of the structures with increased coupling beam depth or increased re-bar ratio of coupling beams. The adjusted collapse margin ratios of the model structures obtained from incremental dynamic analyses turned out to be larger than the limit states specified in the FEMA P695, which implies that the analysis model structures have enough safety margin for collapse against design level earthquakes.
