In this study, the methodology recommended by FEMA P695 is employed to evaluate seismic performance of self-centered y-shaped (SCY) braced frames. To apply system interest, twenty archetype models are deigned. The collapse safety then evaluated through incremental dynamic analyses (IDA) and pushover analyses. results show that secondary stiffness length self-centering (SC) element key parameter...

In the building construction, framed structures are frequently used due to ease of construction and rapid progress of work. Masonry infill panels have been widely used as interior and exterior partition walls for aesthetic reasons and functional needs. When infill walls are omitted in a particular storey, a soft storey is formed compared to much stiffer other stories. The masonry infill has bee...

Structural pounding between adjoining multistory buildings with different total heights and story levels has been repeatedly identified as a frequent cause of severe damage during seismic excitations. This phenomenon is very intense when upper floor slabs short hit the columns taller more flexible structures within their deformable length. On other hand, it well accepted that infill masonry pan...
