The hysteretic behavior of partially pre-stressed beam-column joint sub-assemblages made of reactive powder concrete

Reactive powder concrete (rpc) is an alternative to normal concrete (nc) allowing for significantly higher strength of partially pre-stressed concrete structures. in the indonesian national standard sni 03-2847-2013 (2013) and the american standard aci 318-14 (2014),the partial pre-stressed ratio (ppr) is limited to a maximum of 25.0 percent to ensure that pre-stressed concrete structures remain ductile and capable to dissipate seismic energy sufficiently. the objective of this experimental study was to investigate the hysteretic performance of partially pre-stressed-rpc (pp-rpc) for both interior and exterior beam-column joint sub-assemblages. four specimens with different levels of ppr were tested with a combination of constant axial compression and cyclic lateral loads. the ppr used for the first and the second two specimens were 22.8% and 33.8%,respectively. the strength of the rpc was 101.60 mpa for all specimens. the results showed that increasing the ppr of pp-rpc improves its hysteretic performance. the best performing specimen,with a ppr of 33.8%,had a ductility that was 1.97 times that of the specimen with a ppr of 22.8%. © 2016 published by itb journal publisher.
